What Is Liters per 100 Kilometers (L/100km)?
Liters per 100 kilometers (L/100km) is the standard unit used in Canada to measure fuel consumption. It shows how many liters of fuel a vehicle uses to travel 100 kilometers.
In this system, a lower number means better fuel efficiency, because the vehicle uses less fuel to travel the same distance.
For example:
A car that uses 6 L/100km is more fuel-efficient than a car that uses 10 L/100km. This unit is widely used across Canada for:
- Fuel economy ratings
- Vehicle comparisons
- Government fuel efficiency standards
- Car dealership listings
What Is Miles Per Gallon (MPG)?
Miles per gallon (MPG) is a fuel efficiency measurement used in the imperial system, most commonly in the United States. It shows how many miles a vehicle can travel using one gallon of fuel.
In this system, a higher number means better fuel efficiency, because the vehicle can travel farther on less fuel.
For example:
A car with 40 MPG is more efficient than a car with 25 MPG.
Because many vehicles are marketed in North America using MPG—especially from the U.S.—Canadians often need to convert between MPG and L/100km to make accurate comparisons.
How to Convert L/100km to MPG
To convert liters per 100 kilometers to miles per gallon, you use a simple formula:
- MPG = 235.215 ÷ (L/100km)
Example conversions:
- 5 L/100km = 47.04 MPG
- 7 L/100km = 33.60 MPG
- 8.5 L/100km = 27.67 MPG
- 10 L/100km = 23.52 MPG
Because this formula involves division, using a calculator like this makes the process much faster and more accurate.
How to Convert MPG to L/100km
To convert miles per gallon back to liters per 100 kilometers, you reverse the formula:
- L/100km = 235.215 ÷ MPG
Example conversions:
- 20 MPG = 11.76 L/100km
- 30 MPG = 7.84 L/100km
- 40 MPG = 5.88 L/100km
If you frequently compare vehicles from Canada and the U.S., it’s useful to have both conversion tools available.
What’s the Difference Between Metric and Imperial Systems?
The metric and imperial systems measure fuel efficiency in completely different ways, which can be confusing at first.
Metric System (used in Canada):
- Measures fuel used over distance
- Uses liters per 100 kilometers (L/100km)
- Lower numbers = better efficiency
Imperial System (used in the U.S.):
- Measures distance traveled per fuel used
- Uses miles per gallon (MPG)
- Higher numbers = better efficiency
Because these systems are inverse of each other, the numbers don’t translate directly, which is why conversion tools are essential.
Does Canada Use L/100km or MPG?
Canada officially uses the metric system, so fuel economy is displayed in liters per 100 kilometers (L/100km).
However, MPG is still widely used in:
- U.S. car advertisements
- Online car reviews
- Imported vehicle specifications
- Cross-border comparisons
This means Canadians often need to convert between the two systems when researching or buying a vehicle.
Where Is This Conversion Commonly Used?
L/100km to MPG conversion is commonly used in many everyday situations in Canada:
Buying a Car: Comparing Canadian fuel ratings with U.S. listings requires quick conversion.
Cross-Border Shopping: Many Canadians buy vehicles or check specs from U.S. websites that use MPG.
Fuel Cost Planning: Understanding fuel efficiency helps estimate long-term fuel costs.
Car Reviews & Comparisons: Automotive websites often display MPG instead of L/100km.
Road Trips: Knowing fuel efficiency helps plan distance, fuel stops, and travel budgets.
ALLREVIEW Trivia – Did You Know?
- Canada switched to the metric system in the 1970s, which is why fuel efficiency is measured in L/100km.
- The number 235.215 used in the formula comes from combining kilometer-to-mile and liter-to-gallon conversions.
- European countries also use L/100km, making it a globally recognized standard.
- MPG values can differ between U.S. gallons and UK gallons, but Canada typically compares with U.S. MPG.
- Hybrid and electric vehicles often have extremely low L/100km values, making conversions even more important when comparing efficiency.
