How to convert liters per 100 kilometers to miles per imperial gallon
Formula, method and accuracy
1 liter per 100 kilometers approximately equals 282.480936332 miles per imperial gallon.
For an approximate imperial-MPG result, divide 282.480936332 by the L/100 km value. The converter uses the exact relationship in the precision details. Zero is undefined because the formula would divide by zero.
mpg (Imp) ≈ 282.480936332 ÷ L/100 km
282.480936332 ÷ 1 ≈ 282.480936332 mpg (Imp)
Exact relationship and precision
mpg (Imp) = 56826125 / 201168 ÷ L/100 km
The converter uses the exact relationship. Display rounding does not change the calculation.

About Liters per 100 kilometers and Miles per imperial gallon
Liters per 100 kilometers measures fuel consumed over a fixed distance; imperial MPG measures distance per imperial gallon. Their relationship is reciprocal.
Liter per 100 Kilometers as the source, Mile per Imperial Gallon as the result
Use this direction when a metric consumption figure must be compared with a UK or historical vehicle rating expressed in miles per imperial gallon.
Result unit
Mile per Imperial Gallon mpg (Imp)
Mile per Imperial Gallon is a unit used to measure fuel economy.
One mile per imperial gallon approximately equals 0.354006189935 kilometers per liter.
Where L/100 km-to-imperial-MPG conversion is useful
This direction helps compare European or metric vehicle specifications with UK mileage figures, interpret imported listings, review older documentation, and translate trip-computer consumption into imperial MPG.
Lower consumption becomes higher mileage
L/100 km and imperial MPG face opposite directions: lower fuel consumption corresponds to higher mileage. The conversion therefore divides an exact constant by the source value rather than multiplying by one fixed factor.
Imperial MPG is not US MPG
This target uses the imperial gallon. The US liquid gallon is smaller, so the same vehicle efficiency has different numerical US and imperial MPG values. Keep the gallon convention explicit.

The reviewed liter, kilometer, statute-mile, and imperial-gallon definitions establish the exact reciprocal constant. The converter uses it for the live result and each table entry.
Standards used for this conversion
- NIST: Handbook 44, Appendix C: General Tables of UnitsThe liter, kilometer, statute-mile, and gallon relationships used by the formula.
- UK Government: Weights and Measures Act 1985The statutory imperial-gallon definition.
- NIST: Writing with SI (Metric System) UnitsRounding guidance for converted measurements.
A unit conversion does not reconcile different vehicle test cycles. Compare ratings only after confirming that their test basis and operating assumptions are compatible.
There is no constant number of imperial MPG gained for each 1 L/100 km reduction because the relationship is inverse.
Frequently asked questions
6 answers for this conversion
- How do I convert L/100 km to imperial MPG?
- Divide approximately 282.480936332 by the L/100 km value. The converter keeps the exact relationship before rounding the imperial-MPG result.
- Does lower L/100 km mean higher imperial MPG?
- Yes. Lower consumption means less fuel is used over 100 kilometers, which corresponds to traveling farther per imperial gallon.
- Why is the conversion reciprocal?
- L/100 km measures fuel volume per distance, while imperial MPG measures distance per fuel volume. Reversing numerator and denominator creates an inverse relationship.
- Is imperial MPG the same as US MPG?
- No. The imperial and US gallons have different volumes, so the resulting MPG figures differ even when vehicle efficiency is unchanged.
- Why can zero L/100 km not be converted?
- The reciprocal formula divides by the L/100 km value. Zero would require division by zero and therefore has no finite imperial-MPG result.
- Does this conversion predict real fuel consumption?
- No. It translates a stated rating between unit formats. Actual consumption depends on the vehicle, route, load, weather, driving, and test conditions.
