English unit

English unit is the American name for a unit in one of a number of systems of units of measurement, some obsolete, and some still in use. In spite of the name, it does not necessarily refer to the (non-SI) system of units still in widespread, but mostly unofficial, use in England and the rest of the United Kingdom. The system is known as the English System in the United States and elsewhere as the Imperial System. The American term 'English unit' includes the Imperial units as well as various other U.S. units such as the U.S. gallon (Queen Anne's wine gallon) and the U.S. bushel (Winchester bushel).
