Unit Converter

Convert between all common units in 8 categories instantly. Enter a value, pick a unit, and see everything at once.

This unit converter covers eight everyday categories — length, weight, temperature, area, volume, speed, data storage, and time — with unit lists that range from millimeters and light-years to bytes and gigabytes. Type a value, choose your starting unit, and every other unit in that category updates instantly in a single results list, so you can compare kilometers to miles or Celsius to Fahrenheit without switching screens. Each result includes a one-click copy button, and the tool remembers your last-used category and unit between visits using your browser's local storage. It's built for students checking homework, cooks converting recipe measurements, travelers working out distances, and developers converting file sizes — anyone who needs a fast, reliable unit conversion tool without ads or unnecessary steps.
