About Unit Converter
Pick a category, choose the units to convert from and to, and type a value — the result updates instantly. Length, mass, temperature, volume, area, speed, and digital storage are all supported.
Conversions run entirely in your browser using exact factor ratios (and the proper formulas for temperature), so nothing is sent to a server.
