Feet (ft) to Kilometers (km) Conversion
Feet
The foot is a unit of length equal to exactly 0.3048 metres, defined by the international yard and pound agreement of 1959. Today it is the primary unit of height measurement in the United States and the United Kingdom, and is used in aviation worldwide to express altitude, where flight levels are defined in hundreds of feet. One foot equals 12 inches and one third of a yard.
Kilometers
The kilometre, equal to exactly 1,000 metres, is the standard unit for measuring distances at a geographic and infrastructural scale, including road distances, flight paths, and the dimensions of countries and continents. It is derived directly from the metre by applying the SI prefix kilo- (from Greek khilioi, meaning thousand) and is universally used in science, meteorology, and everyday life in all countries that have adopted the metric system. The Earth's circumference at the equator is approximately 40,075 km, a value historically used in the original derivation of the metre itself.
