All units for this value
| Unit | Value wey e get |
|---|
All seven units na di same length dem describe. Di inch and foot factors below na exact definitions.
Formula
Target value = input × original-unit factor ÷ target-unit factor; di factors na metres for each unit.
| Unit | Metres for each unit |
|---|---|
| Metre (m) | 1 |
| Kilometre (km) | 1,000 |
| Centimetre (cm) | 0.01 |
| Millimetre (mm) | 0.001 |
| Inch (in) | 0.0254 |
| Foot (ft) | 0.3048 |
| Mile (mi) | 1,609.344 |
Di definition of inch na exactly 0.0254 m, so di foot (12 inches) and international mile (5,280 feet) na exact too.
Example wey show the calculation
1 m ÷ 0.3048 m/ft = 3.280840 ft, and 1 m ÷ 0.0254 m/in = 39.370079 in. One 5 km run na 5,000 ÷ 1,609.344 = 3.106856 miles.
