# Unit of Measure

Pronunciation: /ˈju.nɪt ʌv ˈmɛ.ʒər/ Explain

A unit of measure is the definition of the number '1' in a metric space. For example, when we use meters, the unit of measure is 1 meter. In the context of meters, a unit is 1 meter. However, if one is using feet for a measurement of distance, '1' means 1 foot.

A mathematical object is unity if it defines 1 in a unit of measure1.
