    How many Feet equal one Kilometer?

Kilometers and feet are units used to measure length or distance. 1 kilometer is about 3280.84 feet, according to the International System of Units (SI)[1] standard adopted with an international threaty in 1959. A kilometer is part of the metric system while a foot is a part of the imperial system of units. The standard symbol for kilometers is "km", while the standard symbol for feet is "ft"[2].

The kilometer is defined as exactly 1000 meters, while a meter is defined as the distance light travels in 1/299,792,458 seconds in a vacuum (since 1983). It was first defined in 1793 as 1/10,000,000 of the distance from the equator to the North Pole, but just 6 years later it was redefined in terms of a prototype metre bar of metal. In 1960 it was redefined once again, this time in terms of a certain number of wavelengths of a certain emission line of krypton-86.

Historically, the foot varied in length from country to country and from time to time as there was no central standartization authority. It was usually between 250 mm and 335 mm, but is nowadays fixed at exactly 0.3048 meters. The kilometer is used in almost all countries in the world, while the foot is widely used only in the United States. It is partially used in Canada and the United Kingdom, where road signs must use imperial units, but distances on them are usually given in miles or yards, not feet. Height measurements are often done in feet is well.

    How to convert Kilometers to Feet?

Conversion from kilometers to feet is done both for distance, volume and very often for height measures, for example in aviation. There are different approaches to converting kilometers to feet, but a simple one is to calculate how many kilometers is one foot equal to. Since a foot is 0.3048 meters and a meter is 1/1000 of a kilometer, then a foot is 0.0003048 of a kilometer. Then, if you need to convert 1 kilometer to feet, that would be 1/0.0003048 = 3280.839895 feet. 10 kilometers would then be 10 divided by 0.0003048 = 32808 feet (approx.).

Care should be taken when converting units from historical texts. For example, the current international foot is 2ppm shorter than the previous U.S. standard and 1.7ppm longer than the previous British standard.

Warning! Do not follow the advice given in some places to simply multiply the number of kilometers to the number of feet equal to one kilometer, e.g. 10km = 10x3280.84 = 32808.4 feet. Since that number is not a precise decimal number: 3280.8398950131233595800524934383... and so on, you are bound to get errors due to rounding. While the error is negligible for most practical purposes it is still preferred to use the correct conversion formula.

Km to Feet conversion example

Sample task: convert 5 kilometers to feet. Solution:

km / 0.0003048 = ft
5 km / 0.0003 = 16,404.199475 ft
End result:
5 km is equal to 16,404.199475 ft
