Basic math and common sense still apply in countries using the metric system, even if the measurements are different than those in the United States. American travelers to Canada must learn the metric measurements of fuel volume and distance if they want to calculate the mileage for gas in Canada. Fuel is priced by liter, not gallon, in Canada and distance is measured in kilometers. If you know these few basic items, you can roam in Canada without worries about distance or fuel.
Fill up your gas tank at your starting point in Canada.
Keep track of the kilometers you travel until your next fill-up.
Convert the kilometers to miles. The next time you stop at a gas station to fill up your tank, multiply the number kilometers you've traveled since your last fill-up by 0.62.
Convert the fuel consumed: Divide the number of liters by 3.79 to arrive at the number of gallons consumed.
Divide the total mileage by the total number of gallons of fuel consumed. The resulting figure is how many miles per gallon your car is getting in Canada.
