How do you convert L/100km to MPG US?

Since L/100km is consumption (volume over distance) and MPG is economy (distance over volume), they are reciprocals. To convert L/100km to MPG US, divide 235.215 by the L/100km value. For example, 10 L/100km is equivalent to 23.52 MPG US.

What is the difference between US MPG and UK MPG?

The Imperial (UK) gallon is larger than the US gallon. One UK gallon is exactly 4.54609 liters, while one US gallon is exactly 3.78541 liters. Consequently, 1 UK MPG is equivalent to approximately 0.8327 US MPG.

How do you convert km/L to MPG US?

To convert kilometers per liter (km/L) to miles per gallon (MPG US), multiply the km/L value by approximately 2.35215.

Understanding Fuel Consumption vs. Fuel Economy

When buying or evaluating vehicles, understanding fuel performance metrics is key. E.g. check the official U.S. EPA Fuel Economy website. Broadly, performance falls into two categories:

Fuel Economy: Measures the distance a vehicle travels per unit of fuel (e.g. Miles per Gallon or Kilometers per Liter). Higher ratings mean better performance.
Fuel Consumption: Measures the volume of fuel consumed over a standard distance (e.g. Liters per 100 Kilometers). Lower ratings mean better efficiency.

Because these metrics are mathematical reciprocals, translating them manually requires step-by-step divisions. Our **fuel consumption converter** does this instantly in your browser.

Global Standard Fuel Units Explained

Different countries employ different specifications for vehicle marketing and efficiency metrics:

L/100km: Standard metric consumption used in Europe, Canada, Australia, and China.
MPG (US): Standard in the United States. Based on the US liquid gallon (~3.785 L).
MPG (UK): Standard in the United Kingdom. Based on the Imperial gallon (~4.546 L).
km/L: Commonly used in Japan, Latin America, and parts of Asia.
