Definition of Measurement
Measurement is the process or the result of determining the ratio of a physical quantity, such as a length, time, temperature etc., to a unit of measurement, such as the meter, second or degree Celsius. The science of measurement is called metrology.
The English word measurement originates from the Latin mēnsūra and the verb metiri through the Middle French mesure.
