How It Works
Formula
Variables, symbols and units
- Input value
- Converted length
- Conversion factor of the source unit (meters per unit)(m)
- Conversion factor of the target unit (meters per unit)(m)
Calculation method explained
The calculator converts your value into meters as a base unit, then converts from meters into the target unit. This keeps metric and imperial length conversions consistent across every pair.
Reference factors used by the calculator (meters per unit):
- 1 mm = 0.001 m
- 1 cm = 0.01 m
- 1 m = 1 m
- 1 km = 1000 m
- 1 in = 0.0254 m
- 1 ft = 0.3048 m (12 in)
- 1 yd = 0.9144 m
- 1 mi = 1609.344 m
The value is first multiplied by the source factor to get meters, then divided by the target factor to land in the chosen unit.
