The process of measurement involves estimating the ratio of the magnitude of a quantity to the magnitude of a unit of the same type (length, time, mass, etc.). A measurement is the result of such a process, expressed as the product of a real number and a unit, where the real number is the estimated ratio. An example is 9 metres, which is an estimate of an object's length relative to a unit of length, the metre. Unlike a count, or integer quantity of items that is known exactly, every measurement is an estimate that has some uncertainty.

A measurement is a comparison to a standard. -- William Shockley

By number we understand not so much a multitude of Unities, as the abstracted Ratio of any Quantity to another Quantity of the same kind, which we take for Unity. -- Sir Isaac Newton (1728)
