Unit and currency converters

Lengths, weights, temperatures, pesetas and engine power.

Change units in a second

The unit converter switches instantly between metric and imperial units across six quantities: length, mass, area, volume, speed and temperature. The euro and peseta converters use the official, irrevocable rate of 166.386 pesetas per euro, and the power converters turn kilowatts into metric horsepower (CV/PS) and mechanical horsepower (HP), handy for comparing car and motorbike engines.
