How to convert
L/100 km = 235.215 ÷ MPG (US). MPG (US) = 235.215 ÷ L/100 km. Example: 30 MPG is about 7.84 L/100 km. For UK gallons use 282.481 instead of 235.215.
Good to know
- A UK (imperial) gallon is bigger than a US gallon (4.546 L against 3.785 L), so the same car shows a MPG figure about 20% higher in UK gallons. Make sure you pick the right one.
