Convert between units across eight categories — length, weight, temperature, volume, area, speed, data, and time. Pick a category, choose the units to convert from and to, and the result updates instantly. It handles metric and imperial units and the special math for temperature. Everything runs in your browser.

How to use

  1. Choose a category such as Length or Temperature.
  2. Select the From and To units and enter a value.
  3. Read or copy the converted result; use Swap to reverse.

How it works

Most units convert through a common base unit for their category — for example every length is expressed in meters, then scaled to the target unit. This keeps conversions consistent and accurate. Temperature is handled separately because Celsius, Fahrenheit, and Kelvin don't share a simple multiplier; values are converted via Celsius using the proper formulas.
