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.
What is a US fluid ounce?
Exactly one 128th of a US gallon, which makes it 29.5735295625 ml exactly. The imperial fluid ounce is a different unit at exactly 28.4130625 ml, so a UK recipe calling for 10 fl oz means 284 ml and a US one means 296 ml. It is also a volume, not a weight: an ounce of flour is not a fluid ounce of flour.
How many US fluid ounces are in an imperial pint?
One imperial pint is 19.215199 US fluid ounces. Going the other way, one US fluid ounce is 0.052042137 imperial pints. 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.
