The conversion of 30 mpg to litres per 100 km results in approximately 7.84 litres. This means that if a vehicle gets 30 miles per gallon, it consumes about 7.84 litres of fuel for every 100 km traveled.
To convert miles per gallon (mpg) to litres per 100 km, you need to understand the relationship between miles, gallons, and litres. Since 1 mile equals 1.60934 km, and 1 gallon equals 3.78541 litres, the conversion involves these factors. The formula takes the inverse of mpg, adjusts for these unit conversions, and gives litres per 100 km, which is a standard metric fuel consumption measure.

Conversion Formula
The formula to convert mpg into litres per 100 km is: (235.214583 / mpg). It works because 1 mile equals 1.60934 km, and 1 gallon equals 3.78541 litres. Dividing 235.214583 (which is 100 * 3.78541 / 1.60934) by mpg gives the litres used per 100 km.
Example: For 30 mpg, calculation is 235.214583 divided by 30, which equals approximately 7.84 litres per 100 km, showing fuel consumption for a vehicle with that mpg rate.
Conversion Example
- Convert 20 mpg:
- Apply formula: 235.214583 / 20 = 11.76 litres per 100 km.
- This shows that a vehicle with 20 mpg consumes about 11.76 litres over 100 km.
- Convert 50 mpg:
- Applying formula: 235.214583 / 50 = 4.70 litres per 100 km.
- This indicates a more fuel-efficient vehicle uses 4.70 litres for 100 km.
- Convert 15 mpg:
- Calculation: 235.214583 / 15 ≈ 15.68 litres per 100 km.
- This shows a less efficient vehicle consumes 15.68 litres per 100 km.
- Convert 45 mpg:
- Calculation: 235.214583 / 45 ≈ 5.22 litres per 100 km.
- This indicates a vehicle uses about 5.22 litres for every 100 km.

Conversion Definitions
mpg
MPG (miles per gallon) measures how many miles a vehicle can travel on one gallon of fuel, indicating fuel efficiency in imperial units. Higher mpg means less fuel used per mile, reflecting better fuel economy in miles and gallons.
litres
Litres are metric units of volume used to quantify fuel volume, with 1 litre equaling 1.057 quarts. In fuel consumption, litres measure how much fuel a vehicle consumes over a distance, often expressed per 100 km for international standards.
Conversion FAQs
How accurate is the conversion from mpg to litres per 100 km?
The conversion is highly accurate when using the standard formula: 235.214583 divided by mpg, which accounts for precise unit conversions between miles, gallons, and metric units. Minor discrepancies may occur due to rounding but are generally negligible.
Can I convert any mpg value to litres per 100 km with this formula?
Yes, the formula applies universally for any mpg value. Simply input the number, and it will give you the litres per 100 km. The calculation is based on fixed conversion factors, making it reliable across different mpg figures.
Why is the conversion factor 235.214583?
This specific number results from multiplying 100 km divided by 1.60934 (miles to km), then dividing 1 gallon (3.78541 litres), which simplifies to approximately 235.214583. It standardizes the conversion process between imperial and metric measures.
What is the difference between mpg and litres per 100 km?
MPG measures miles per gallon, indicating how many miles a vehicle can travel on one gallon of fuel. Litres per 100 km express fuel consumption in metric units, showing how many litres are used to travel 100 km. They are inverse measures of fuel efficiency.
How do I convert litres per 100 km back to mpg?
To convert litres per 100 km into mpg, use the formula: mpg = 235.214583 / (litres per 100 km). This reverses the process, translating metric consumption into imperial miles per gallon for comparison or analysis.
