How to convert liters per 100 kilometers to miles per US gallon
Formula, method and accuracy
1 liter per 100 kilometers approximately equals 235.21458333333333333 miles per US gallon.
Divide the exact reciprocal constant 112903/480 by the L/100 km value. A zero source value is undefined because reciprocal fuel-economy formats cannot divide by zero.
Exact ratio: mpg (US) = 112903 / 480 ÷ L/100 km
Decimal form: mpg (US) ≈ 235.21458333333333333 ÷ L/100 km
235.21458333333333333 ÷ 1 ≈ 235.21458333333333333 mpg (US)

About Liters per 100 kilometers and Miles per US gallon
Liters per 100 kilometers measure fuel consumed over distance; US mpg measures distance traveled per US gallon. The two formats are reciprocal.
Liter per 100 Kilometers as the source, Mile per US Gallon as the result
Use this direction when a vehicle consumption figure in liters per 100 kilometers must be compared with a US fuel-economy label, owner report, buying guide, or mileage reference in US mpg.
Result unit
Mile per US Gallon mpg (US)
Mile per US Gallon is a unit used to measure fuel economy.
One mile per US gallon approximately equals 0.4251437074302720034 kilometers per liter.
Where L/100 km-to-US-mpg conversion is useful
This direction helps compare imported vehicle specifications, fuel-economy labels, ownership costs, fleet reports, and real-world consumption records across metric and US formats.
Lower consumption corresponds to higher mileage
This is a reciprocal conversion: decreasing liters used per 100 kilometers increases miles traveled per gallon. The exact reciprocal constant is divided by the source value rather than multiplied by it.
US and Imperial gallons produce different mpg values
This page returns miles per US gallon. An Imperial gallon has a different volume, so an Imperial-mpg comparison must use the separately labeled unit.
How this conversion is verified
The reviewed liter, kilometer, statute-mile, and US-gallon definitions establish the exact reciprocal relationship. The converter applies it consistently to the live value and reference table.
Because the relationship is reciprocal, equal changes in L/100 km do not produce equal changes in mpg. Use the calculator or table instead of a fixed multiplier.
This conversion changes fuel-economy notation; it does not predict actual consumption, which depends on vehicle, route, load, weather, and driving conditions.
Frequently asked questions
6 answers for this conversion
- How do I convert L/100 km to US mpg?
- Divide the exact reciprocal constant 112903/480 by the liters-per-100-kilometers value.
- Why is L/100 km-to-mpg a reciprocal conversion?
- L/100 km measures fuel used per distance, while mpg measures distance traveled per fuel volume. Their numerator and denominator roles are reversed.
- Does a lower L/100 km value mean better fuel economy?
- Yes. Lower consumption means less fuel is used for the same distance, which corresponds to a higher mpg result.
- Does this page calculate US or Imperial mpg?
- It calculates miles per US gallon. Select Mile per Imperial Gallon for the Imperial convention.
- Why is zero L/100 km undefined in mpg?
- The formula divides by the L/100 km value. Division by zero is undefined, so the converter does not return a finite mpg value.
- Can I multiply L/100 km by one fixed mpg factor?
- No. This relationship is reciprocal, not linear. The exact constant must be divided by the source value.
