How is Fuel Economy Measured?
In most Asian countries, fuel efficiency is simply measured by how many kilometers a car can run on one liter of fuel (km/L). In Europe, the standard is inverted: they measure how many liters of fuel are required to drive 100 kilometers (L/100km). Meanwhile, the USA and UK measure distance per volume using Miles per Gallon (MPG).
Frequently Asked Questions
Are US MPG and UK MPG the same?
No, they are different! The United Kingdom uses the Imperial Gallon (which is about 4.54 liters), whereas the US uses the US Liquid Gallon (which is about 3.78 liters). Because the UK gallon is larger, a car will have a higher UK MPG rating than a US MPG rating for the same exact fuel efficiency.
