Conversion Formula
The formula to convert miles per gallon (mpg) to litres per 100 km is: (mpg * 4.54609 / 1.60934) * 100. This works because miles are converted to kilometers (by dividing by 1.60934), gallons are converted to litres (by multiplying by 4.54609), then adjusted to per 100 km.
For example, with 30 mpg: 30 * 4.54609 / 1.60934 = 84.76; then 84.76 / 1 = 84.76, and to get litres per 100 km, multiply by 100, resulting in approximately 7.83 litres.
Conversion Example
- Convert 20 mpg:
- 20 * 4.54609 / 1.60934 = 56.49
- Then, 56.49 / 1 = 56.49, and multiply by 100 gives about 5.65 litres per 100 km.
- Convert 50 mpg:
- 50 * 4.54609 / 1.60934 = 113.22
- Dividing by 1 and multiplying by 100 results in roughly 11.32 litres per 100 km.
- Convert 10 mpg:
- 10 * 4.54609 / 1.60934 = 28.24
- Multiplying by 100 gives about 2.82 litres per 100 km.

Conversion Definitions
mpg
mpg (miles per gallon) measures how many miles a vehicle travels on one gallon of fuel, indicating fuel efficiency in imperial units, used mainly in the UK and some other countries, and helps compare vehicle performance across different regions.
litres
Litres are metric units of volume used to measure fuel quantity, with 1 litre equaling 1000 cubic centimeters; it’s standard in most countries outside the US for expressing fuel capacity and consumption.
Conversion FAQs
Why is converting mpg to litres important for international drivers?
This conversion helps drivers understand fuel efficiency when using different measurement systems, making it easier to compare vehicles or estimate fuel costs across countries that use imperial or metric units.
How accurate is the approximation when converting 30 mpg to litres per 100 km?
The calculation relies on precise constants for miles to kilometers and gallons to litres, so the final value is very close but might vary slightly due to rounding. It provides a practical estimate for everyday use.
Can I use the conversion formula for other fuel efficiency units?
Yes, similar formulas exist for converting between other units, but ensure to use correct constants for each measurement system to get accurate results. The mpg to litres per 100 km formula is specific to imperial to metric conversion.
