SiteCheck
Convert a value between units of length, area, volume (US customary and metric, cooking measures), mass, speed, pressure, energy, power, data size (SI and binary), time and temperature. Factors are exact to the definitions in NIST SP 811 (international inch and pound, US gallon, calorie IT, Btu IT, mechanical horsepower). An unknown unit is a 400 that lists every supported unit. Pure code, no outside source.
