A magnitude is often compared with an specific magnitude value in order to take a decision. Or computed using factors. These values or factors can be constants (like the gravity or the speed of light) or can be configurable.
Historically, the study of a system to determine the values to tune its behaviour has been called “system calibration”. Due to lenguage abuse these configurations values have been called “calibrable values” or simply, a “calibration”.
As they are values, they need a conversion between the physical value and the raw value representations.
