Measured fuel economy

Calculate consumption from distance traveled and fuel used.

How this works

L/100 km = fuel/distance × 100; mpg converts kilometers and liters to the selected gallon definition.

Example

Using the example inputs, measured consumption is 7 L/100 km.

Distance since fill
500 km
Fuel used
35 L
Measured consumption
7 L/100 km

Scope and assumptions

Use comparable full-tank readings; dashboard and fill-level errors affect results.
