About Unit Converter

Unit Converter handles the everyday categories: length, mass, volume, area, speed, time, data, pressure, energy, angle, and temperature. Enter a value and see it in the unit you want, plus every other unit in that category.

It runs in the page and remembers your last category and units in your own browser.

2. Type a value and pick the from and to units. The swap button flips them.
