Quick values

Liters per 100 km to MPG: compare vehicle efficiency across standards

Convert between the two most common fuel economy measures. Liters per 100 km (lower is better) and miles per gallon (higher is better) represent the same concept in opposite directions.

Formula

The formula is MPG = 235.214583 ÷ (L/100km). Divide 235.214583 by the liter-per-100km value to get miles per gallon.

Worked example

8 L/100km = 235.214583 ÷ 8 = 29.4 MPG. A car using 8 liters per 100 kilometers gets about 29.4 miles per gallon.

Common Reference Values

4.0 L/100km58.8 MPG (US)
6.0 L/100km39.2 MPG (US)

10 L/100km23.52 MPG (US)
12 L/100km19.6 MPG (US)

Practical guidance

Understanding the inverse relationship

With L/100km, lower numbers mean better efficiency. With MPG, higher numbers mean better efficiency. A car that uses 5 L/100km is more efficient than one that uses 10 L/100km. That same car gets 47 MPG, which is also better than 23.5 MPG.

Car shopping across borders

When comparing vehicles from different markets, you need both numbers. A European rating of 6 L/100km equals 39.2 MPG — excellent by most standards.

Mistake: treating them as proportional

Doubling L/100km halves MPG, but the relationship is not linear. Going from 5 to 10 L/100km drops MPG from 47 to 23.5. The change is more dramatic at lower consumption values.
