Fuel Economy Converters - Convert MPG, L/100km, km/L & More

What is Fuel Economy Conversion?

Fuel economy conversion is the process of converting fuel efficiency measurements between different units of measurement. Fuel economy represents the distance a vehicle can travel per unit of fuel consumed, measured in units such as miles per gallon (MPG), liters per 100 kilometers (L/100km), and kilometers per liter (km/L). Our fuel economy converters handle the complex relationships between various efficiency units used across different countries, automotive markets, and transportation systems.

Fuel economy measurements are crucial in numerous fields including automotive engineering, transportation planning, environmental analysis, consumer vehicle selection, and fuel cost analysis. Accurate fuel economy conversion ensures proper vehicle comparison, fuel planning, and environmental impact assessment across diverse applications from personal transportation to commercial fleet management.

Types of Fuel Economy Units We Support

Imperial Fuel Economy Units

Imperial fuel economy units are commonly used in the United States and some other countries and include miles per gallon (MPG) and gallons per mile (GPM). These units provide intuitive understanding for users familiar with the imperial measurement system, where higher MPG values indicate better fuel efficiency. MPG is widely used in automotive marketing, fuel economy ratings, and consumer vehicle comparisons.

Metric Fuel Economy Units

Metric fuel economy units are the international standard and include liters per 100 kilometers (L/100km) and kilometers per liter (km/L). These units are used in most countries worldwide and provide a different perspective on fuel efficiency, where lower L/100km values indicate better fuel economy. Metric units are essential for international vehicle comparisons and environmental analysis.

Hybrid Fuel Economy Units

Hybrid fuel economy units include combinations of imperial and metric measurements such as miles per liter (MPL) and gallons per 100 miles (GPM). These units are used in specific applications and regions where mixed measurement systems are preferred. Converting between these units enables comprehensive fuel economy analysis across different measurement preferences.
