Miles per gallon (MPG) is the standard measure of fuel economy in the United States. It represents the number of miles a vehicle can travel on one gallon of fuel. Higher MPG values indicate better fuel efficiency. The US gallon contains 3.785 liters.
Kilometers per liter is a metric measure of fuel economy used in many countries worldwide. It represents how many kilometers a vehicle can travel on one liter of fuel. Like MPG, higher km/L values indicate better fuel efficiency.
It's important to note that US MPG and UK MPG are different measurements. The UK (Imperial) gallon is larger at 4.546 liters, compared to the US gallon at 3.785 liters. This means a vehicle rated at 30 MPG (US) would be approximately 36 MPG (UK). When converting to km/L, always specify whether you're using US or UK gallons.
Converting between MPG and km/L is essential for international travelers, automotive journalists, and anyone comparing vehicle specifications across different markets. Understanding these conversions helps when purchasing imported vehicles or planning fuel costs for international road trips.
To convert US miles per gallon to kilometers per liter, multiply the MPG value by 0.425144. For example, 25 MPG × 0.425144 = 10.63 km/L. This conversion accounts for the difference between miles and kilometers, as well as gallons and liters.
Yes, 10 km/L (approximately 23.5 MPG) is considered reasonable fuel economy for many vehicles. Compact cars and hybrids often achieve 12-20 km/L, while larger vehicles like SUVs and trucks typically get 6-10 km/L. Modern efficient vehicles can exceed 20 km/L.
Both MPG and km/L measure distance traveled per unit of fuel, so higher numbers indicate greater efficiency. This is different from L/100km (used in Europe), where lower numbers indicate better efficiency because it measures fuel consumed per distance traveled.
The US gallon is 3.785 liters, while the UK (Imperial) gallon is 4.546 liters - about 20% larger. This means UK MPG figures are approximately 20% higher than US MPG for the same vehicle. Always verify which gallon measurement is being used when comparing fuel economy figures.
