HOW CONVERSION WORKS

Convert through a common base unit.

Most unit conversions first transform the original value into a standard base unit and then convert that base value into the requested destination unit.

Original → Base unit → Target unit

Temperature uses its own conversion formulas because Celsius, Fahrenheit and Kelvin have different zero points.
