How to calculate
Calculate measured fuel consumption from a completed trip.
Consumption = fuel/distance*100; Distance per litre = distance/fuel
Worked example
Distance driven (km): 600; Fuel used (litres): 40.
Consumption: 6.67 L/100 km; Distance per litre: 15 km/L.
Assumptions and limits
A consistent fill-to-fill method can help. Different fill levels, driving conditions and measurement errors affect the estimate.
Results are rounded for display; calculations use unrounded values. Read our calculation methodology.
Understanding the result
Lower litres per 100 km means less fuel used for the same distance; higher km/L means better distance per litre.
