Convert between everyday units of length, mass, and temperature without hunting for a formula. Pick a starting unit and a target unit of the same kind, and the value updates instantly.
How conversions work
Each unit is defined relative to a base — meters for length, kilograms for mass, and Celsius for temperature. The tool converts your value into that base and then out to the unit you chose, which keeps every pairing consistent.
Temperature is a little different: because scales like Fahrenheit and Celsius don't share a zero point, the conversion shifts as well as scales. Length and mass are simple proportional factors.
