MPG to L/100km Conversion Formula:
| From: | To: |
The MPG to L/100km conversion is used to translate fuel efficiency measurements between the US system (miles per gallon) and the metric system (liters per 100 kilometers). This conversion is particularly useful for comparing vehicle fuel efficiency across different measurement systems.
The calculator uses the conversion formula:
Where:
Explanation: The constant 235.215 is derived from the conversion factors between miles and kilometers, and between US gallons and liters.
Details: Understanding fuel efficiency in both measurement systems is crucial for international vehicle comparisons, fuel consumption calculations for travel planning, and environmental impact assessments across different regions.
Tips: Enter the MPG value (miles per gallon) in the input field. The value must be greater than 0. The calculator will automatically compute the equivalent fuel consumption in liters per 100 kilometers.
Q1: Why is the conversion factor 235.215?
A: This number comes from the conversion of 1 mile = 1.609344 km and 1 US gallon = 3.785411784 liters. The calculation is: (100 km × 3.785411784 L/gal) ÷ 1.609344 km/mile = 235.2145833.
Q2: Does this conversion work for both US and UK gallons?
A: No, this conversion is specifically for US gallons. UK gallons are larger (1 UK gallon = 4.54609 liters), so a different conversion factor would be needed for UK MPG.
Q3: What is considered good fuel efficiency in L/100km?
A: Generally, below 6 L/100km is excellent, 6-8 L/100km is good, 8-10 L/100km is average, and above 10 L/100km is poor fuel efficiency for passenger vehicles.
Q4: How does MPG relate to environmental impact?
A: Higher MPG values (or lower L/100km values) indicate better fuel efficiency, which typically means lower CO2 emissions and reduced environmental impact per distance traveled.
Q5: Can I convert L/100km back to MPG?
A: Yes, the reverse conversion is: MPG = 235.215 ÷ L/100km.
