Convert length, weight, and temperature instantly. Auto-convert as you type. Swap units and copy results. Settings saved locally.

Quick Unit Converter — Length • Weight • Temperature is designed for one purpose only: to let you convert everyday units instantly, directly in your browser popup. Whether you need to switch between metres and feet, kilograms and pounds, or Celsius and Fahrenheit, the addon makes it effortless. Type a value, select the units, and see the result update automatically. You can also swap units with a single click and copy the converted result for use anywhere. The addon works fully offline and provides a fast, distraction-free experience with an industrial-style interface — matte black background with amber highlights — making it clear and easy to read even during long work sessions.
