ConvertLab

Unit Converter

A free unit converter for length, weight, volume, and temperature. Linear measurements convert through a base unit using exact constants — one inch is defined as 0.0254 metres, one pound as 453.59237 grams — while temperature is converted through Celsius so its offset is handled correctly. Everything runs in your browser. The factors are fixed reference values, so the same input always returns the same result; nothing is uploaded or stored.
