Converting 20 mpg to liters per 100 kilometers results in approximately 11.76 liters. This means that a vehicle achieving 20 miles per gallon consumes about 11.76 liters of fuel for every 100 km driven.
To convert mpg to liters per 100 km, we use the formula: Liters/100km = 235.214583 / mpg. This works because 1 mile equals 1.60934 km, and 1 gallon equals 3.78541 liters. By dividing 235.214583 by mpg, we find out how many liters are used per 100 km based on miles per gallon efficiency.

Conversion Formula
The formula to convert miles per gallon (mpg) into liters per 100 kilometers is: Liters/100km = 235.214583 / mpg. This formula arises because 1 mpg equals the amount of liters needed to travel 100 km, based on conversion factors: 1 mile = 1.60934 km, and 1 gallon = 3.78541 liters. Dividing 235.214583 (which combines these conversions) by mpg gives the liters used per 100 km. For example, if a car gets 20 mpg, then: 235.214583 / 20 = 11.76 liters per 100 km, meaning it consumes 11.76 liters to drive 100 km.
Conversion Example
- Convert 30 mpg to liters:
- Apply formula: 235.214583 / 30
- Calculate: 7.84 liters per 100 km
- This indicates that at 30 mpg, the vehicle uses approximately 7.84 liters to travel 100 km.
- Convert 15 mpg to liters:
- Apply formula: 235.214583 / 15
- Calculate: 15.68 liters per 100 km
- This shows that a vehicle with 15 mpg consumes about 15.68 liters per 100 km.
- Convert 25 mpg to liters:
- Apply formula: 235.214583 / 25
- Calculate: 9.41 liters per 100 km
- This means at 25 mpg, the fuel consumption is roughly 9.41 liters per 100 km.

Conversion Definitions
mpg
Miles per gallon (mpg) measures how many miles a vehicle travels on one gallon of fuel, indicating fuel efficiency. Higher mpg means less fuel used per mile, reflecting better efficiency. It’s a common metric in the US to compare vehicle fuel consumption.
liters
Liters are a unit of volume used to quantify fuel quantity in many countries. It measures the amount of liquid held in a container, such as a fuel tank. Converting fuel efficiency to liters helps compare consumption across different measurement systems.
Conversion FAQs
How accurate is the conversion from mpg to liters per 100 km?
The conversion relies on fixed constants and the formula 235.214583 / mpg, providing precise results for standard conditions. Variations in measurement systems or rounding may cause slight differences, but generally, it’s reliable for practical use.
Can I convert liters per 100 km back to mpg using the same formula?
Yes, reversing the process is straightforward: mpg = 235.214583 / liters per 100 km. This formula allows you to switch between units depending on which metric you need, assuming accurate input values.
Why do different countries prefer different units for fuel efficiency?
Country-specific measurement systems influence the units used; the US favors mpg, while Europe and many other nations use liters per 100 km. Historical, cultural, and practical reasons contribute to these preferences, affecting how fuel efficiency is communicated.
