Fuel Consumption Calculator
Calculate fuel consumption rate (liters per 100 km or MPG). Enter distance traveled and fuel used to compute consumption efficiency and estimate range on a full tank.
Formula
L/100km = (Fuel Used ÷ Distance) × 100; MPG = 235.214 ÷ L/100km; Range = (Tank Size ÷ Fuel Used) × Distance
- L/100km is the metric standard for fuel consumption
- Lower L/100km = better fuel efficiency
- MPG (Miles Per Gallon) is the US standard
- Range calculation assumes uniform consumption
500 km trip, 50L used, 60L tank
Inputs
- Distance Traveled: 500 km
- Fuel Used: 50 liters
- Full Tank Capacity: 60 liters
(50 ÷ 500) × 100 = 10 L/100km; 235.214 ÷ 10 = 23.5 MPG; Range = (60 ÷ 50) × 500 = 600 km on full tank
Frequently asked questions
What is good fuel consumption?
Less than 6 L/100km is excellent; 6-8 is good; 8-10 is average; over 10 is high.
Why the 235.214 constant?
It's (100 × liters/gallon) ÷ km/mile ≈ 100 × 3.78541 ÷ 1.60934
