Electricity, light and radiation
Pick a measurement or one of the popular conversions below. Every converter works in both directions, shows the formula and the exact factor, converts a value into every unit of its kind at once and understands values such as 5′11″ or 12 lb 3 oz. All units are grouped by what they measure – length, mass, temperature, area, volume, speed, time, pressure, energy, power, data, fuel economy, electricity, light and radiation – because only units of the same kind can be converted into each other.
Everything is calculated in your browser with the official definitions of each unit (for example 1 inch = 25.4 mm and 1 pound = 0.45359237 kg exactly); nothing you type is sent anywhere.
