The measure of area used in Great Britain and the USA. The measurements of the English and American acre are slightly different. Both are approximately 4,047 m², which is 40.47 ares (just under 63.5 x 63.5 metres). An acre therefore consists of just under 2.5 acres. This was the term used to describe an area that could be worked with a team in a certain period of time (half day or even day). In terms of meaning and size, the old European measures of area, acre, yoke and acre, are quite similar. See also under area measurements and tons.
I have great respect for the scope and quality of the wein.plus encyclopaedia. It is a unique place to go for crisp, sound information on terms from the world of wine.Dr. Edgar Müller
