Anker (unit)

For other uses, see Dutch units of measurement § Volume.

An Anker (usually anglicized as Anchor[1]) was a Dutch unit of capacity for wine or brandy equal to 10 US gallons[2] that was used as a standard liquid measurement.[3] It was most commonly used in Colonial times in New York and New Jersey, thanks to the earlier Dutch settlement of New Amsterdam (later New York City).

Many European countries had a different measurement of this unit that varied from 9 to 11 US gallons [equivalent to 7.5 to 9.25 Imperial gallons[4] or 34 to 42 Litres].[5][6]
