fuel Converter

Convert fuel economy units instantly with our free online fuel converter. Whether you need to convert MPG to L/100km, km/L to MPG, or any other fuel efficiency conversion, our calculator provides accurate results for automotive, fleet management, and travel planning.

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.

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.

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)

Common Uses for Fuel Economy Conversion:

• Vehicle Shopping: Comparing fuel efficiency between US and European vehicle specifications when buying cars internationally.
• Fleet Management: Standardizing fuel consumption reports across different regions and vehicle types for business operations.
• Travel Planning: Calculating fuel costs and consumption for international road trips and vacation planning.
• Environmental Impact: Converting vehicle efficiency ratings to calculate carbon footprint and emissions for sustainability reporting.
• Automotive Industry: Converting manufacturer specifications between different market regions (US, EU, Asia).
• Cost Analysis: Comparing operating costs of vehicles with different fuel economy ratings and local fuel prices.
• Government Reporting: Converting fleet efficiency data for regulatory compliance and emissions reporting.
