Unit Converter

Unit Converter is a free online tool that converts between metric and imperial units across length, mass, temperature, data, area, volume, speed, and time — type one number and see it in every unit of the category at once.

Data units are shown in both bases: SI (1 KB = 1000 bytes) and binary (1 KiB = 1024 bytes). Temperature conversions use the exact offset formulas, so 32 °F is precisely 0 °C.
