About unit conversion
This tool uses standard international conversion factors across eight categories — length, temperature, weight, area, volume, speed, storage, and power. Enter a value to see results for every unit at once, all computed locally in your browser.
Note· Temperature (Celsius/Fahrenheit/Kelvin) is an affine transform with an offset. Results keep 10 significant digits, and very large or small values use scientific notation.
