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 an imperial gallon?
Exactly 4.54609 liters since 1985, and the reason UK and US fuel economy figures cannot be compared: it is 20% larger than the US gallon, so 40 mpg in Britain is about 33 mpg in America on the same car.
How many imperial gallons are in an imperial gill?
