Introduction
Fuel Economy Calculator — km/L, MPG and L/100km — three metrics at once. Enter Distance (km), Fuel used (L) to get an instant, accurate result.
Formula
km/L = distance / fuel used. MPG = km/L × 2.35215. L/100km = 100 / (km/L).
Step-by-step
- Enter the Distance (km).
- Enter the Fuel used (L).
- Click Calculate to see your result instantly.
Real-world example
Example: With Distance (km) = 500, Fuel used (L) = 40, the Fuel Economy Calculator gives Km Per L: 12.5, Mpg: 29.4019, L Per 100km: 8.
Frequently Asked Questions
Why are there three different results?
Different regions use different fuel-economy conventions — km/L and L/100km are common outside the US, while MPG is standard in the US.
Which is better, higher or lower L/100km?
Lower — it means less fuel is needed to travel the same distance.
What inputs does the Fuel Economy Calculator need?
You'll need to provide: Distance (km), Fuel used (L). All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.
How accurate is the Fuel Economy Calculator?
The Fuel Economy Calculator applies the formula exactly as calculated — km/L = distance / fuel used. MPG = km/L × 2.35215. L/100km = 100 / (km/L). — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Is the Fuel Economy Calculator free to use?
Yes, the Fuel Economy Calculator is completely free, requires no signup, and runs instantly in your browser.
