Note: all conversions are exact.All units except the acre are in international units in which 1 inch = 25.4mm exactly. This has been the official definition since 1959.The official definition of the acre is still based on the 'US Survey foot', which was defined as 1200/3937 meters (making the inch 25.4000508..mm). The difference is only a factor of 0.999998 linearly, or 2 parts per million.The calculations here convert between the acre and international units. To convert acre to and from the old 'US Survey' areas, remove the (0.999998)^2 factor

Note: all conversion into and out of the English Fluid section use 231 cubic inches per gallon as the basis. This is accurate to about 7 or 8 significant digits.All other conversions are exact.All units except Acre-Feet are in international units, in which 1 inch = 25.4mm exactly. See notes on "Area" above.For Acre-Feet, the definition is based on the "US Survey foot', which is accounted for by the (0.999998)^3 factor in the equations involving Acre-Feet.

All units except the acre are in international units in which 1 inch = 25.4mm exactly. This has been the official definition since 1959.The official definition of the acre is still based on the 'US Survey foot', which was defined as 1200/3937 meters (making the inch 25.4000508..mm). The difference is only a factor of 0.999998 linearly, or 2 parts per million.The calculations here convert between the acre and international units. To convert acre to and from the old 'US Survey' areas, remove the (0.999998)^2 factor
