15 mpg equals approximately 6.3776 kmpl.
This conversion is done by multiplying the miles per gallon (mpg) value by the factor 0.425144, which converts miles into kilometers and gallons into liters. The result shows how many kilometers a vehicle can travel per liter of fuel when it has a fuel efficiency of 15 mpg.

Conversion Formula
The formula to convert miles per gallon (mpg) to kilometers per liter (kmpl) is:
kmpl = mpg × 1.609344 ÷ 3.785411784
This works because 1 mile equals 1.609344 kilometers and 1 gallon equals 3.785411784 liters. By converting the miles to kilometers and gallons to liters, you get the distance traveled in kilometers per liter of fuel.
Example calculation for 15 mpg:
- Multiply 15 by 1.609344 = 24.14016 kilometers per gallon
- Divide 24.14016 by 3.785411784 = 6.3776 kilometers per liter
Conversion Example
- 20 mpg to kmpl:
- Multiply 20 × 1.609344 = 32.18688 km per gallon
- Divide 32.18688 ÷ 3.785411784 = 8.3775 km per liter
- So 20 mpg equals about 8.3775 kmpl.
- 25 mpg to kmpl:
- 25 × 1.609344 = 40.2336 kilometers per gallon
- 40.2336 ÷ 3.785411784 = 10.4719 kilometers per liter
- Therefore, 25 mpg is approximately 10.4719 kmpl.
- 10 mpg to kmpl:
- 10 × 1.609344 = 16.09344 km per gallon
- 16.09344 ÷ 3.785411784 = 4.2514 km per liter
- So, 10 mpg equals about 4.2514 kmpl.
- 5 mpg to kmpl:
- 5 × 1.609344 = 8.04672 km per gallon
- 8.04672 ÷ 3.785411784 = 2.1257 km per liter
- Thus, 5 mpg converts to approximately 2.1257 kmpl.

Conversion Definitions
mpg: Miles per gallon (mpg) measures how far a vehicle travels using one gallon of fuel. It is common in countries using imperial units, expressing fuel efficiency by the distance in miles covered per gallon consumed. Useful for comparing vehicle fuel consumption.
kmpl: Kilometers per liter (kmpl) measures fuel efficiency by showing how many kilometers a vehicle travels on one liter of fuel. It is common in metric system countries and helps drivers understand fuel usage relative to distance traveled in kilometers.
Conversion FAQs
Why does converting mpg to kmpl involve both miles and gallons?
The conversion needs to adjust both distance and volume units. Since mpg uses miles and gallons, converting to kmpl requires changing miles into kilometers and gallons into liters, which explains the two-part calculation in the formula.
Can I simply multiply mpg by 1.6 to get kmpl?
No, multiplying mpg by 1.6 only converts miles to kilometers but ignores converting gallons into liters. The gallon-to-liter factor reduces the final value, so both conversions must be accounted for to get accurate kmpl.
Why do some conversions show slightly different kmpl values for the same mpg?
Rounding differences or using approximate conversion constants can cause minor variations. Using precise constants like 1.609344 for miles to kilometers and 3.785411784 for gallons to liters leads to consistent results.
Is negative mpg possible when converting to kmpl?
Negative mpg values are not physically meaningful for fuel efficiency, but mathematically, the formula can process them. Negative fuel efficiency would imply impossible scenarios like traveling backward or gaining fuel, so they are ignored in practical contexts.
Does this conversion apply to both US and UK gallons?
The formula uses US gallons, which equals 3.785411784 liters. UK gallons are larger (4.54609 liters), so converting mpg to kmpl using UK gallons requires a different factor. Make sure to clarify the gallon type when converting.
