Fuel Economy Calculator

Litres per 100 kilometres (L/100km) is the accepted method of reporting fuel economy in Canada. Those who are familiar with MPG (miles per gallon) are often confused by L/100km, especially since small numbers are “better” than large numbers, which is the opposite of the MPG system. Here’s a quick-and-easy calculator you can use to determine your own vehicle’s fuel economy in L/100km.

What you’ll need:

  • Distance, in kilometres, traveled between fillups. Use your vehicle’s trip computer, or simply write down the start and end odometer readings and determine the difference.
  • Amount of fuel added during fillup, in litres: don’t simply use the fuel tank capacity or you will underestimate the fuel economy!
