How to Convert Fuel Consumption Units
To perform a conversion, look up the target unit's conversion factor relative to the base unit (l100km). Below are the exact mathematical formulas for the most common fuel consumption unit pairs:
Miles per Gallon (US) to Liters / 100 Kilometers
L/100km = 235.215 ÷ mpg (US) Liters / 100 Kilometers to Miles per Gallon (US)
mpg (US) = 235.215 ÷ (L/100km) Miles per Gallon (US) to Miles per Gallon (UK)
mpg (UK) = mpg (US) × 1 Kilometers / Liter to Miles per Gallon (US)
mpg (US) = km/L × 1 Fuel Consumption Unit Conversion Charts

Every Fuel Consumption Unit, Explained
Fuel Consumption conversion covers 4 units. Below is a plain-English definition of each one and where you'll actually meet it in daily life.
Liters / 100 Kilometers (L/100km)
Liters per 100 kilometers measures how much fuel a vehicle uses to travel 100 km — lower is better.
Used for: Official fuel-economy ratings in Europe, Asia, and Australia.
Miles per Gallon (US) (mpg (US))
US miles per gallon measures how many miles a vehicle travels per gallon of fuel — higher is better.
Used for: EPA fuel-economy ratings in the United States.
Miles per Gallon (UK) (mpg (UK))
UK miles per gallon uses the larger imperial gallon, so the same car shows a higher UK MPG figure.
Used for: Official fuel-economy ratings in the United Kingdom.
Kilometers / Liter (km/L)
Kilometers per liter measures distance per unit of fuel — higher is better.
Used for: Fuel-economy figures in parts of Asia and South America.
