Length is measured in metric in most of the world and in imperial units in a few influential places, which makes conversion a constant need. The Length Converter translates between millimetres, centimetres, metres, kilometres, inches, feet, yards and miles, so a measurement makes sense whatever system it came in.

How to use the Length Converter

  1. Enter a value and choose the unit it is in.
  2. Pick the unit you want to convert to.
  3. Read the converted result and copy it.

Bridging metric and imperial

Whether you are following furniture dimensions from an overseas shop, working out a running distance, reading a recipe, or planning travel, you will eventually hit a unit you do not think in. Metric units scale neatly by powers of ten, while imperial units have their own historical relationships (twelve inches to a foot, three feet to a yard). This converter handles all of those relationships precisely, so you get an accurate figure without memorising conversion factors.
