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.

Horsepower has several definitions. The 550 ft-lb and electric are the most common, and are very close numerically. Both are provided here.
Conversions within watt, kilowatt, and Horsepower (electric) and BTUs per hour are exact. Between Horsepower (550 ft-lb) & Foot-lb per sec are also exact
Conversions between two sets of units lsted above are good to 15 or more significant digits.

System memory and flash memory are generally manufactured in power of 2 data quantities, and confrom to the numbers above.
Disk drives are not manufactured in power of 2 data quantities, and are generally measured in base 10, where a megabyte=1,000,000 bytes, and a gigabyte=1,000,000,000 bytes as this allows the marketing department to quote slightly higher numbers.

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 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.
Dry Volumepint (dry)

Conversion to and from liters is accurate to about 6 digits. Each conversion to/from liters uses its own factor from the US Dept of Commerce National Institute of Standards.
