Unit Converter

How it works

For most categories, each unit is converted to a common base unit (like metres for length, or kilograms for weight) using standard conversion factors, then converted to the target unit. Temperature uses direct formulas between Celsius, Fahrenheit and Kelvin since they don't share a simple multiplicative base.

Example

10 kilometres converts to 6.21 miles. 100°C converts to 212°F.
