Abbreviation (noun) · /ˌem.piːˈdʒiː/

Definition

Miles per gallon — a measure of a vehicle's fuel efficiency indicating how many miles a vehicle can travel on one gallon of fuel; in the UK, typically stated as imperial miles per imperial gallon (4.546 litres); in the US, miles per US gallon (3.785 litres).

Origin

An abbreviation of miles per gallon, combining mile (from Old English mīl, from Latin milia passuum: a thousand paces), per (from Latin per: through, by means of), and gallon (from Old French jalon, of uncertain further origin, possibly from Medieval Latin galleta). The abbreviation being used from the early days of motoring to describe fuel efficiency. The UK mpg figure being higher than an equivalent vehicle's US mpg figure because the imperial gallon is larger than the US gallon — an important point of confusion in international fuel efficiency comparisons.
