About Fuel Efficiency Metrics
MPG measures how many miles a vehicle can travel on one gallon of fuel. Higher MPG means better fuel efficiency. This is the standard measurement used in the United States.
L/100km measures how many liters of fuel a vehicle consumes to travel 100 kilometers. Lower L/100km means better fuel efficiency. This is the standard measurement used in Europe and many other countries.
km/L measures how many kilometers a vehicle can travel on one liter of fuel. Higher km/L means better fuel efficiency. This is commonly used in some Asian countries and is the inverse of L/100km.
Frequently Asked Questions
MPG measures distance per fuel unit (higher is better), while L/100km measures fuel used per fixed distance (lower is better).
Divide 235.214 by the MPG value. For example, 30 MPG is approx 7.8 L/100km.
This calculator uses US Gallons. To convert UK Imperial MPG, the formula is slightly different.
Generally, anything above 30 MPG (below 7.8 L/100km) is considered good for a gasoline car. Hybrids often exceed 50 MPG.
Different countries use different standards. Converting helps you compare vehicles when importing or traveling.
Fuel efficiency is a critical factor in vehicle ownership, impacting both running costs and environmental footprint. However, different regions use different metrics, making comparison difficult.
In the US, Miles Per Gallon (MPG) is the standard, focusing on how far you can go. In Europe, Liters per 100km (L/100km) is used, focusing on fuel consumption over a fixed distance.
Converting between these units isn't linear. A small change in L/100km at high efficiency (low numbers) represents a huge change in MPG. Understanding this relationship helps in making better car buying decisions.
Our calculator provides instant, accurate conversions between all major units, ensuring you can compare any vehicle regardless of where it was manufactured or sold.
Conversion Formula:MPG = 235.214 ÷ L/100km | L/100km = 235.214 ÷ MPG | km/L = 100 ÷ L/100km
