MPG to L/100km Calculator
Convert between MPG (miles per gallon) and L/100km (liters per 100 kilometers) with our comprehensive calculator. Compare fuel efficiency across different measurement systems used worldwide.
Step 1: MPG to L/100km
Understanding MPG Types
US gallons are smaller than UK gallons (3.785 liters vs 4.546 liters), so the same MPG value represents different fuel efficiency. UK MPG values are approximately 20% higher than US MPG for the same fuel consumption.
Step 2: L/100km to MPG
About L/100km
L/100km is the standard fuel economy measurement in most countries. Lower values indicate better fuel efficiency. Most modern efficient cars achieve 5-8 L/100km, while larger vehicles may use 10-15 L/100km or more.

Conversion Formulas
MPG to L/100km Formula
L/100km = 235.214583 / MPG (US)
L/100km = 282.480936 / MPG (UK)
L/100km to MPG Formula
MPG (US) = 235.214583 / L/100km
MPG (UK) = 282.480936 / L/100km
Fuel Cost Calculation
Fuel Cost per 100 miles = (100 / MPG) × Fuel Price per Gallon
