Definição
Unidade de volume com duas definições: o galão americano equivale a 3,785411784 litros; o galão imperial (britânico) equivale a 4,54609 litros.
Explicação
The US gallon is about 20% smaller than the UK imperial gallon — a critical distinction for fuel economy comparisons. US fuel efficiency is measured in miles per gallon (mpg); a car getting 30 US mpg achieves only about 25 UK mpg. One US gallon = 4 quarts = 8 pints = 128 US fluid ounces. US gas prices per gallon are roughly one-quarter of European per-liter prices before unit conversion.
