Convert gallon (imperial) to Imperial bushel

The UK and the US kept different gallons after 1824. The imperial gallon is 4.546 l and the US gallon 3.785 l, so a US gallon is only five-sixths of a British one; the same applies to their quarts and pints, and a British pint of beer (568 ml, 20 fl oz) is bigger than an American one (473 ml, 16 fl oz). The US also has a separate dry gallon of 4.405 l for grain and produce. Fuel is sold by the litre in Britain today but by the US gallon in America, which matters for fuel-economy figures.

The bushel is a grain measure, 35.24 l in the US and 36.37 l in the imperial system, and US commodity markets still trade wheat, corn and soybeans by the bushel, taken as 60 lb of wheat or 56 lb of corn. The cord is firewood: a stack 4 ft high, 4 ft deep and 8 ft long, 128 cubic feet or 3.62 m³. The acre-foot, the water needed to cover an acre a foot deep (1,233 m³), is the unit of reservoirs and water rights in the western US.
