15 miles per gallon is approximately 9.40 liters per 100 kilometers.
This conversion helps to understand fuel efficiency by translating miles per gallon (mpg) into liters per 100 km, a more common measure outside the US. To get this, we convert miles to kilometers and gallons to liters, then adjust the ratio accordingly.
Conversion Result and Explanation
Converting 15 mpg to liters involves changing miles per gallon into liters per 100 kilometers, which is a standard measure in many countries. The result of about 9.40 liters per 100 km means that for every 100 km traveled, approximately 9.40 liters of fuel would be used.

Conversion Formula
To convert mpg into liters per 100 km, the formula is: liters per 100 km = 235.214583 / mpg. This works because 1 mile equals approximately 1.60934 kilometers and 1 gallon equals about 3.78541 liters. By dividing 235.214583 by mpg, we get the liters used per 100 km.
For example, with 15 mpg: 235.214583 / 15 = 15.68 liters per 100 km, meaning at 15 mpg, a vehicle consumes about 15.68 liters to travel 100 km.
Conversion Example
- Convert 20 mpg:
- Apply formula: 235.214583 / 20 = 11.76 liters/100 km.
- This means at 20 mpg, the vehicle uses about 11.76 liters per 100 kilometers.
- Convert 10 mpg:
- Apply formula: 235.214583 / 10 = 23.52 liters/100 km.
- Thus, 10 mpg equals roughly 23.52 liters per 100 km.
- Convert 25 mpg:
- Apply formula: 235.214583 / 25 = 9.41 liters/100 km.
- So, at 25 mpg, about 9.41 liters are used for 100 km.
- Convert 5 mpg:
- Apply formula: 235.214583 / 5 = 47.04 liters/100 km.
- This indicates very poor fuel efficiency, with 47.04 liters per 100 km.

Conversion Definitions
mpg
MPG stands for miles per gallon, measuring how many miles a vehicle can travel using one gallon of fuel. It is a common way to express fuel efficiency in the US, with higher MPG indicating better fuel economy and lower fuel costs.
liters
Liters are metric units of volume used to measure liquids, including fuel. One liter equals 1,000 cubic centimeters, and it provides a standardized way to quantify fuel consumption across different countries and measurement systems.
Conversion FAQs
How accurate is the conversion from mpg to liters per 100 km?
The conversion formula provides a close approximation based on standard conversion factors, but small variations may occur due to rounding or differences in measurement standards. For most purposes, the result is sufficiently precise.
Why do different countries prefer liters per 100 km instead of mpg?
Many countries outside the US prefer liters per 100 km because it aligns with their metric system and provides a straightforward way to compare fuel consumption regardless of distance traveled, with lower values indicating better efficiency.
Can I convert liters per 100 km back to mpg?
Yes, by reversing the formula: mpg = 235.214583 / liters per 100 km. This allows you to convert from metric fuel efficiency measurements back to miles per gallon for comparisons or preferences.
What factors can affect the accuracy of these conversions?
Variations in fuel density, measurement standards, and rounding can influence conversions. Additionally, actual fuel efficiency may differ based on driving conditions, vehicle maintenance, and load, which the formulas do not account for.
Is there a quick way to estimate liters per 100 km from mpg without a calculator?
For rough estimates, dividing 235 by the mpg value gives a close approximation. For example, at 15 mpg: 235 / 15 ≈ 15.7 liters per 100 km. This quick method helps when precise calculations are not necessary.
