Conversion Formula
The formula to convert mpg to litres per 100 km involves changing miles to kilometres and gallons to litres. Multiply mpg by 1.60934 to convert miles to km, then divide 100 km by this value. Finally, multiply by 3.78541 to convert gallons to litres. This gives litres per 100 km.
For example, for 22 mpg:
- Convert miles to km: 22 * 1.60934 = 35.40448 km
- Calculate km per gallon: 35.40448 km
- Calculate litres per 100 km: (100 / 35.40448) * 3.78541 ≈ 10.72 litres
Conversion Example
Let’s convert 30 mpg step-by-step:
- Multiply 30 mpg by 1.60934 to get km per gallon: 30 * 1.60934 = 48.2802 km
- Divide 100 km by 48.2802 km: 100 / 48.2802 ≈ 2.071 litres per gallon
- Multiply by 3.78541 to convert gallons to litres: 2.071 * 3.78541 ≈ 7.84 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, used mainly in the US and UK to compare vehicle fuel economy.
litres: A metric unit of volume used to measure liquids like fuel; one litre equals 1,000 cubic centimeters or about 0.264 gallons in US measurement.
Conversion FAQs
Why is converting mpg to litres important?
Converting mpg to litres allows comparison of fuel efficiency across countries with different measurement systems, helping users understand fuel consumption in familiar units and make better decisions about vehicles or fuel costs.
Is the conversion exact or approximate?
The conversion provides an estimate based on fixed constants for miles to km and gallons to litres. Small variations may occur due to rounding, but overall, it’s a close approximation for practical purposes.
Can I use this conversion for electric vehicles?
No, since electric vehicles don’t use fuel measured in gallons or litres, this conversion is only suitable for traditional internal combustion engine vehicles.
What is the significance of 100 km in the formula?
100 km serves as a standard distance to measure fuel consumption, making it easy to compare efficiency across vehicles regardless of their total distance traveled, converting the units into a comparable metric.
How do I convert other mpg values to litres per 100 km?
