MPG (US) to L/100kmmpg (US) → L/100km
Formula: L/100km ≈ 235.215 ÷ mpg (US)
Formula
L/100km ≈ 235.215 ÷ mpg (US)
Example: 35 mpg (US) = 235.215 ÷ 35 = 6.72042 L/100km
Some units measure the same thing the other way round: L/100km is fuel per distance, while km/L and mpg are distance per fuel. Converting between them divides a constant by the value, so a smaller L/100km means a larger mpg.
