Equals – Unit Converter

Equals turns any measurement into any other – and shows you exactly how.

Type a value, pick two units, and the answer is there. Edit either side and the other one follows. Every result comes with its formula ("Fahrenheit = Celsius × 1.8 + 32"), so you can trust it, learn it, or check your homework.
