Gas Mileage Calculator


To get the numbers you require for this calculator: when you fuel up set your vehicle trip meter to zero (or write down your odometer number) and fill the tank to the top. The next time you fuel up write down your trip meter value (or your new odometer reading) and ensure you fill your tank to the top again. Keep your gas receipt as it has your litres filled and price of gas. You then input your kilometers driven (subtract odometer reading if that's what you used), litres of fuel and gas price. It's that easy. Challenge yourself to optimize your efficiency by following our DriveWiser tips and using the mileage calculator.



 

Litres per 100km Miles per Imperial Gallon
Fuel $ to drive 1km Fuel $ to drive 1 mile

1 Imperial gallon = 4.54609188 liters, 64 liters = 14.078 imp gallons 1 mile = 1.609344 kilometers, 880 km = 546.8 miles 546.8/14.078 = 38.84 MPG (imperial) not 32.35 based on 3.78 liters per US gal

Mine isn't that great either but I think that mostly has to do with the cold temps of winter. The mileage decreases for most cars.

Yeah worked fine for me too. If it was wrong before, it's definitely fixed now.

Not sure what you're talking about, it worked fine for me!

The conversion from L/100 km to MPG is still wrong! A Prius, say, has a fuel efficiency rating of 5 L/100 km shows a milage rating of 12 MPG, while a Hummer that rates 20 L/100 km shows 47 mpg.

I try to beat my mileage with each fill up. I'm doing pretty well too. Since I've started thinking about it, I've cut my gas bill by almost 1/3!! It's amazing! Great site btw.

I believe the conversion to mpg is wrong - I calculate it to be 25.51
