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

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

What is 12.5 km/l in l/100km?

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

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

At an input of 1 km/L, the equivalent value is 100 L/100km, whereas 1 L/100km equals 100 km/L. 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 l/100km (L/100km) to km/l (km/L)?

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

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

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 km/L to L/100km

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

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

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

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 12.5 km/L to l/100km using the formula above:

l/100km = 100 ÷ 12.5 = 8 = 8 L/100km

How Many L/100km Are in a Kilometers per Liter?

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

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

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

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

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. [1]

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.

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. [2]

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.

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

Quick Info

Direct Factor: 1 kilometers per liter (km/L) equals 100 l/100km (L/100km).
Inverse Factor: 1 liters per 100 km (L/100km) equals 100 km/l (km/L).
Formula: L/100km = 100 / (km/L).
Standard Note: 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.
