What each unit is
- millimeter mm
- A thousandth of a metre, and the working unit of engineering drawings, rainfall and camera focal lengths.
- centimeter cm
- A hundredth of a metre. The everyday metric unit for anything you can hold — body measurements, paper, screens.
Where these come from

- 1 centimeter = 0.01 meters
Every other number on this page is computed from those, and each category is pinned to conversions worked out by hand from the units' primary definitions before it ships.
