A furlong is a measure of distance in imperial units and U.S. customary units equal to one-eighth of a mile, equivalent to 660 feet, 220 yards, 40 rods, or 10 chains. Using the international definition of the inch as exactly 25.4 millimetres, one furlong is 201.168 metres.
(in3). 1 acre is defined as 1 chain * 1 furlong. A â¦furlong is 10 chains. 1 chain is 22 yards, or 66 ft, or 792 inches. 1 acre = 1 chain * 1 furlong = 1 chain * 10 chains = 792 in * 7920 in = 6,272,640 in2 1 inch of rain over 6,272,640 square inches of area equals 6,272,640 in3. Now, divide that by the number of cubic inches in a gallon 6,272,640 in3 / 231 in3/gal = 27,154.2857 gallons By comparison, the metric system is much easier. 1 mm of rain over 1 hectare (=10,000 m2) means 10,000 L/ha (litres per hectare).
