About Converting Meters per liter to Liters per 100 kilometers
Meters per liter and Liters per 100 kilometers are two of the ways the world measures fuel efficiency, and converting between them is essential for comparing a US car's window-sticker rating to a European or Asian one. Specifically: Meters per liter fuel economy unit, and liters per 100 kilometers fuel economy unit.
Formula
Fuel economy formulas invert between distance-per-volume and volume-per-distance units as needed.
Efficiency-style units (like mpg or km/L) and consumption-style units (like L/100 km) measure the same underlying thing from opposite directions, so converting between the two families requires a reciprocal, not just a multiplication factor.
Simple example
1 m/L × 100000000000 = 100,000 L/100 km
1 meters per liter = 100,000 liters per 100 kilometers.
Real-world example
30 m/L × 100000000000 = 3,333.333333 L/100 km
30 meters per liter = 3,333.333333 liters per 100 kilometers.
Conversion table
| Meters per liter (m/L) | Liters per 100 kilometers (L/100 km) |
|---|---|
| 10 m/L | 10,000 L/100 km |
| 20 m/L | 5,000 L/100 km |
| 30 m/L | 3,333.333333 L/100 km |
| 40 m/L | 2,500 L/100 km |
| 50 m/L | 2,000 L/100 km |
| 60 m/L | 1,666.666667 L/100 km |
Reverse conversion: Liters per 100 kilometers to Meters per liter
1 L/100 km × 1e-11 = 100,000 m/L
1 liters per 100 kilometers = 100,000 meters per liter.
Fuel economy formulas invert between distance-per-volume and volume-per-distance units as needed.

Meters per liter fuel economy unit.
Understanding the Liters per 100 kilometers
Liters per 100 kilometers (L/100 km) measures fuel consumption. Liters per 100 kilometers measures fuel consumed to travel 100 km — lower values mean better efficiency, the reverse convention from mpg/km-per-L. It is classified as a Metric unit.
Where it's used: Standard fuel-economy unit across most of Europe, Canada, Australia, and elsewhere
Uses of the Liters per 100 kilometers today
- Official vehicle fuel-consumption labeling across most of the world outside the US
- European and Canadian vehicle efficiency standards and taxation
History of the Liters per 100 kilometers
L/100km inverts the 'efficiency' framing of mpg/km-per-L into a 'consumption' framing (how much fuel is used for a fixed distance), which many transport agencies consider more intuitive for comparing costs and emissions — it became the standard EU fuel-labeling metric as part of vehicle emissions and efficiency regulations from the late 20th century onward.
Historical origin. Liters per 100 kilometers was not the invention of a single named person; it developed through the process described above.
Liters per 100 kilometers — sources
- European Commission — Fuel Economy Labelling Directive — Basis for L/100km as the standard EU fuel-consumption metric.

Frequently asked questions
How many liters per 100 kilometers are in 1 meters per liter?
1 meters per liter equals 100,000 liters per 100 kilometers, using the exact defined conversion factor rather than an estimate.
How do I convert meters per liter to liters per 100 kilometers?
Fuel economy units sometimes need inversion rather than simple multiplication — the converter above and the formula section handle this automatically.
How do I convert liters per 100 kilometers back to meters per liter?
Use the reverse factor: 1 liters per 100 kilometers equals 100,000 meters per liter. You can also use the swap control in the converter above to flip the direction instantly.
What is a meters per liter?
Meters per liter (m/L) is a unit of fuel economy.
What is a liters per 100 kilometers?
Liters per 100 kilometers (L/100 km) measures fuel consumption. Liters per 100 kilometers measures fuel consumed to travel 100 km — lower values mean better efficiency, the reverse convention from mpg/km-per-L. It is classified as a Metric unit.
Is the meters per liter to liters per 100 kilometers conversion exact?
Yes. Both meters per liter and liters per 100 kilometers are defined by fixed standards rather than physical artifacts, so the factor of 100000000000 used above is exact to as many digits as you choose to display.
