15 miles per gallon (mpg) is approximately 5.68 liters per 100 kilometers.
Converting 15 mpg to liters involves understanding how miles per gallon translates to liters per 100 km, which is a common metric measurement. Since 1 mpg equals about 0.4251 liters per 100 km, multiplying 15 by this factor gives the approximate value.
Understanding the Conversion
The conversion from mpg to liters per 100 km is based on the relationship between miles and kilometers, and gallons and liters. The formula multiplies the mpg value by 0.4251 to find liters per 100 km. For example, 15 mpg times 0.4251 equals roughly 5.68 liters per 100 km.

Conversion Formula
The formula for converting mpg (miles per gallon) to liters per 100 km is: liters/100km = mpg * 0.4251. This works because 1 mile equals 1.60934 km, and 1 gallon equals 3.78541 liters. So, dividing 100 km by miles per gallon and converting units gives the factor 0.4251.
For example, if you have 10 mpg: 10 * 0.4251 = 4.251 liters per 100 km. This step-by-step calculation shows how the conversion factor accounts for unit differences.
Conversion Example
- Convert 20 mpg:
- Multiply 20 by 0.4251
- 20 * 0.4251 = 8.502 liters per 100 km
- Convert 25 mpg:
- Multiply 25 by 0.4251
- 25 * 0.4251 = 10.6275 liters per 100 km
- Convert 30 mpg:
- Multiply 30 by 0.4251
- 30 * 0.4251 = 12.753 liters per 100 km
- Convert 12 mpg:
- Multiply 12 by 0.4251
- 12 * 0.4251 = 5.1012 liters per 100 km

Conversion Definitions
mpg
MpG means miles per gallon, indicating how many miles a vehicle can travel using one gallon of fuel, reflecting fuel efficiency in imperial units. Higher mpg values mean better fuel consumption, and it’s used mainly in the United States and the UK.
liters
Liters is a metric unit of volume used to measure liquids, including fuel. It indicates the amount of fuel a vehicle consumes or holds. Converting fuel efficiency to liters helps compare vehicles across regions that use the metric system more commonly.
Conversion FAQs
How accurate is the conversion from mpg to liters per 100 km?
The conversion relies on a fixed factor (0.4251), which is accurate for standard unit conversions between miles, kilometers, gallons, and liters. Variations in measurement precision or rounding can slightly affect the exactness, but generally, results are reliable.
What does a lower liters per 100 km number mean about a vehicle’s efficiency?
A lower liters per 100 km value indicates that the vehicle consumes less fuel to travel 100 km, meaning it is more fuel-efficient. Conversely, higher numbers suggest higher fuel consumption and less efficiency.
Can I convert liters per 100 km back to mpg?
Yes, by reversing the formula: mpg = 100 / (liters per 100 km * 0.4251). This allows you to estimate miles per gallon based on fuel consumption in liters per 100 km, useful for comparing with mpg ratings.
