Frequently Asked Questions

The US gallon is smaller (3.785 L) than the UK gallon (4.546 L), so the same car shows a higher UK MPG figure.

L/100km measures fuel used per distance, so a lower number means better fuel economy, the opposite of MPG.

Divide 235.215 by the L/100km value to get US MPG (282.481 ÷ value for UK MPG).
