Conversion Formula
The formula to convert miles per gallon (mpg) into liters per 100 kilometers (L/100km) is: L/100km = 235.214583 / mpg. This works because there are 1.60934 kilometers in a mile and 3.78541 liters in a gallon. Multiplying these conversions gives the factor 235.214583.
For example, for 20 mpg: 235.214583 / 20 = 11.76 liters per 100 km. This shows that at 20 mpg, the vehicle consumes about 11.76 liters of fuel every 100 km.
Conversion Example
- Convert 30 mpg:
- Apply formula: 235.214583 / 30
- Result: 7.84 liters per 100 km
- This indicates a more fuel-efficient vehicle.
- Convert 15 mpg:
- Apply formula: 235.214583 / 15
- Result: 15.68 liters per 100 km
- This means the vehicle uses more fuel per distance traveled.
- Convert 25 mpg:
- Apply formula: 235.214583 / 25
- Result: 9.41 liters per 100 km
- This shows moderate fuel efficiency.

Conversion Definitions
mpg
Miles per gallon (mpg) measures how many miles a vehicle can travel using one gallon of fuel, indicating fuel efficiency in the imperial system; higher mpg means better fuel economy.
liters
Liters are a metric unit of volume used to quantify fuel capacity or consumption; it represents how much space fuel occupies, with more liters indicating higher fuel use over a distance.
Conversion FAQs
How accurate is the conversion from mpg to liters per 100 km?
The conversion is precise when using the exact formula 235.214583 / mpg, but slight variations can occur due to rounding or measurement inaccuracies in original mpg figures.
Can I use this conversion for all vehicles regardless of fuel type?
Yes, the conversion applies to any vehicle’s fuel efficiency measurement in mpg, regardless of fuel type, since it depends solely on volume and distance units.
Why does the conversion formula use 235.214583?
This number combines the conversion factors of miles to kilometers and gallons to liters, specifically 1 mile = 1.60934 km and 1 gallon = 3.78541 liters, multiplied together for direct conversion.
Is there a way to convert liters back to mpg?
Yes, simply reverse the formula: mpg = 235.214583 / liters per 100 km, allowing you to convert from liters per 100 km back to mpg.
How does changing the mpg value affect liters per 100 km?
As mpg increases, liters per 100 km decrease, indicating better fuel efficiency; the relationship is inverse, so doubling mpg roughly halves the liters per 100 km.
