## About this conversion

Converting feet to kilometers is a conversion between units from separate unit systems - feet are US Customary / UK Imperial defined units while kilometers are metric (SI) .

## About Feet

Customary/Imperial UnitThe foot is a length unit of measure within the US Customary and UK Imperial systems. It is commonly abbreviated as ft or using the ' symbol. The official definition of the foot is 0.3048 meters. Within the Imperial system, the foot is equal to 12 inches or 1/3 of a yard. The foot is very widely used within the United States in situations where nearly the rest of the world would measure in meters. Globally, the foot is used by the aviation community as the standard measurement of flight altitude eg. 35,000 feet.

## About Kilometers

SI UnitWithin the SI (metric) system of measurement, the kilometer is officially defined as being equal to 1,000 meters. It is commonly used as measurement for geographic distances in similar circumstances where a mile would be used in the U.S. Internationally it is spelled 'kilometre' whereas the U.S. spells it 'kilometer'. The symbol for a kilometer is km however k is sometimes used.
