Formula
Different countries measure fuel efficiency differently. The US uses Miles per Gallon (MPG), Europe and Australia use Liters per 100km, and Japan uses km/L. Higher MPG or km/L means better efficiency. Lower L/100km means better efficiency.
Worked Example
What Is Fuel Consumption And Its Measurement?
- Fuel efficiency is expressed differently worldwide: MPG (US and Imperial), L/100km, and km/L.
- Higher MPG or km/L values mean better fuel economy.
- Lower L/100km values indicate superior fuel efficiency.
- US gallons are smaller than Imperial gallons, so US MPG numbers are typically lower for the same efficiency.
Accurately converting between these systems is essential for global comparisons and understanding your vehicle's true efficiency. Use our Fuel Consumption Converter to easily translate any value.
You can also calculate changes using our Percentage Calculator or Ratio Calculator.
Frequently Asked Questions
What is good fuel efficiency in MPG?
For cars: 30+ MPG is good, 40+ is excellent. Hybrids get 50+. SUVs and trucks typically get 15-25 MPG. Electric vehicles are measured differently (MPGe).
What is the difference between US MPG and UK MPG?
UK (Imperial) gallons are larger than US gallons (4.546L vs 3.785L). So UK MPG values are higher for the same car. UK MPG = US MPG x 1.201.
Why does Europe use L/100km?
L/100km directly tells you how many liters you need for a 100km trip, making it easy to calculate fuel costs. Lower is better. A car using 6 L/100km needs 6 liters for every 100km driven.
