Fuel efficiency conversion is essential for international vehicle specifications, fleet management, and comparing fuel economy across different measurement systems. Our tool supports US MPG, UK MPG, L/100km, km/L, and miles per liter.
Understanding Fuel Economy Units
Common Fuel Economy Units:
- MPG (US): Miles per gallon using US gallon (3.785 L). Standard in the United States for vehicle fuel economy ratings.
- MPG (UK): Miles per gallon using Imperial gallon (4.546 L). Used in the United Kingdom and some Commonwealth countries.
- L/100km: Liters per 100 kilometers. Standard metric unit used in Europe, Canada, and most of the world. Lower values = better efficiency.
- km/L: Kilometers per liter. Common in Japan and some Asian countries. Higher values = better efficiency.
- Miles per Liter: Used in some countries for international comparison and hybrid vehicle specifications.
Fuel Economy Conversion Formulas
Essential Fuel Conversions:
- MPG (US) to L/100km: 235.215 ÷ MPG_US = L/100km
- L/100km to MPG (US): 235.215 ÷ L/100km = MPG_US
- MPG (UK) to L/100km: 282.481 ÷ MPG_UK = L/100km
- km/L to MPG (US): km/L × 2.352 = MPG_US
- MPG (US) to km/L: MPG_US ÷ 2.352 = km/L
- km/L to L/100km: 100 ÷ km/L = L/100km
Step-by-Step Conversion Examples:
Convert 30 MPG (US) to L/100km:
235.215 ÷ 30 = 7.84 L/100km
Convert 8 L/100km to MPG (US):
235.215 ÷ 8 = 29.4 MPG (US)
Convert 15 km/L to MPG (US):
15 × 2.352 = 35.3 MPG (US)
