Length Converter
A length converter converts between metric (meters, km, cm, mm) and imperial (feet, inches, miles, yards) units. The metric system uses powers of 10; the imperial system uses irregular multipliers inherited from historical standards.
💡
Pro Tip
Rough conversion shortcuts: 1 km ≈ 0.6 miles, 1 meter ≈ 3.3 feet, 1 inch ≈ 2.5 cm. For km to miles: multiply by 0.6 (or divide by 1.6).

Did You Know?
The meter was originally defined in 1793 as one ten-millionth of the distance from the North Pole to the equator along the Paris meridian. Today it's defined by the speed of light: the distance light travels in 1/299,792,458 of a second.
