Context values
Some unit families need one extra value for a physically accurate result.
Liters per 100 kilometers fuel economy unit.
Normalize fuel economy to distance per volume, inverting consumption units when needed.
Fuel economy supports both distance-per-volume and volume-per-distance units.
What Fuel Economy conversions measure
Fuel Economy conversions cover units such as miles per gallon, liters per 100 km, and km per liter. Converting between them lets you move between the different measurement systems and conventions used across regions and industries.
Common real-world use
Common real-world uses include car buying and reviews, international vehicle comparison, and fuel cost estimation.
Choosing a unit
Pick the unit your source data, audience, or regional convention already uses, and convert once at the start of a calculation rather than mixing systems partway through.

About Fuel Economy Conversion
Fuel economy units express how far a vehicle travels per unit of fuel (miles per gallon, kilometers per liter) or how much fuel it consumes per unit of distance (liters per 100 kilometers). These are reciprocal relationships, not a simple ratio: converting between a distance-per-volume unit and a volume-per-distance unit requires inverting the value, which this converter and its underlying math handle directly. Common uses include comparing vehicles across US and international fuel-economy conventions, and estimating fuel costs for a given distance.
Quick Facts
- US standard: miles per gallon (mpg)
- International standard: liters per 100 kilometers (L/100 km) and kilometers per liter (km/L)
- Higher mpg means better efficiency; lower L/100 km means better efficiency - the two scales run in opposite directions
- Common uses
- Vehicle shopping and fuel-cost estimation
- Comparing US-market and international-market vehicle specifications
- Trip fuel-cost planning
Conversion Formulas
- Miles per US gallon to Liters per 100 km: divide 235.215 by the mpg value
- Liters per 100 km to Miles per US gallon: divide 235.215 by the L/100km value
- Miles per US gallon to Kilometers per liter: multiply by 0.425144
- Kilometers per liter to Miles per US gallon: multiply by 2.35215
- These are reciprocal relationships for the distance-per-volume vs. volume-per-distance pairs, not simple multiplication - the converter above applies the correct direction automatically
