About the fuel economy category
How far a vehicle goes per unit of fuel: consumption and efficiency.
You will reach for these conversions when comparing a US car (mpg) with a European one (L/100 km), or understanding why lower L/100 km but higher mpg both mean better efficiency.
- An efficient compact: 7 L/100 km is about 33.6 US mpg
- A US average car: 30 mpg is about 7.8 L/100 km
Popular fuel economy conversions
Common mistakes
- US vs UK mpg: UK gallons are bigger, so UK mpg figures are about 20% higher for the same car
- mpg is inverse: doubling mpg halves fuel use, but the savings are not linear in the way people expect
