A dry gallon was never defined in the statutes authorizing the United States customary units of capacity. However, by implication, for comparison with other gallon-size units, it is sometimes assumed that the corn gallon of the Traditional British units of capacity was carried over as the United States dry gallon, and on this basis, the units of capacity such as the pint, quart, and bushel were determined. This United States dry gallon has the value of 4 (dry) qt or 268.8025 cu in, or 4.404884 L.
