How Liters per 100 Kilometers Calculator Works
This tool works by dividing the liters of fuel used by the kilometers driven and multiplying by 100.
- Step 1
Fill up and reset
Fill the tank fully and reset the trip meter to 0 km.
- Step 2
Drive a full stint
Drive at least 300 km (186 mi) or half a tank for a stable figure.
- Step 3
Refill and record
Refill to full and note liters added and kilometers driven.
- Step 4
Read L/100 km
The calculator shows liters per 100 kilometers (L/100 km) with MPG and km/L equivalents.
Liters per 100 Kilometers Calculator Formula
The formula divides liters by kilometers and multiplies by 100.
L/100 km = Liters Used ÷ Kilometers Driven × 100
US MPG = 235.215 ÷ L/100 km
- Liters Used
- = fuel added at the second fill-up
- Kilometers Driven
- = trip distance between fill-ups
Worked Example
- A driver in Canada adds 46.2 liters after driving 612 km (380 mi).
- L/100 km = 46.2 ÷ 612 × 100 = 7.55 L/100 km.
- US MPG = 235.215 ÷ 7.55 = 31.2 MPG.
- Lower L/100 km figures mean better fuel economy.

The table is a lookup grid of L/100 km values for common combinations of liters used and kilometers driven.
| Liters Used | 300 km | 400 km | 500 km | 600 km | 700 km | 800 km |
|---|---|---|---|---|---|---|
| 20 L (5.3 gal) | 6.7 | 5.0 | 4.0 | 3.3 | 2.9 | 2.5 |
| 30 L (7.9 gal) | 10.0 | 7.5 | 6.0 | 5.0 | 4.3 | 3.8 |
| 40 L (10.6 gal) | 13.3 | 10.0 | 8.0 | 6.7 | 5.7 | 5.0 |
| 50 L (13.2 gal) | 16.7 | 12.5 | 10.0 | 8.3 | 7.1 | 6.3 |
| 60 L (15.9 gal) | 20.0 | 15.0 | 12.0 | 10.0 | 8.6 | 7.5 |
| 70 L (18.5 gal) | 23.3 | 17.5 | 14.0 | 11.7 | 10.0 | 8.8 |
What is a Liters per 100 Kilometers Calculator?
A Liters per 100 Kilometers Calculator is a metric fuel consumption tool that calculates how many liters a vehicle burns every 100 kilometers.
L/100 km is the fuel economy standard in Canada, Europe, Australia, and most of the world. The unit measures consumption, not distance per unit of fuel, so a lower number is better. The Liters per 100 Kilometers Calculator gives the figure from a real fill-up.
L/100 km scales linearly with fuel used, which makes cost math simple: L/100 km × price per liter = cost per 100 km.
What are the uses of a Liters per 100 Kilometers Calculator?
There are 4 main uses of the Liters per 100 Kilometers Calculator, including metric economy checks, cost per 100 km, and vehicle comparison.
Measure real consumption
Compare real L/100 km with the official rating.
Price 100 km of driving
