more definition+In relation to the base unit of => (meters), 1 Miles (mi) is equal to 1609.344 meters, while 1 Kilometers (km) = 1000 meters. ![]() More than 800 marathons are held throughout the world each. The marathon can be completed by running or with a run/walk strategy. Since one mile per hour is equal to 1.609344 kilometers per. A league is a unit of length.It was common in Europe and Latin America, but is no longer an official unit in any nation.Derived from an ancient Celtic unit and adopted by the Romans as the leuga, the league became a common unit of measurement throughout western Europe. The marathon is a long-distance foot race with a distance of 42.195 kilometres (26 miles 385 yards), usually run as a road race, but the distance can be covered on trail routes. The kilometer (SI symbol: km) or kilometre (British spelling) is a unit of length in the metric system, equal to 1000 meters (kilo- being the SI prefix for 1000). The speed in kilometers per hour is equal to the speed in miles per hour multiplied by 1.609344. The mile (abbreviation: mi) is a unit of distance on land in English-speaking countries equal to 5280 feet, or 1760 yards (1.609 kilometers). How to convert Miles to Kilometers (mi to km)?Īlways check the results rounding errors may occur. Then double the resulting number.The base unit for length is meters (SI Unit) Divide the number of miles by five and subtract that from the original.

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. AdvertisementsĪs 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. Then take a quarter of your half, 18, and just add the two together. You take the kilometre number, 144, and halve it 72. ![]() ![]() What I can do is to remember that, more sensibly, five miles equals eight kilometres and to use a trick an uncle taught me on an early drive through France. The standard 'converter' approach applied to the common problem of turning, say, 144 kilometres into miles would require you to remember that one km equals 0.62137119 miles and being able to multiply that by 144 in your head. We'll take you through some tips for how to manually calculate the figures in your head, plus we'll give you a converter so that you can check your answers. Today we're going to take a look at how to convert between kilometers and miles, and back again. By Nick Valentine | Last update: 07 August 2019
