Enter a value to instantly convert between fuel economy units.
1 MPG (US) = 235.2146 Liters per 100km
Key Formulas
MPG (US) → Liters per 100km
L/100km = mpg × 235.215Liters per 100km → MPG (US)
mpg = L/100km × 235.215Km per Liter → MPG (US)
mpg = km/L × 2.35215MPG (US) → Km per Liter
km/L = mpg × 0.425144Formula
L/100km = 235.214583 ÷ mpgWhen you're shopping for a car imported from Europe, renting a vehicle abroad, or comparing specs on a global model, the fuel economy figures use opposite scales. US ratings go higher-is-better (mpg), while European and Australian stickers go lower-is-better (L/100km). The conversion involves dividing a fixed constant by the mpg value because the two metrics are mathematical inverses of each other.
