Converting 32 miles per gallon (mpg) results in approximately 8.78 litres per 100 km.
This conversion means that a vehicle which covers 32 miles per gallon consumes about 8.78 litres of fuel for every 100 kilometers traveled. The calculation takes into account that 1 mile equals 1.60934 kilometers and 1 gallon equals 4.54609 litres, translating fuel efficiency from mpg to litres per 100 km.
Understanding the Conversion from mpg to litres
To change mpg to litres per 100 km, you need to convert miles to kilometers and gallons to litres. The formula involves dividing 100 by the miles per gallon, then multiplying by the litre equivalent of a gallon, adjusting for the kilometer conversion. This gives an accurate measure of fuel consumption in litres per 100 km.

Conversion Formula
The formula to convert mpg to litres per 100 km is: litres per 100 km = (100 / mpg) * 4.54609 / 1.60934. It works by first calculating how many liters are consumed per mile, then scaling it to 100 km, considering that 1 mile equals 1.60934 km, and 1 gallon equals 4.54609 liters. For example, 32 mpg: 100 / 32 = 3.125; 3.125 * 4.54609 ≈ 14.208; 14.208 / 1.60934 ≈ 8.83 litres per 100 km.
Conversion Example
- Convert 25 mpg:
- Calculate 100 / 25 = 4
- Multiply 4 * 4.54609 ≈ 18.18436
- Divide 18.18436 / 1.60934 ≈ 11.30 litres per 100 km
- Convert 50 mpg:
- Calculate 100 / 50 = 2
- Multiply 2 * 4.54609 ≈ 9.09218
- Divide 9.09218 / 1.60934 ≈ 5.65 litres per 100 km
- Convert 15 mpg:
- Calculate 100 / 15 ≈ 6.6667
- Multiply 6.6667 * 4.54609 ≈ 30.310
- Divide 30.310 / 1.60934 ≈ 18.83 litres per 100 km

Conversion Definitions
mpg (miles per gallon): A measurement of fuel efficiency showing how many miles a vehicle can travel using one gallon of fuel. It is used mainly in the United States and UK to compare vehicle fuel economy.
litres: A metric unit of volume used to measure liquids, including fuel. One litre equals 1,000 cubic centimeters and is standard in most countries for fuel measurement.
Conversion FAQs
How does changing the mpg value affect the litres per 100 km calculation?
Lower mpg numbers indicate higher fuel consumption, resulting in higher litres per 100 km. Conversely, higher mpg values mean less fuel used per distance, leading to lower litres per 100 km. The conversion formula directly reflects this inverse relationship.
Can I use the conversion formula for any mpg value?
Yes, the formula applies universally for any mpg value. It accurately converts miles per gallon to litres per 100 km regardless of the number, as it accounts for the metric and imperial unit differences.
What are the typical fuel consumption ranges for vehicles in litres per 100 km?
Most vehicles fall between about 4 to 15 litres per 100 km, with higher values indicating less fuel efficiency. Sports cars and older models tend to be higher, while modern economy cars often have lower fuel consumption figures.
Why is converting mpg to litres per 100 km useful?
This conversion helps compare vehicles across countries that use different measurement systems and provides a clearer understanding of fuel efficiency in terms of fuel volume used over a standard distance.
