How do I convert mpg to l/100km?
Divide 235.2 by the mpg figure. 32 US mpg is about 7.4 l/100km — the standard measure in Europe and Canada.
Calculate fuel cost for any trip based on distance, MPG, and gas price. Compare costs between vehicles and find ways to save on fuel.
Fuel needed = distance ÷ efficiency (mpg or km/l). Trip cost = fuel needed × price per unit. Cost per mile = price ÷ mpg.
A 450-mile trip at 32 mpg needs 14.1 gallons. At $3.60 a gallon that is $50.63, or 11.3 cents per mile.
Divide 235.2 by the mpg figure. 32 US mpg is about 7.4 l/100km — the standard measure in Europe and Canada.
Speed and aggressive driving. Above about 55 mph, consumption climbs sharply from aerodynamic drag, and hard acceleration can add 15–30% in city traffic.
Use cost per mile. At 3.5 miles per kWh and $0.15/kWh, an EV runs about 4.3 cents per mile — roughly a third of a 32 mpg petrol car at $3.60.
