How length conversion works

Every length conversion here goes through the meter. Since 1959 the inch has been defined as exactly 2.54 centimeters, so the imperial units convert exactly: a foot is 30.48 cm, a yard is 0.9144 m and a mile is 1,609.344 m.

For quick mental checks, 1 meter is about 3.28 feet and 1 kilometer is about 0.62 miles. Heights are usually written in feet and inches (5 ft 9 in is 175.26 cm), which the converter accepts as typed.
