Converting fuel efficiency between different measurement systems is a daily necessity when comparing imported vehicles, studying technical manuals, or planning international trips. With ConvertUs, you can perform this conversion quickly, accurately, and reliably, without the need for complex manual formulas.
While km/L is widely used in Latin America and Asia, the L/100km standard is common in Europe, and MPG (miles per gallon) is the norm in the US and the UK. Understanding the relationship between these units prevents interpretation errors and ensures you choose the most efficient vehicle.
Efficiency Converter
Convert between km/L, L/100km, and MPG with absolute precision.

📌 Technical Note: While km/L and MPG are measures of **distance per volume**, L/100km is a measure of **volume per distance**. The calculation uses the $100 / x$ mathematical inversion for these transitions.
The Mathematics of Energy Efficiency
Fuel efficiency conversion follows a well-defined mathematical relationship, although it varies between direct systems (higher is better, like km/L) and inverse systems (lower is better, like L/100km). For instance, 1 km/L is approximately 2.352 MPG in the US.
ConvertUs uses standardized and validated conversion factors, including the critical distinction between the US gallon and the UK Imperial gallon. Our system automatically adjusts the logic for inverse calculations, offering clear and consistent results for automotive engineering, logistics, and specialized journalism.
Frequently Asked Questions (FAQ)
How much is 1 km/L in MPG (US)?
1 km/L is approximately 2.352145 MPG (US miles per gallon).
How do I convert L/100km to km/L?
Divide 100 by the value in Liters per 100km. ConvertUs performs this inverse calculation automatically for your convenience.
