Definitions

Liters per 10 kilometers (L/mil)

Liters consumed per Swedish mil (10 km).

Liters per mil is a fuel consumption unit used primarily in Sweden and Norway, where 'mil' refers to a metric mile of 10 kilometers.

Liters per 100 kilometers (L/100 km)

European standard for fuel economy.

Liters per 100 kilometers (L/100km) is the standard method for measuring fuel consumption in most of Europe, Canada, and Australia. A lower number indicates better fuel economy.

Miles per gallon (US) (mpg (US))

US standard fuel economy (using US Gallons).

Miles per gallon (MPG) is the standard unit for fuel economy in the United States. It measures how far a vehicle can travel on one US gallon of fuel. A higher number indicates better efficiency. Note that the US gallon is smaller than the UK gallon.

Miles per gallon (UK) (mpg (UK))

UK standard fuel economy (using Imperial Gallons).

Miles per gallon (MPG) is also used in the UK, but it is based on the Imperial gallon, which is about 20% larger than the US gallon. Therefore, MPG values in the UK appear higher than in the US for the same efficiency.

Frequently asked questions

What is the difference between L/100 km and km/L?

L/100 km is liters used per 100 km (lower is better). km/L is distance per liter (higher is better). You can convert with: km/L = 100 ÷ (L/100 km).

How do I convert L/100 km to US mpg?

Use: US mpg = 235.215 ÷ (L/100 km). Example: 7.0 L/100 km ≈ 33.6 mpg (US).

How do I convert L/100 km to UK mpg?

Use: UK mpg = 282.481 ÷ (L/100 km). Example: 7.0 L/100 km ≈ 40.4 mpg (UK).

Why is UK mpg different from US mpg?

The gallon sizes differ. A UK (imperial) gallon is about 4.546 L, while a US gallon is about 3.785 L, so UK mpg numbers are higher.

How do I calculate fuel cost for a trip?

Liters needed = (distance_km ÷ 100) × (L/100 km). Then cost = liters × price per liter.

Why does my fuel economy look “wrong” after converting?

Because some units invert the meaning (L/100 km vs mpg). Lower L/100 km is better, but higher mpg is better—so the number changes direction.

How do I use the fuel consumption converter on konvertera.nu?

Enter your value (like 6.5 L/100 km), choose the unit you want (like mpg US), and konvertera.nu converts it instantly.
