20 mpg equals approximately 9.41 liters per 100 kilometers.
This conversion shows how many liters are used to travel 100 kilometers if a vehicle gets 20 miles per gallon. Since mpg measures miles per gallon and liters measure fuel volume, we need to convert miles to kilometers and gallons to liters to achieve this result.
Conversion Result
If you convert 20 mpg into liters per 100 km, it approximately equals 9.41 liters. This means a vehicle consuming 20 miles per gallon uses about 9.41 liters of fuel to travel 100 kilometers.

Conversion Formula
The formula used to convert miles per gallon to liters per 100 kilometers is: liters/100km = 235.214583 / mpg. This works because 1 mile equals 1.60934 kilometers, and 1 gallon equals 3.78541 liters. Dividing 235.214583 by mpg gives liters per 100 km.
- Start with mpg (miles per gallon).
- Divide 235.214583 by mpg (e.g., 20).
- The result is liters per 100 km.
Conversion Example
- Convert 30 mpg:
- 235.214583 ÷ 30 = 7.84 liters per 100 km.
- This means at 30 mpg, a vehicle uses about 7.84 liters to go 100 km.
- Convert 15 mpg:
- 235.214583 ÷ 15 = 15.68 liters per 100 km.
- At 15 mpg, the fuel consumption increases to 15.68 liters per 100 km.
- Convert 50 mpg:
- 235.214583 ÷ 50 = 4.70 liters per 100 km.
- With 50 mpg, the vehicle uses roughly 4.70 liters per 100 km.

Conversion Definitions
mpg
MpG, or miles per gallon, measures how many miles a vehicle can travel using one gallon of fuel, indicating fuel efficiency in imperial units. Higher mpg means less fuel used per mile, reflecting better fuel economy.
liters
Liters is a metric volume unit used to quantify fuel quantity in a tank or consumption over distance, with one liter equaling 1,000 cubic centimeters. It is standard in many countries for measuring fuel and liquid volumes.
Conversion FAQs
How accurate is the conversion from mpg to liters per 100 km?
The conversion formula is precise because it relies on fixed constants for miles to kilometers and gallons to liters, making the calculations reliable for practical fuel economy conversions, although slight variations may occur due to rounding.
Can I use the same formula for converting any mpg value?
Yes, the formula 235.214583 divided by mpg is applicable for all mpg values to find liters per 100 km, regardless of whether the mpg is high or low, providing a consistent method for conversions.
Why does the result become very high when mpg is negative or zero?
Negative or zero mpg values are physically meaningless because they suggest negative or no fuel efficiency, leading to invalid or infinitely high liters per 100 km readings. Always use positive mpg values for valid conversions.
What is the significance of the number 235.214583 in the formula?
This number combines conversion factors for miles to kilometers and gallons to liters, specifically 100 km divided by miles per gallon, making it the key constant for converting mpg to liters per 100 km accurately.
