How it’s calculated
Multiply km/L by 2.3521 for US mpg, or by 2.8248 for UK (imperial) mpg. The UK figure is higher for the same car because the imperial gallon is bigger.
1 km/L ≈ 2.3521458 mpg (US) · 1 mpg (US) ≈ 0.42514371 km/L
mpg (US) = km/L × 2.352145833
- Multiply the value in kilometres per litre by 2.352145833.
- To go back, divide by 2.352145833 (or multiply by 0.4251437074).
- 1 km/L = 2.352145833 mpg (US) · 1 mpg (US) = 0.4251437074 km/L
