What This Converter Does
Length measures distance - how long something is. Every length unit measures the same thing, so converting just rescales the number: 1 inch is exactly 2.54 cm, and the metric units step by tens (10 mm = 1 cm, 100 cm = 1 m).
Convert a length from one unit to another — metric (mm, cm, m, km) and imperial (in, ft, yd, mi), in any combination.
How to Use It
- Enter the value.
- Choose the unit to convert from and the unit to convert to.
