How do you convert l/100km to km/l?

To convert l/100km (L/100km) to km/l (km/L), apply the conversion formula: km/L = 100 / (L/100km). For example, 8 L/100km converts to 12.5 km/L.

What is 8 l/100km in km/l?

8 l/100km (8 L/100km) is equal to 12.5 km/l (12.5 km/L).

Which is larger, 1 liters per 100 km (L/100km) or 1 kilometers per liter (km/L)?

At an input of 1 L/100km, the equivalent value is 100 km/L, whereas 1 km/L equals 100 L/100km. Because fuel economy scales use offset or reciprocal relationships, always check the specific operating range in the conversion table above.

How do I convert back from km/l (km/L) to l/100km (L/100km)?

Use the Swap button in the calculator above to switch km/L and L/100km immediately. For reference, 1 km/L equals 100 L/100km.

Are there regional or standard differences when converting L/100km and km/L?

US vs. UK MPG and Inverse Consumption Scales: Miles per gallon (MPG) measures distance traveled per unit of fuel (higher is better), whereas Liters per 100 km (L/100km) measures fuel volume consumed over a fixed distance (lower is better). Because the UK Imperial gallon (4.54609 L) is ~20.1% larger than the US gallon (3.78541 L), US MPG uses the conversion constant 235.215 while UK MPG uses 282.481.

How to Convert L/100km to km/L

To convert l/100km (L/100km) to km/l (km/L), apply the governing fuel efficiency relationship: km/L = 100 / (L/100km).

Use this formula to convert between l/100km and km/l:

km/L = 100 / (L/100km)

Fuel consumption and distance-per-volume efficiency scales are related by exact international volume and mile/kilometer constants.

For example, here's how to convert 8 L/100km to km/l using the formula above:

km/l = 100 ÷ 8 = 12.5 = 12.5 km/L

How Many km/L Are in a Liters per 100 km?

There are 100 km/l in a liters per 100 km, which is why we use this value in the formula above.

1 L/100km = 100 km/L|1 km/L = 100 L/100km

Our liters per 100 km to kilometers per liter calculator automatically converts your fuel economy measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.

L/100km and km/l are both units used to measure fuel economy. Keep reading to learn more about each unit.

What Is a Liters per 100 km?

Liters consumed per 100 kilometers traveled. It serves as a primary reference unit for measuring fuel economy across scientific and practical applications. [1]

The liters per 100 km is classified as a metric and SI-compatible unit of fuel economy. L/100km can be abbreviated as L/100km; for example, 1 liters per 100 km can be written as 1 L/100km.

When working with l/100km (L/100km) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.

In practice, l/100km (L/100km) are widely used across standard fuel economy applications within SI metric workflows, engineering documentation, and technical data sheets.

What Is a Kilometers per Liter?

Kilometers traveled per liter of fuel. It serves as a primary reference unit for measuring fuel economy across scientific and practical applications. [2]

The kilometers per liter is classified as a metric and SI-compatible unit of fuel economy. km/L can be abbreviated as km/L; for example, 1 kilometers per liter can be written as 1 km/L.

In the metric system, "kilo" is the standard SI prefix for thousands, or 10³. This makes the kilometers per liter (km/L) a convenient decimal multiple of the miles per gallon (MPG (US)).

In practice, km/l (km/L) are widely used across standard fuel economy applications within SI metric workflows, engineering documentation, and technical data sheets.

Learn more about km/l in our Fuel Economy Converter.

When converting fuel economy between l/100km (L/100km) and km/l (km/L), keep full floating-point precision (1 L/100km = 100 km/L; 1 km/L = 100 L/100km) during intermediate calculations and round only the final kilometers per liter figure to match your instrument tolerance.
