Fuel Economy Conversion Chart
Convert between different fuel economy units including MPG, km/L, L/100km. Easily compare fuel efficiency across different measurement systems.
Step 1: Input Fuel Economy
Understanding Fuel Economy Units
MPG (miles per gallon) measures how many miles a vehicle can travel on one gallon of fuel. L/100km measures how many liters of fuel are needed to travel 100 kilometers. Lower L/100km values indicate better fuel efficiency.

About Fuel Economy Standards
Different countries use different fuel economy measurement systems. The US uses MPG, while most European countries use L/100km. The UK uses MPG but with a different gallon size than the US.

Fuel Economy Conversion Formulas
MPG (US) to L/100km
L/100km = 235.214583 / MPG (US)
MPG (UK) to L/100km
L/100km = 282.480936 / MPG (UK)
km/L to L/100km
L/100km = 100 / km/L
MPG (US) to MPG (UK)
MPG (UK) = MPG (US) × 1.20095
MPG (US) to km/L
km/L = MPG (US) × 0.425144
