Overview

The Fuel Economy Calculator computes your vehicle's fuel efficiency (km/L or MPG) from the distance traveled and fuel consumed. Use it to compare city vs. highway driving, track changes over time, and plan your fuel budget.

Formula

Fuel Economy (km/L) = Distance Traveled (km) / Fuel Used (L). For example, driving 500 km on 40 L gives 500 / 40 = 12.5 km/L.

How to Use

  1. 1Enter the distance traveled in kilometers (use the trip odometer for accuracy).
  2. 2Enter the amount of fuel consumed in liters.
  3. 3Click 'Calculate' to see your fuel economy in km/L.
  4. 4Optionally enter fuel price per liter to see cost per kilometer.

Tips

  • For the most accurate reading, fill the tank completely and measure until the next full fill-up.
  • Reducing aggressive acceleration and braking can improve fuel economy by 10–15%.
  • Keep tires inflated to the recommended pressure (usually 32–35 psi).
  • Using air conditioning in city driving can reduce fuel economy by about 10%.
  • Track fuel economy over multiple fill-ups for a more reliable average.

FAQ

Q. Why is my real-world fuel economy lower than the official rating?

Official ratings are measured under standardized lab conditions. Real-world factors like traffic, weather, and driving style typically reduce economy by 10–20%.

Q. Is city or highway fuel economy better?

Conventional vehicles are more efficient on the highway. Hybrids and EVs can be more efficient in the city thanks to regenerative braking.

Q. How do I convert km/L to L/100 km?

L/100 km = 100 / (km/L). For example, 12 km/L equals 100 / 12 ≈ 8.33 L/100 km.
