Not really.
US gallon is 8 pints, UK gallon is 9.608 pints
Conversion factor is 1.201 - so 92 miles per US gallon is 110.5 miles per UK gallon
Actually - to be precise a UK gallon is also 8 pints, but they are UK pints. Its just that a US pint has 16 US Fluid Ounces and a UK pint has 20 Fluid Ounces. Then you have to take into account that the US Fluid Ounce is 0.9608 of a UK Fluid Ounce! That is what makes the conversion factor to be 1.201 :-
That makes a US Gallon (16/20)/0.9608 (or 0.8326) the size of a UK gallon. Therefore 92 US Mpg = 92*(20/16)*0.9608 = 110.5 UK Mpg
Jus' sayin'!!
