Unit converter

Every category has a base unit. The value goes into the base unit and from there into the target one, so any pair of units works the same way.

Temperature is the exception: the scales differ in their zero as well, so °C, °F and K go through degrees Celsius instead of a factor.

The site's engine is a 1:1 port of the Android app's code.
