Unit Converter

Convert length, weight, volume, temperature and 8 more unit families in real time, with decimal and binary support for digital storage units.

What it is

Universal Unit Converter is a single tool covering 12 conversion families: length, mass, volume, temperature, area, speed, pressure, energy, power, time, digital storage and cooking. Type a value and the result appears instantly in the other unit, no Enter key or button click required. Every family shows a common conversions table below the result, so you can spot the most-used multiples at a glance. No ads, no sign-up: every calculation runs entirely in your browser.

  • 12 unit families in one tool, no switching pages
  • Live bidirectional conversion, updated as you type
  • Favorites and recent history saved only on your device
