Length Units & Calculator
Use length for a single dimension. Multiply two compatible lengths for area and three for volume. The foot here is the international foot, not the legacy U.S. survey foot.
Detailed explanation & worked examples
Conversion method
Base value = input × source factor + source offset. Output = (base value − target offset) ÷ target factor. Only units from this family can be converted together.
Worked example
For the first two units below: 1 Millimeter (mm) becomes 0.10000000 Centimeter (cm).
| Unit | Multiplier | Offset |
|---|---|---|
| Millimeter (mm) | 0.001 | 0 |
| Centimeter (cm) | 0.01 | 0 |
| Meter (m) | 1 | 0 |
| Kilometer (km) | 1000 | 0 |
| Inch (in) | 0.0254 | 0 |
| International foot (ft) | 0.3048 | 0 |
| Yard (yd) | 0.9144 | 0 |
| Mile (mi) | 1609.344 | 0 |
| Nautical mile | 1852 | 0 |
