The conversion of 15 mpg to liter per 100 km results in approximately 15.68 liters. This indicates that a vehicle getting 15 miles per gallon consumes about 15.68 liters of fuel to travel 100 kilometers. The calculation helps compare fuel efficiency across different measurement systems.
To convert mpg to liters per 100 km, the formula involves multiplying the miles per gallon value by 4.54609 (liters per gallon) and dividing by 1.60934 (miles per kilometer), then multiplying by 100 to get per 100 km. The simplified version is: (235.21 / mpg). For 15 mpg, it’s 235.21 / 15 ≈ 15.68 liters per 100 km.

Conversion Formula
The formula to change mpg to liters per 100 km takes the number of miles per gallon and converts it into fuel consumption per 100 km. It works because 1 gallon equals 4.54609 liters, and 1 mile equals 1.60934 km. By dividing 235.21 (which is 100 km divided by miles per gallon), it gets the liters needed for 100 km.
Example: For 20 mpg, calculation is 235.21 / 20 = 11.76 liters per 100 km, meaning the vehicle uses that much fuel to go 100 km.
Conversion Example
– Convert 25 mpg to liters per 100 km:
– Step 1: Use formula 235.21 / mpg.
– Step 2: 235.21 / 25 = 9.41 liters.
– Step 3: The vehicle consumes about 9.41 liters per 100 km.
– Convert 10 mpg:
– 235.21 / 10 = 23.52 liters.
– Convert 30 mpg:
– 235.21 / 30 = 7.84 liters.
– Convert 50 mpg:
– 235.21 / 50 = 4.70 liters.
– Convert 5 mpg:
– 235.21 / 5 = 47.04 liters.

Conversion Definitions
mpg: Miles per gallon measures how many miles a vehicle can travel on one gallon of fuel, indicating fuel efficiency. Higher mpg means the vehicle consumes less fuel for longer distances, and it is used mainly in the US and UK measurement systems.
liter: A liter is a metric unit of volume equal to 1 cubic decimeter, used to measure liquids including fuel. It is part of the metric system, and commonly used worldwide for fuel quantities, with 1 liter roughly equivalent to 0.264 gallons.
Conversion FAQs
Why does my mpg number decrease when I convert to liters per 100 km?
Because mpg and liters per 100 km are inversely related; a higher mpg indicates better fuel efficiency, which translates to lower liters per 100 km. When converting, the larger the mpg, the smaller the liters per 100 km number, reflecting more efficiency.
Is the conversion of mpg to liters per 100 km the same for all vehicles?
No, the conversion is a mathematical calculation based on fixed constants for volume and distance units. It applies universally, but actual fuel consumption depends on vehicle specifics, driving conditions, and maintenance, which impact real-world efficiency.
Can I use this conversion to compare fuel efficiencies between US and European cars?
Yes, because mpg is primarily used in the US, while liters per 100 km is common in Europe. Converting between them allows direct comparison of fuel efficiency, but remember that driving styles and testing methods can cause variations.
What are the limitations of converting mpg to liters per 100 km?
The conversion provides an approximate value based on fixed constants; real fuel consumption can vary due to factors like driving habits, terrain, vehicle condition, and measurement standards, which this simple calculation doesn’t account for.
