# System of measurement

A system of measurement is a set of related measures that are used to give a numeric value to something. A "system of measurement" is also known as a "metric".[1] There are many systems of measurement. Some systems of measurement describe physical systems. Other systems of measurement describe economic systems.[2]

The term "system of measurement" is often used in engineering application to describe a set of operational devices that take measurements.[3]

In metrology, the term "system of measurement" is often used as a synonym for system of units.[4] The international standard system is the International System of Units. Other systems in common use are the closely related United States customary units and British imperial units.

A system of measurement that describes economic systems is called an econometric system.[5] An econometric system uses quantities such as Gross domestic product and money supply to model an economic system.[6][2]
