Pretty close (but I hope they don't use it for calculating artillery ranges).Īgain, though, there's a formula that's almost as easy to work out in your head but delivers a precise result. You can also divide by three and multiply by five: 90 ÷ 3 = 30 x 5 = 150. Express that as 15.0 and move the decimal point one place right and arrive at 150. This is why British and American soldiers stationed in Germany were taught an 'on manoeuvres' converter: divide the miles by six and move the decimal point one point to the right. Double back again and we get to 144.Īs an alternative, let's think about about a kilometre equalling (roughly) six tenths of a mile. So that 18 could be halved to nine and we all remember, don't we, that nine eights are 72. One way to solve it is to reduce the principal number to something that appears in the eight times table then convert it back. So, yes, of course it works but there's a problem While dividing by five is easy enough (divide by ten and double it), multiplying by eight is trickier. What about going the other way, for the European traveller trying to convert those weird miles into nice neat kilometres? Well, the obvious way is to divide by five and then multiply by eight.
#Conversion miles kilometre heure how to
For example, here's how to convert 5 miles to kilometers using the formula above. Since one mile is equal to 1.609344 kilometers, that's the conversion ratio used in the formula. The distance in kilometers is equal to the distance in miles multiplied by 1.609344. The fastest way to convert miles to km (kilometers) is to use this simple formula: There are 1.609344 kilometers in a mile, which is why we use this value in the formula above.ġ mi = 1.609344 km How to Convert Miles to Kilometers Kilometers can be abbreviated as km for example, 1 kilometer can be written as 1 km. In the metric system, "kilo" is the prefix for 103. The kilometer, or kilometre, is a multiple of the meter, which is the SI base unit for length. One kilometer is equal to 1,000 meters, which are defined as the distance light travels in a vacuum in a 1/299,792,458 second time interval.
For example, 1 mile can be written as 1 mi or 1 m. Miles can be abbreviated as mi, and are also sometimes abbreviated as m. The mile is a US customary and imperial unit of length. One mile is also equal to 5,280 feet or 1,760 yards. The mile is a linear measurement of length equal to exactly 1,609.344 meters.

The world is full of different units of measure, and it's important to know how to convert from one unit to another. Symbols, abbreviations, or full names for units of length,Īrea, mass, pressure, and other types.Miles and kilometers are both units used to measure distance or length. You can find metric conversion tables for SI units, as wellĪs English units, currency, and other data. It is commonly abbreviated in everyday use in the United States, the United Kingdom, and elsewhere to mph or MPH, although mi/h is sometimes used in technical publications.Ĭonversion calculator for all types of measurement units. Miles per hour is a unit of speed, expressing the number of international miles covered per hour. The km/h is the worldwide most commonly used speed unit on road signs and car speedometers. The kilometre per hour (American English: kilometer per hour) is a unit of both speed (scalar) and velocity (vector).
