How to Convert L/100km to MPG
To convert l/100km (L/100km) to mpg (MPG (UK)), apply the governing fuel efficiency relationship: MPG (UK) = 282.481 / (L/100km).
Use this formula to convert between l/100km and mpg:
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 6 L/100km to mpg using the formula above:
How Many MPG Are in a Liters per 100 km?
There are 282.4809363 mpg in a liters per 100 km, which is why we use this value in the formula above.
Our liters per 100 km to miles per gallon calculator automatically converts your fuel economy measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
L/100km and mpg 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 Miles per Gallon?
Miles traveled per UK Imperial gallon. It serves as a primary reference unit for measuring fuel economy across scientific and practical applications. [2]
The miles per gallon is classified as a US customary and imperial unit of fuel economy. MPG can be abbreviated as MPG (UK); for example, 1 miles per gallon can be written as 1 MPG (UK).
When working with mpg (MPG (UK)) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, mpg (MPG (UK)) are widely used across standard fuel economy applications within US customary and imperial workflows, engineering documentation, and technical data sheets.
When converting fuel economy between l/100km (L/100km) and mpg (MPG (UK)), keep full floating-point precision (1 L/100km = 282.4809363 MPG (UK); 1 MPG (UK) = 282.4809363 L/100km) during intermediate calculations and round only the final miles per gallon figure to match your instrument tolerance.
