ACRE, the universal measure of land in Britain. An acre in England contains 4 square roods, a rood 40
perches or poles of 16 feet each by statute. Yet this measure does not prevail in all parts of England, as the length of the pole varies in different counties, and is called customary measure, the difference running from the 16 feet to 28. The acre is also divided into 10 square chains, of 22 yards each, that is 4840 square yards. An acre in Scotland contains 4 square roods; 1 square rood is 40 square falls; 1 square fall, 36 square ells; 1 square ell, 9 square feet, and 73 square inches; 1 square foot, 144 square inches. The Scots acre is also divided into 10 square chains; the measuring chain should be 24 ells in length, divided into 100 links, each link 8 inches; and so 1 square chain will contain 10,000 square links.
The English statute acre is about 3 roods and 6 falls standard measure of Scotland.
