This converter handles nine common unit categories - length, weight, temperature, volume, area, speed, pressure, data storage, and time - and updates the result instantly as you type, entirely in your browser. Most categories convert by a fixed ratio to a base unit (like meters for length or bytes for data), except temperature, which needs its own formula since 0°C isn't 0°F or 0 K.
