What is an imperial gill?
A quarter of an imperial pint, 142.0653125 ml exactly. It survives as the measure spirits were once poured by in British pubs, and in old recipes that ask for a gill of cream.
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.
