This fuel consumption calculator finds your real fuel economy from the fuel used and the distance driven, in L/100km or MPG. Enter both values above.
Formulas
L/100km = Fuel used (L) ÷ Distance (km) × 100 MPG = Distance (mi) ÷ Fuel used (gal)
Example
40 L over 500 km: consumption = 40 ÷ 500 × 100 = 8 L/100km.
