# Measurement

Pronunciation: /ˈmɛʒ.ər.mənt/ Explain

Measurement is assigning a number to a location based upon a unit of measure. For example, if one is using the metric system of distance, the unit of measure is 1 meter. A measure of 2 meters is twice as long as a measure of 1 meter. A measure of 0.5 meters is half as long as a measure of 1 meter.

Common measurements include distance, time, mass, energy, force and angle.

A metric space is a geometric space with a method of measurement assigned to the space.

Measurement error is an important consideration. When measuring with any device, one is approximating the measure. For example, if the length of a piece of paper is measured with a metric ruler, typically the measurement is accurate to only 1 millimeter. Since the measurement is not mathematically exact, it introduces an error.
