What is a cubic inch?

Exactly 16.387064 millilitres, since the inch is exactly 25.4 mm. American engine displacement was quoted in it until the 1980s — a 350 small block is 5.7 litres.

What is an imperial pint?

An eighth of an imperial gallon, 568.26125 ml exactly, and still the legal measure for draught beer and doorstep milk in the UK. A US pint is 473 ml, which is why a British pint glass holds noticeably more.

How many imperial pints are in a cubic inch?

One cubic inch is 0.028837201 imperial pints. Going the other way, one imperial pint is 34.677429 cubic inches. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.
