How conversions work
Each unit is stored as a fixed multiple of one standard unit, such as the meter for length. To convert, the value is turned into the standard unit and then into the unit you want. Temperature is the exception, because Celsius, Fahrenheit and Kelvin do not start at the same zero.
US gallons, quarts, pints and cups are used for volume. Results show up to 8 significant digits.
