How to Calculate Fuel Consumption Converter
What is Fuel Consumption Converter?
Fuel consumption converters translate between MPG, L/100km, km/L, miles/gallon (imperial and US), and mass-based efficiency.
Formula
US: 235.2 / L/100km = MPG
- US
- MPG — MPG
- L
- MPG (imperial) — MPG (imperial)
- MPG
- MPG value — Variable used in the calculation
Step-by-Step Guide
- 1US: 235.2 / L/100km = MPG
- 2UK: 282.5 / L/100km = MPG (imperial)
- 3Higher MPG is better efficiency; lower L/100km is better efficiency
Worked Examples
Input
30 MPG (US) car
Result
7.84 L/100km, 12.7 km/L
Typical mid-size vehicle
Common Mistakes to Avoid
- ✕Comparing MPG across US/imperial/metric without conversion
- ✕Assuming EPA ratings match personal driving patterns
Frequently Asked Questions
Why do US and imperial MPG differ?
Different gallon sizes: US gallon 3.785 L vs. imperial 4.546 L. Metric L/100km is more intuitive.
How accurate are EPA estimates?
EPA testing procedures updated; real-world often 10-20% worse due to aggressive driving and not-ideal conditions.
