Distance Unit Converter
Convert a distance or length into every common unit at once: kilometres, miles, metres, feet and inches, yards, nautical miles and more.
About this tool
Type a number and choose its unit, or type a mixed length such as 5 ft 11 in, and every conversion appears at once. Feet and inches is handy for heights and room sizes. The UK uses miles and yards on road signs, metres and kilometres for most other things, and feet and inches for people’s heights, so conversions come up constantly.
All units use their exact legal definitions: an inch is exactly 2.54 cm, a mile 1,609.344 m and a nautical mile 1,852 m, the unit used at sea and in the air. Furlongs (220 yards) survive in horse racing, chains (22 yards, the length of a cricket pitch) on the railways, hands (4 inches) for measuring horses, and fathoms (6 feet) for water depth.
