## How to Calculate Fuel Consumption in Liters Per 100km

Throughout the world, fuel consumption is most often measured in liters per 100km (L/100km). L/100km is used in places including most of Europe, Canada, Australia, New Zealand, China, South Africa, and some Central American and South American countries. It does not include the US, where miles per gallon (MPG) is the fuel consumption standard in common usage.

To calculate L/100km, start by finding the kilometers per liter (km/L), then convert to liters per 100km.

The formula to find km per liter (km/L) is:

consumption in km/L = distance in km ÷ amount of fuel consumed in L

The fuel consumption in kilometers per liter is equal to the distance traveled, divided by the amount of fuel consumed.

Now, find liters per 100km (L/100km) by dividing 100 by the km per liter (km/L).

consumption in L/100km = 100 ÷ consumption in km/L

For example, let’s find the fuel consumption in L/100km of a vehicle that drives 600 kilometers and uses 50 liters of petrol to drive that distance.

For example, let’s find the fuel consumption in L/100km of a vehicle that drives 600 kilometers and uses 50 liters of petrol to drive that distance.

km/L = 600 ÷ 50
km/L = 12

L/100km = 100 ÷ 12 km/L
L/100km = 8.33

To use the formula above, you will need to find the amount of petrol it takes to drive a specific distance. This can be done using a few simple steps.

Start by completely filling up the tank in your vehicle. Make sure to record the vehicle’s odometer reading before you leave the gas station (or reset your trip odometer to zero).

Then, drive as you normally would until you stop to refuel.

At the gas station, record the new odometer reading (or check the number of km you traveled on the trip odometer). Then, fill up your tank again and record the number of liters it took to do this.

Determine the distance driven by subtracting the previous odometer reading from the current odometer reading (or refer to the reading on the trip odometer).

distance = current odometer – previous odometer

Now, enter the distance driven (in km) and the amount of fuel it took to fill the tank (in liters) into the formulas shown above to find your fuel consumption (in L/100km).
