How does it work?

Converting lengths means multiplying by a fixed factor: every unit has an exact equivalent in meters, so going from one to another is always the same calculation. This tool does it for you in both directions.

Watch out for the imperial system: a mile is exactly 1,609.344 meters, a foot 0.3048 and an inch 0.0254. These are exact definitions, not approximations.
