For example, if your car gets 30 mpg, it will travel 30 miles on one gallon of petrol. To find out how many liters you get per mile, you can divide the number of miles per gallon by the number of liters in one gallon. There are approximately 3.785 liters in one gallon.
So, if your car gets 30 mpg, you can get approximately 30 / 3.785 = 7.9 liters per mile.
However, the actual fuel efficiency of your car may vary depending on factors such as traffic conditions, driving speed, and the terrain.
