Litres per hundred kilometres (L/100km) is an expression of fuel efficiency used in most European countries. This method of expressing fuel efficiency is quite different than the miles per gallon (MPG) rating used in the United States. You can convert a vehicle's MPG rating to L/100km by using a simple formula. Because the expression is backwards compared to MPG (the variable is the amount of fuel consumed, versus the distance driven), the lower the L/100km rating is, the more fuel efficient the vehicle is.

## Instructions

- 1
Determine the MPG figure you want to convert. If you want to convert a vehicle's EPA rating, visit the EPA's Fuel Economy website to view official ratings.

- 2
Divide 235.215 by the MPG rating you want to convert. For example, if the MPG rating is 30, divide the above number by 30.

- 3
Round the answer to the nearest hundredth. In the 30 MPG example, 7.8405 rounds to 7.84.

- 4
Express the answer as L/100km. For example, 30 MPG converts to 7.84L/100km.

#### Tips and warnings

- The formula used is for U.S. gallons. If you want to convert Imperial MPG to L/100km, divide 282.481 by the MPG rating.
