Unit Converter

Supported conversions

This converter covers the three unit categories people need most often: length (millimeters to miles), weight (grams to pounds), and temperature (Celsius, Fahrenheit and Kelvin). Length and weight conversions use precise multiplicative factors based on a common base unit (meters and kilograms respectively), while temperature uses the correct additive formulas since Celsius, Fahrenheit and Kelvin scales don't share a common zero point.
