Metrology

Metrology has its roots in the French Revolution, with the political motivation to harmonize units all over France and the concept of establishing units of measurement based on constants of nature. The earliest forms of metrology were simply arbitrary standards set up by regional or local authorities, often based on practical measures such as the length of an arm or parts thereof. Though metrology is the science of measurement, in practical applications, it is the enforcement and validation of predefined standards. Theoretically, metrology, as the science of measurement, attempts to validate the data obtained from test equipment. At the base of metrology is the definition, realisation and dissimination of units of measurement.
