What is Unit Converter?
Type a number on either side and the other side updates as you type, across twelve categories from centimetres and pounds to gibibytes, psi and miles per gallon. Factors follow the exact official definitions (an inch is exactly 25.4 mm, a US gallon exactly 3.785411784 litres), and a line under the fields shows the factor or formula for the pair you picked. Temperature and fuel economy aren't simple multiplications, so they use the proper formulas, including the reciprocal jump from L/100 km to mpg. Everything runs in your browser and works offline; nothing you type is uploaded, and only your last category and units are remembered on this device.
