Unit Converter
Fast, lightweight unit converter API for developers. Convert between 100+ units across 10 categories — Length, Weight, Area, Volume, Time, Temperature, Speed, Pressure, Energy, and Data — with a single GET request. Built for easy integration: all units support short aliases (e.g. km, mph, °c, kg, GB) so you can convert meters to feet, Fahrenheit to Celsius, kg to pounds, or bytes to megabytes…
