{{DISPLAYTITLE:English units}}

'''English units''' are the historical [[units of measurement]] used in [[England]] up to 1824, which evolved as a combination of the [[Anglo-Saxons|Anglo-Saxon]] and [[Ancient Roman units of measurement|Roman]] systems of units. Various standards have applied to English units at different times, in different places, and for different applications. The units were redefined in the [[United Kingdom]] in 1824 by a [[Weights and Measures Acts of the United Kingdom|Weights and Measures Act]], which retained many but not all of the unit names and redefined some of the definitions.
