Fuel Consumption Converter

About This Tool

This Fuel Consumption Converter is an automotive tool for converting units of fuel economy and fuel consumption. There are two common ways to express this: distance per unit volume (e.g., miles per gallon), or volume per unit distance (e.g., liters per 100 km). The base unit for this tool is meter per liter (m/L).

This tool is essential for comparing vehicle efficiency between countries that use different standards, and for understanding the relationship between the two different methods of measurement.

Tips & Features

• Economy vs. Consumption: 'Fuel Economy' (distance per volume, like MPG) is a measure of efficiency where a higher number is better. 'Fuel Consumption' (volume per distance, like L/100km) is a measure where a lower number is better. They are inversely related.
• US vs. UK Gallons: A U.S. gallon is smaller than a British (Imperial) gallon. This means a car's MPG rating will be higher (better) if measured with U.S. gallons than with Imperial gallons. This tool includes both.
• The L/100km Standard: Liters per 100 kilometers is the standard measurement in most of the world. It provides a direct measure of how much fuel is needed to travel a set distance.
