Unit converter: every unit at once, exact
Convert length, temperature, area, volume, weight and mass, time, speed, pressure, energy, power, force, data storage, angle, fuel consumption and frequency, plus the engineering groups: heat, fluids, light, electricity, magnetism and radiology. Type a value in any unit and every other unit of its kind updates at once,
1 m in every length unit
Pick a second unit (type "1 m to …") for the formula from one to the other.
Every unit of a kind at once, both ways: type in any box and the rest follow. Exact: each unit comes from its definition (an inch is 0.0254 m, a pound 0.45359237 kg, a US gallon 231 cubic inches), worked out as fractions, and rounded only when shown, to the precision you choose.
