Convert between various units of fuel consumption, including miles per gallon (MPG), liters per 100 kilometers (L/100km), kilometers per liter (km/L), and more.
MPG to L/100km
L/100km to MPG
km/L to L/100km
MPG to km/L
Bar length represents relative fuel efficiency (longer = better)
Note that L/100km is inversely related to MPG and km/L:
Higher MPG or km/L = Better Efficiency
You want these values to be higher
Lower L/100km = Better Efficiency
You want these values to be lower
A car with 30 MPG driving 300 miles would require 10 gallons of fuel. At $3.50/gallon, the fuel cost would be $35.00.
A vehicle rated at 7 L/100km compared to one at 10 L/100km would save 3L of fuel every 100km, or approximately 30% in fuel costs.
A 5 MPG improvement (from 25 to 30 MPG) in a vehicle driven 12,000 miles annually reduces CO₂ emissions by approximately 1 ton per year.
A company fleet of 50 vehicles improving from 8.5 L/100km to 7.5 L/100km could save approximately 5,000L of fuel annually over 100,000km total distance.
U.S. CAFE standards target approximately 49 MPG (4.8 L/100km) by 2026, while EU regulations aim for 3.6 L/100km (65 MPG) by 2030.
A hybrid vehicle achieving 50 MPG compared to its conventional 30 MPG counterpart reduces fuel consumption by 40% for the same distance traveled.
Fuel consumption measures how efficiently a vehicle uses fuel to travel a given distance. Different countries and regions use different units to express this efficiency.
Fuel consumption measures how efficiently a vehicle uses fuel to travel a given distance. Different countries and regions use different units to express this efficiency.
Used in the United States and the United Kingdom, MPG measures how many miles a vehicle can travel on one gallon of fuel. Higher MPG indicates better fuel efficiency.
The standard in most European and many other countries. It measures the amount of fuel consumed to travel 100 kilometers. Lower L/100km indicates better fuel efficiency.
Common in Japan, India, and other countries. Similar to MPG, it measures distance traveled per unit of fuel. Higher values indicate better efficiency.
A less common unit that measures how many miles a vehicle can travel on one liter of fuel.
The inverse of MPG, sometimes used for comparative analyses. Lower values indicate better efficiency.
