How much is 1 statute mile. What is a nautical mile and what is the sea knot

Very often in English and American literature you can find not entirely clear metric units such as miles, feet, yards, inches - especially if the translator is too lazy to convert them into meters and kilograms that are convenient for our perception.

A mile (from Latin milia passuum - a thousand double Roman steps) is a travel measure for measuring distance.

1 mile = 1.609344 kilometers

The mile was used in a number of countries in antiquity, as well as in many modern countries before the introduction of the metric system of measures. In countries with a non-metric system of measures, the mile is still used today. The size of a mile is different in different countries and ranges from 0.58 km (Egypt) to 11.2 km (Old Bohemian mile).

• Ancient Roman (milliatrius): 1 mile = 1.598 km (according to other sources 1.480 km)
• Starorusskaya: 1 mile = 7 versts = 7.4676 km
• British and American: 1 mile = 8 furlongs = 1.6093 km
• Geographic (German): 1 mile = 1/15° equator = 7.420 km

Nautical mile- a unit of distance used in navigation and aviation.

The nautical mile was originally defined as the length of a great circle on the surface of the globe, measuring one minute of arc. Thus, a movement of one nautical mile along the meridian roughly corresponds to a change in geographic coordinates for one minute of latitude.

By modern definition, an international nautical mile is equal to 1852 meters (exactly).

International nautical mile = 10 cable

UK nautical mile = 1853.184 meters (until 1970).

The French had at least two miles - land and sea, and their dimensions were displayed as part of the length of the arc of the earth's meridian. How many kilometers in a land mile, calculated from 1/25 ° of the earth meridian, and this is 4444.4 meters, that is, almost 4.5 kilometers, similarly, a nautical mile, 1/20 ° of the earth meridian, and this is 5.555 km.

Milliatrius, she is the ancient Roman mile, equals 1.482 km. The old Russian mile was equal to seven versts, and now it is almost 7.5 kilometers, about the same value - 7420 meters is the German one mile. How many kilometers the Swedes and Norwegians equate to one mile is 10.668 km and 11.298 km respectively. True, after the adoption of the law on metric measures, both countries equated a mile to exactly ten kilometers.

How many kilometers in a mile are there now

Now there is a concept of two miles - nautical and land.

The nautical mile is equal to 1862 meters, the American land mile is equal to 1.609344 kilometers.

To calculate how many kilometers are in a mile, for an approximate value, simply multiply the number in miles by 1.6. That is, approximately 1609 meters are obtained. A nautical mile is also larger than a land mile and includes approximately 1,852 kilometers or 1,852 meters.

So, a car speed of 40 miles per hour would be approximately equal to the metric 65 kilometers per hour.

1 mile is equal to:

• 1.609344 km;
• 1609.344 m;
• 16093.44 dm;
• 1609344000 µm;
• 63360 inch;
• 1609344 mm;
• 160934.4 cm;
• 5280 ft;
• 1760 yards;

Mile

This measure of length came to us from antiquity and has many varieties and, as a result, values ​​- from 580 meters in an Egyptian mile to more than 11 kilometers in a Norwegian one. However, in the vast majority of cases, a mile is understood as a British (or American) mile - 1609 meters 34 centimeters. So if in a text or a movie you come across a mention of the length in miles, and you need to roughly estimate how much it will be in kilometers, feel free to multiply by 1.5. However, it is also necessary to distinguish the nautical mile, which is used in navigation and aviation - it is slightly longer and is 1852 meters.

Inch

According to legend, the length of the upper phalanx of the thumb was taken as the basis of the inch. Of course, finger to finger is different, and therefore the generally accepted value is 2.54 centimeters. So if now your child asks how tall Thumbelina was in Andersen's fairy tale, you can answer with accuracy.

Foot

Since a foot is 12 inches, it is quite easy to calculate the value: 30.48 centimeters. Thus, if you come across a value in feet, and you are more accustomed to being aware of it in meters, then simply divide it by three. Thus, the old nautical wish “fair wind and seven feet under the keel” meant that 2 meters 10 centimeters should be enough so that the ship does not hit the ground.

Yard

That's three feet, or 91.44 centimeters. Since the yard is only slightly short of the meter, then if you do not need high accuracy, you can not even translate this metric unit. And the name of the famous comedy with Bruce Willis "The Nine Yards" no longer seems like an incomprehensible set of letters. (However, in fairness, we note that the name is a phraseological unit and is translated as "everything to the end, without a trace").

Acre

A word that is often used in crossword puzzles and is the answer to the question "English measure of area." Indeed, by an acre, the ancient English meant a piece of land that a pair of bulls cultivates in a day. An acre is exactly 4046.86 square meters, or approximately 1/250 of a square kilometer. You will not envy that pair of bulls, which will have to process a square kilometer of land - after all, they will have to work for eight whole months!

Lb

Not to be confused with foot! If a foot means distance, then a pound means the mass of an object. By the way, the pound sterling was originally a pound of silver coins, 453.6 grams, that is, almost half a kilo. Very often, modern exercise machines such as a bicycle or a treadmill offer to enter body weight before starting a session. Be careful, because if the simulator is made in England or the USA, then most likely it asks you to specify the weight in pounds. But this is not a problem - just double your weight in kilograms and report it to the simulator. (But when starting to cook according to old Russian cookbooks, keep in mind that the Russian pound is smaller, only 410 grams.)

Ounce

This is 1/16 of a pound, which is 28.35 grams. It is used in medicine for weighing preparations, as well as in perfumery. Look at the packaging of your perfume - you will probably find a designation like 3.3 fl. oz. - this is the designation of the mass (or, more precisely, volume) of perfume in ounces.

For most cases, the listed units will be enough, so now you do not have to puzzle over the English notation for length or mass. Simple rules will not only keep your peace of mind when reading an interesting book that has not been processed by a lazy translator, but will also make you more erudite. After all, if a penalty kick in football breaks through from a distance of 12 yards, then it’s not so difficult to convert this value into meters, right?

All countries of the world are striving for a universal standardization of the system of measures, but still there are some units of measurement duplicating each other. In many countries, distances are now measured in miles and feet.

The metric system is more familiar to Russians and residents of the CIS countries, so the designation of the distance in miles introduces many into a stupor. But how many km are in 1 mile or how many miles are in one kilometer? We will help you understand this and look at the types of miles used in the world.

What is a mile?

A mile is a unit of measurement used primarily in America and the UK. You may have noticed that the distance and speed are shown in miles on the speedometers of American and British cars. Moreover, this value is found in books on navigation, but a land mile is different from a sea mile.

In Latin, the unit of measurement is called the mille passuum. A mile is equivalent to a thousand double steps of Roman soldiers in full uniform during the march. This unit was first used in ancient Rome to measure the length of the path. Until the metric system appeared in the world, the mile was used everywhere, and in some countries this unit was preserved. But how many km are there in a land and sea mile?

How many kilometers in nautical and statute miles?

As you already know, miles are different. There are only 1608 meters in a modern land mile, and one nautical mile is 1852 meters or 1.85 km. By default, in business documents of international format and other designations, it is the British statute mile, also called the American one, that is why you can remember the following ratios for ease of calculation:

• 1 mile is equal to 1.6 km or 1608 meters;
• 2 miles is 3.2 km;
• 5 miles equals 8.04 km;
• 100 miles is 169 km.

Other types of miles

There are also French, German and even Swedish miles. There is a German or so-called geographical mile, which was equated to 1/15 of the equatorial parallel. Accordingly, 1 German mile is 7.42 km. The French, in turn, divided the sea and land miles, equating them to a fraction of the meridian of the planet:

• 1 French statute mile = 4.44 km;
• 1 French nautical mile = 5.55 km.

The Swedes also had their own mile, equal to 10.6 km, but when approving the international measurement system, they shortened it to 10 km. In everyday life, you are unlikely to need these values, and most often you will ask questions, how many km are in an American mile? You already know this - 1 British or American mile is equal to 1.6 km.

Back in the days of the ancient Romans, one land mile was equal to 1000 steps. Later, a specific figure was set - 1609 meters. The length of a nautical mile was 1852 meters. Where did this one come from?

A bit of history...

It was inconvenient for sailors to use statute miles to measure the speed of a ship. Especially, there were unjustified risks during emergency work. From the raging elements during the storm, the life of sailors was in great danger. Under such conditions, it was not possible to use land measurements.

Therefore, we found a more suitable option. They took a heavy log and threw it overboard. Then they counted how many knots will pass through the sailor's hands for a certain period of time before the rope is pulled.

Empirically determined the distance between the nodes and the time interval. There are different versions about the exact definition. One of them, when the distance between the nodes averaged 15 meters. It took 30 seconds in time.

It was practical and rational. The countdown was measured with an hourglass. All that remained was to count the knots and look at the sand. The task could be performed even by an illiterate sailor.

We summed up these studies and found out. The length from one knot to another to the tension of the rope is 15 meters, in time it takes 30 seconds. By simple arithmetic operations, the average speed of the ship was calculated. Thus, one nautical mile was 1852 meters in one hour.

Further developments

With the development of navigation, even greater convenience was introduced. One nautical mile became equal to one minute along the meridian. 1 degree equals 60 minutes. This will be 60 nautical miles. The nautical mile has become convenient for calculating navigation tasks.

Therefore, the navigators began to measure the distance with a compass. By attaching it to the scale, they recognized the distance in nautical miles. For example, to find out a distance of 30 miles, 30 minutes of arc on any meridian marked on the map is enough with a compass.

Now, of course, all equipment is computerized. There is no need to use outdated methods, but the nautical mile, as a unit of distance, has remained unchanged and amounted to 1852 meters. It is called navigational or geographic.

The knot is used in shipping as the basic unit of speed. Nautical miles and knots are the same clear and familiar measurements at sea as kilometers and meters on land.

Sources:

• Units. What is the SI system?
• Why are nautical miles different from land miles, while nautical and land kilometers are the same?
• Why is a nautical mile different from a land mile?
• What is a nautical mile and what is the sea knot?

Speed ​​on land is measured in units of time taken to travel one kilometer - kilometers per hour. On the water, speed is measured in knots - special units that are characteristic only for navigation.

According to encyclopedic dictionaries, a knot is a measure of length equal to 1 nautical or 1852 meters. Thus, a ship moving at a speed of one mile per hour, or 1 knot per hour, covers a distance of one kilometer and 852 meters in one hour. What is the reason for such, at first glance, strange features of taking measurements in shipping and?

Node Birth

What does nautical mile mean?

Nautical mile - approximately two kilometers, or rather, 1852 meters. The Great Soviet Encyclopedia mentions that this value was approved in 1929 at the International Hydrographic Conference. It is considered correct in the CIS countries and a number of other states, although it is not included in the list of the international system of units.

Where did the meaning come from? It is known that the distance of 1853 meters is the approximate linear length of one minute of latitude, that is, 1/60 of the meridian arc. It should be noted that this length of the meridian corresponds only to the average latitudes of the globe. We add that a nautical mile contains 10 cables.

The value of the nautical mile in the UK was slightly different, where until 1929 it was assumed that 1853 meters. This was due to the convenience of converting an ordinary mile into a nautical mile. In this case, it was enough to add the number 800 to the mile to get the nautical mile in feet.

What does sea knot mean?

The sea node displays a certain speed of the vessel. A ship that has traveled one nautical mile per hour has made one nautical knot. The number of nautical miles a ship travels in one hour is equal to the number of knots. Moreover, it is not customary to talk about the speed of the vessel, as the number of knots per hour. If it is indicated that the ship makes twelve knots, it means that it overcomes the same number of miles in sixty minutes.

Why did the maritime knot get its name? It turns out that this concept is associated with a marine instrument that previously measured the speed of a vessel - a lag. The lag was a long load that was thrown overboard. The rope was pre-knotted in 50-foot increments. After that, the captain or his assistant counted the number of knots on the cable that would sink into the water in a certain time. Their number corresponded to the speed of the vessel.

Nowadays, the speed of a ship in knots is rarely measured, only in Britain it is customary to talk about nautical per hour. In most countries, maritime transport speed is measured in kilometers per hour.

Accumulating miles under the Aeroflot bonus program will allow you to receive a pleasant “gift” after a while - a free flight or an upgrade, instead of an economy ticket, you can get a business ticket. There are several ways to earn miles, and it is best not to limit yourself to one of them, but to work with all of them at once.

Instruction

All bonus miles that can be accumulated with Aeroflot are conditionally divided into qualifying and non-qualifying. The first type includes all award miles that you receive when flying on the flights of Aeroflot itself and partner companies. The second type of miles is accumulated if you use various joint programs of Aeroflot with partners, for example, with hotels, banks, mobile operators, and so on.

The easiest and most effective way to quickly earn qualifying miles is to fly with Aeroflot and partner airlines. With every flight, you earn at least 500 bonus miles, and if it's a long-haul flight, even more. The most profitable are flights in business class, for which sometimes double or even more is charged than for a flight in economy class. The airline's website is present, which allows you to calculate how many bonus miles you will receive in each case.

From time to time, Aeroflot holds various promotions, according to which much more miles are credited for flights in certain directions than usual. Of course, no one will buy a ticket to faraway lands just because this month you can get a large number of award miles for it. But if you are going on vacation anyway and have not decided yet, then why not see what offers Aeroflot has for you?

Not so long ago, Aeroflot joined the Sky Team alliance, which includes many of the largest carriers from around the world. Therefore, it is useful to find all boarding passes for the last year or two, and if any flights were made on aircraft of companies from this alliance, then you can safely enter their data on the bonus program website in order to credit miles to your bonus account. You can also use all Nordavia flights.

Non-qualifying miles are an opportunity to earn for non-frequent flyers. To find out how you can accumulate them, it is useful to go to the Aeroflot website from time to time and look at the list of partner companies for purchases from which you receive miles. The list of partners is constantly changing. These are all kinds of hotels, bank cards, and even mobile operators (Aeroflot's partner is Megafon). Sometimes, promotions that are beneficial in terms of miles are held together with partners.

Some ways of earning non-qualifying miles give you a good bonus when you sign up. So, when you open a bank card from which miles are credited for every purchase, you usually receive 500 welcome miles. The company also gives its customers a gift - a certain number of miles for their birthday, provided that the person is an active client and has accrued lately.

Helpful advice

The number of miles you earn depends on your status as a customer. Upon registration, everyone receives a Basic status, but later, if you are active, you can move to the Elite club. Its members have access to various benefits and privileges, including an increased number of accrued miles. It turns out that the more miles you accumulate with Aeroflot, the easier and faster it will be for you to do it in the future.

Bonus miles are a kind of means of payment with which you can upgrade the class of service on an airplane or purchase a free flight. There are various ways to earn bonus miles.

Each passenger participating in the Aeroflot Bonus program can open only one account in it, qualifying miles from which cannot be transferred or combined with miles and accounts of other participants in this program. In addition, a member may not transfer, sell or bequeath their qualifying miles account to a third party or use it to earn awards in other rewards programs.

Mileage Rules

Qualifying miles for a flight with Aeroflot or an airline that is a partner of the program are credited to the passenger's account once and regardless of the number of services or air tickets paid for by him. The accrual of qualifying miles occurs in accordance with the distance traveled between the point of departure and the point of destination - while they are credited to the account only after completed flights.

The program member receives qualifying miles as a percentage of the distance covered and depending on the fare indicated on his ticket.

Also, qualifying miles are credited to the passenger's account for each flight segment that corresponds to each flight ticket coupon. In the Aeroflot-Bonus program, these rewarding conditional units are credited exclusively for a flight coupon or air ticket already used by a passenger. At the same time, qualifying miles are not credited in case of lost, expired or unused tickets. They are credited to the account of the program participant automatically after the flight and within ten days after the flight date. Also, the number of a passenger participating in the airline's bonus program must be entered into the Aeroflot booking system.

A mile is a unit of measure for distance dating back to ancient Rome. Translated from Latin, it means 1,000 steps. The military - the Romans, walking along the roads of the empire, measured the distance with double steps. Initially, the Roman mile corresponded to 1475 meters. This measure was used in many countries in antiquity. However, with the introduction of the metric system of measures, known as the SI, its use has been greatly reduced. One way or another, today in some countries this travel measure of length is still used. It should be noted that the length of a mile varies greatly in different parts of the world from 0.58 km to 11.3 km. Moreover, back in the 18th century in Europe, there were about 46 units of measurement, which were called miles.

To date, several types of miles are found in everyday life in different areas. Speaking about the most popular of them, we can name:

• Land miles
• Nautical miles

Let's consider each of them in more detail.

Nautical miles

A nautical mile is a unit of measure for the distance traveled by a ship between destinations. This measure is widely used in navigation as well as in aviation. In fact, this is the average length of the arc of one arc minute of the meridian. Gerard Mercator, a Flemish cartographer and geographer, suggested using this measure. In Russia, the nautical mile has been used since the time of Peter the Great. And today, when seafarers are offered to move to kilometers, they answer that they do not plan to do this. However, it is justified. After all, a nautical mile is, in fact, a path corresponding to the distance between two geographical coordinates in one minute of latitude.

How many kilometers are in a mile? Here are the formulas for converting miles to kilometers and vice versa.

Nautical mile to kilometers conversion formula

1 nautical mile = 1,852 meters = 1.852 kilometers

Derive the formula for converting a kilometer to a nautical mile

1 nautical mile = 1.852 kilometers
1,000 nautical miles = 1,852 kilometers
1 kilometer = 1000/1852 miles (approximately equal to) 0.54 miles

Formula to convert kilometers to nautical miles

1 kilometer = 1000 / 1852 miles? 0.54 miles

Land miles

The land mile is used primarily in English-speaking countries, and corresponds to a value of 1,609 meters. The statute mile is used in the United States and is sometimes referred to as the American mile for this reason. Accordingly, if you want to know: how many kilometers are in a US mile or, which is the same, how many km are in a US mile, then the above value should be used. Also, this unit can be found under the names British or statute mile.

Formula to convert statute miles to kilometers

1 statute mile = 1,609 meters = 1.609 kilometers

Kilometer to statute mile conversion formula

1 km = 1000/1609 statute miles = 0.6215 statute miles

In addition to those described, there are also:

• geographical or German mile equal to 7,420 meters (7.42 km);
• an old Russian mile equal to 7,467.6 meters (7.4676 km).

1 mile is how many kilometers in Russia?

I would also like to note that in Russia this measure of length is not used, because there is nothing to measure in these units of measurement in the Russian Federation. Sailors have worldwide nautical miles (see above).

Often there is a need, for example, when solving a problem to find out: how many miles are in a kilometer or vice versa? Here it is worth clarifying which mile (land or sea) you need to transfer. Or maybe an old Russian mile or a German one? And already depending on this, you can translate this value into the usual kilometers. Let's consider several problems of converting miles to kilometers and vice versa. For definiteness, let's clarify that to solve problems we will convert nautical miles into kilometers (1 nautical mile = 1.852 kilometers).

Convert miles to km

How many miles are in N kilometers?

Consider inverse problems of finding the number of kilometers in a mile? And we will convert kilometers to statute miles (1 km = 0.6215 miles).
