Converting 9 mpg to liters results in approximately 26.27 liters per 100 kilometers.
This conversion transforms miles per gallon into liters per 100 kilometers by using the standard conversion factors: 1 mile equals 1.60934 kilometers, and 1 gallon equals 3.78541 liters. So, 9 mpg equals (100 km / (mpg * 1.60934 km/mile)) * 3.78541 liters per gallon, which simplifies to roughly 26.27 liters per 100 km.
Understanding the Conversion Process
To convert miles per gallon to liters per 100 kilometers, you first change miles to kilometers and gallons to liters, then adjust for the standard metric measure of fuel consumption per 100 km. This method ensures accurate measurement across different unit systems, making it easier to compare fuel efficiencies.

Conversion Formula
The formula to convert mpg to liters per 100 km is: (235.21 / mpg). This works because converting miles to kilometers (1 mile = 1.60934 km) and gallons to liters (1 gallon = 3.78541 liters) results in a constant factor of 235.21. Dividing 235.21 by mpg gives the fuel consumption in liters per 100 km.
For example, if a vehicle gets 10 mpg: 235.21 / 10 = 23.521 liters per 100 km. This calculation shows how much fuel in liters it would consume to travel 100 km at that mpg rate.
Conversion Example
- Convert 15 mpg to liters per 100 km:
- Apply the formula: 235.21 / 15 = 15.68 liters per 100 km.
- This means the vehicle uses 15.68 liters to travel 100 km.
- Convert 20 mpg to liters per 100 km:
- Apply the formula: 235.21 / 20 = 11.76 liters per 100 km.
- This indicates a more efficient fuel consumption compared to 15 mpg.
- Convert 25 mpg to liters per 100 km:
- Apply the formula: 235.21 / 25 = 9.41 liters per 100 km.
- This shows a higher fuel efficiency than 20 mpg.
- Convert 5 mpg to liters per 100 km:
- Apply the formula: 235.21 / 5 = 47.04 liters per 100 km.
- This indicates very poor fuel economy, using a lot of fuel per 100 km.
- Convert 30 mpg to liters per 100 km:
- Apply the formula: 235.21 / 30 = 7.84 liters per 100 km.
- This represents excellent fuel efficiency.

Conversion Definitions
mpg: Miles per gallon measures how many miles a vehicle can travel on one gallon of fuel, reflecting fuel efficiency in imperial units. Higher mpg indicates better fuel economy, and it is mostly used in the United States and the UK.
liters: Liters are metric units of volume used to quantify liquid substances, including fuel. One liter equals 1,000 cubic centimeters, and it is the standard unit for measuring fuel quantities outside the imperial system.
Conversion FAQs
How accurate is the conversion from mpg to liters per 100 km?
The conversion is precise, relying on exact conversion factors for miles to kilometers and gallons to liters. Small rounding differences may occur, but overall, the formula provides reliable results for practical purposes.
Can I use the same conversion factor for all vehicles?
Yes, the conversion factor applies universally because it is based on fixed unit conversions. However, actual fuel efficiency varies based on vehicle type, driving conditions, and maintenance, not the conversion factor itself.
Why does fuel efficiency look different in liters per 100 km compared to mpg?
Because mpg measures miles per gallon, a higher number means better economy, whereas liters per 100 km shows fuel used per distance traveled, so a lower number indicates better efficiency. They are inverse measures, which can be confusing without conversion.
Is converting negative mpg values meaningful?
Negative mpg values are not meaningful in real-world scenarios; they may appear due to data errors or unconventional measurements. Typically, mpg values are positive, indicating positive fuel economy.
How do I interpret a very low liters per 100 km number?
A low liters per 100 km number indicates high fuel efficiency, meaning the vehicle consumes less fuel to cover 100 km. Conversely, high numbers suggest poor efficiency and higher fuel consumption.
