Convert cubic inch to pint (imperial)

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.

American refrigerators are rated in cubic feet (a 20 cu ft fridge holds about 570 l, and 1 cu ft is 28.3 l), natural gas is metered in hundreds of cubic feet (ccf) and billed in therms, and lorries and moving boxes are sized in cubic feet. Concrete, gravel, mulch and topsoil are ordered by the cubic yard, 27 cu ft or 0.76 m³: 'a yard of concrete'. The cubic inch, 16.4 cm³, is how classic American engines are sized: a 350 cu in V8 is a 5.7-litre engine.
