How it works
Unit conversion multiplies a value by a conversion factor to express the same quantity in different units (length, weight, temperature, volume, etc.).
Examples
- 1 inch = 2.54 cm. 1 kg ≈ 2.20462 lb. 1 litre = 1000 mL.
- Temperature conversions are affine: °F = °C × 9/5 + 32; K = °C + 273.15.
Assumptions
- Uses standard conversion factors. Rounding may apply to displayed results.
