How It Works
The Length Converter supports all major metric and imperial length units. It converts by first normalizing the input value to meters (the SI base unit), then converting from meters to the target unit.
Supported units and their relationships:
- Millimeter (mm) — 1 mm = 0.001 m
- Centimeter (cm) — 1 cm = 0.01 m
- Meter (m) — SI base unit of length
- Kilometer (km) — 1 km = 1,000 m
- Inch (in) — 1 in = 0.0254 m (exactly)
- Foot (ft) — 1 ft = 0.3048 m (exactly)
- Yard (yd) — 1 yd = 0.9144 m (exactly)
- Mile (mi) — 1 mi = 1,609.344 m (exactly)
All conversions use internationally agreed-upon exact definitions, ensuring complete accuracy. The tool processes everything locally in your browser with no data sent to any server.
