The conversion of temperature units is different from most other unit conversions, because it is not multiplicative. This is simply because the zeros of various systems are set at different values. For example, zero degrees Centigrade is the same as
This converts the temperature. Convert only converts the units of temperature.
In:= ConvertTemperature[20, Fahrenheit,
To organize the use of units, certain standardized systems have been developed. These include the International System (SI) and systems using particular metric units, such as the meter/kilogram/second system. The functions SI, MKS, and CGS convert various units into the standard systems.
The International Standard unit for pressure is the Pascal.
