What is the Fuel Economy Converter?

MPG (miles per gallon) and L/100km (liters per 100 kilometers) measure fuel economy inversely — higher MPG is more efficient, while lower L/100km is more efficient. This calculator converts between the two.

How to use it

  1. 1 Enter the value.
  2. 2 Choose the conversion direction.

Worked examples

30 MPG to L/100km

30 MPG is about 7.84 L/100km.

Limitations

  • •Uses the US gallon (3.785 L) — UK/imperial gallons differ.

Frequently asked questions

Why is the conversion the same formula both ways?

Because MPG and L/100km are reciprocally related through the same constant (235.214583) — dividing that constant by either value gives the other.
