How to convert km/L to MPG


I am constantly surprised at how few people take their gas mileage. Even those that "have an idea" are usually just going by what the dealer had told them about their car. The funny part is almost everybody can tell me how many km they get to a tank, and how much it costs to fill, but they never know how many liters nor gallons they put in. If you know the price of gas it is easy to divide the cost by the price to get the liters or gallons. Even easier is to just check the pump when you fill up.

Zero your trip meter when you fill up and check how many liters you put in. Now the next time you fill up do the same thing and you will have the previous trip reeding, in Canada here it will be KM, and you can simply divide that by the Liters you just put in. This gives you Kilometers per liter of fuel. Everything I see on TV and the internet is the american standard of Miles per Gallon. So I convert KM/L into Miles Per Gallon simply by multiplying it by 2.825.

For example, I used to run my 240 liter tank empty at 800km. 800km divided by 240 liters equals 3.33km/liter. Now 3.33 multiplied by 2.825 equals 9.42mpg. Hope this helps more people keep track of their mileage.
