Temperature conversion

Temperature, like many quantities, can be measured in different units, many of which have particular uses. Temperature conversion refers to the process of transforming values measured in one unit to values in another unit. The most widely used scales are those of Kelvin, Celsius, Fahrenheit and Rankine, for which conversion tables are provided below.

Table 1 compares the values for three major reference points in the Kelvin, Celsius, Fahrenheit and Rankine temperature scales.

Table 2 presents the factors required to convert temperatures from any one of those four scales to the other three.
