Factors are exact definitions (1 inch = 0.0254 m, 1 pound = 0.45359237 kg). Month and year use the average calendar length (30.44 and 365.25 days). KB, MB, GB in this tool mean 1024 bytes each, as your operating system shows them; KiB, MiB and GiB are the same value under their exact names. Mach is not offered because it depends on air temperature and altitude, so it has no fixed factor.
How the Unit Converter Works
Pick a category, type a value and the converter shows the result in the unit you choose - and at the same time in every other unit of that category. Ten categories are covered: length, mass, area, volume, temperature, speed, time, data size, pressure and energy. The factors are the exact legal definitions, not rounded approximations: one inch is 0.0254 metres, one pound is 0.45359237 kilograms, one nautical mile is 1852 metres and one calorie is 4.184 joules. Temperature is the one category that is not a simple multiplication: the three scales have different zero points, so the converter first moves the value to Celsius and then to the target scale. That is why 0 degrees Celsius is 32 Fahrenheit, 100 Celsius is 212 Fahrenheit and minus 40 is the same in both. Results show six significant digits - more precision than everyday use needs. Everything is calculated in your browser.
