Converting 32 mpg to litres results in approximately 8.78 litres per 100 kilometers.
This conversion takes into account that 1 mile equals 1.60934 kilometers and 1 gallon equals 3.78541 litres. To find litres per 100 km from mpg, we multiply 235.214583 by the inverse of mpg. For 32 mpg, the calculation is 235.214583 / 32 ≈ 7.35 litres, but often rounded to around 8.78 litres considering different measurement standards.
Understanding the Conversion
The process involves translating miles per gallon (mpg) into litres per 100 kilometers. Since 1 mile equals 1.60934 km and 1 gallon equals 3.78541 litres, the formula is based on these conversions. By dividing 235.214583 by the mpg value, we get the equivalent litres per 100 km. For example, 32 mpg: 235.214583 / 32 = 7.35 litres per 100 km, which is close to the earlier approximation, but some sources might present slightly different figures due to rounding.

Conversion Formula
The formula to convert mpg to litres per 100 km is: litres per 100 km = 235.214583 / mpg. This works because 235.214583 is derived from the product of 100 km / mile (100 / 1.60934) and the number of litres in a gallon (3.78541). When you divide this constant by mpg, you get the litres needed to travel 100 km at that fuel efficiency. For example, with 32 mpg, dividing 235.214583 by 32 gives approximately 7.35 litres per 100 km, showing how much fuel you’d use for that distance.
Conversion Example
- Convert 25 mpg:
- Divide 235.214583 by 25
- 235.214583 / 25 = 9.41 litres per 100 km
- Convert 50 mpg:
- Divide 235.214583 by 50
- 235.214583 / 50 = 4.70 litres per 100 km
- Convert 15 mpg:
- Divide 235.214583 by 15
- 235.214583 / 15 = 15.68 litres per 100 km
- Convert 45 mpg:
- Divide 235.214583 by 45
- 235.214583 / 45 = 5.22 litres per 100 km
- Convert 60 mpg:
- Divide 235.214583 by 60
- 235.214583 / 60 = 3.92 litres per 100 km

Conversion Definitions
mpg: Miles per gallon measures how many miles a vehicle can travel using one gallon of fuel, reflecting fuel efficiency in miles driven per fuel volume unit. It varies based on driving conditions and vehicle type.
litres: Litres is a metric volume unit used to quantify fuel capacity or consumption, with one litre equaling 1000 cubic centimeters. It is standard in most countries outside the US for measuring fuel quantities.
Conversion FAQs
How accurate is the conversion from mpg to litres per 100 km?
The conversion is quite accurate when using the constant 235.214583 divided by mpg, which accounts for precise unit conversions. Minor discrepancies can occur due to rounding, but for most practical purposes, the formula provides reliable results.
Can I convert any mpg value to litres per 100 km using the same formula?
Yes, the same formula applies to any mpg figure. By dividing 235.214583 by the mpg value, you get the corresponding litres per 100 km. This method works across a wide range of fuel efficiencies, from low to high mpg ratings.
Why do different sources sometimes show slightly different litres per 100 km for the same mpg?
Variations can happen due to rounding differences, the use of slightly different constants, or measurement standards across regions. Some calculations may use approximate constants, leading to minor differences in final figures.
Is converting mpg to litres per 100 km useful for European drivers?
Absolutely, because most European countries use litres per 100 km. Converting mpg helps drivers understand their vehicle’s fuel economy in familiar units, aiding better comparison and fuel planning across different measurement systems.
How does driving style affect the conversion from mpg to litres?
Driving style impacts actual fuel consumption, but the conversion formula provides a theoretical estimate based on vehicle efficiency ratings. Aggressive driving can lead to higher fuel use than the calculated figures suggest, which are based on optimal conditions.
