Unit converter

Converts length, weight, temperature, and volume between units of the same kind.

When you want a fixed-factor check between metric and everyday units.

Length, weight, and volume use a fixed factor to a base unit. Temperature goes through kelvin so the Celsius and Fahrenheit offsets are applied.

Example: 1 km is 1000 m. 0°C is 32°F. 1 US gallon is 3.785411784 L.

Assumptions: same kind of unit only. Length uses metres, weight kilograms, volume litres. Temperature goes through kelvin. The display uses 8 significant digits.

Limits: ml to grams for food is not offered, because that needs a density. The typed number is not sent to analytics. This is not a legal metrology calibration.
