How to convert fuel economy on this page
- Enter the value on the top left; read the converted figure on the top right.
- Tap MPG (US), L/100 km, or km/L under From and To, or use Swap units ⇄.
- Try shortcuts such as 30 MPG → L/100 km or 6 L/100 km → MPG.
MPG (US) and km/L: higher = better. L/100 km: lower = better. Formula: L/100 km ≈ 235.2 ÷ MPG (US). Road-trip distance? Use the length converter; more tools on everyday calculators and unit converters.
Cross-border car shopping
A European brochure lists 5.5 L/100 km—convert to ~43 MPG (US) here before comparing to a US 32 MPG sticker on another model.
Trip planning
Estimate fuel used: (distance in km ÷ 100) × L/100 km. Get distance from the length converter (miles ↔ km).
Sticker vs dashboard
EPA/combined cycle numbers often differ from your commute—this tool converts units, not driving style.
How do you convert 30 MPG to L/100 km?
About 7.84 L/100 km (235.2 ÷ 30). Enter 30, MPG (US) → L/100 km, or tap the 30 MPG shortcut.
How do you convert 25 MPG to liters per 100 km?
25 MPG ≈ 9.41 L/100 km. Use the 25 MPG → L/100 km shortcut or pick units yourself.
What is 8 L/100 km in MPG?
8 L/100 km ≈ 29.4 MPG (US) (235.2 ÷ 8). Enter 8, L/100 km → MPG (US).
What is 6 L/100 km in MPG?
6 L/100 km ≈ 39.2 MPG (US)—very efficient by US standards. Tap the 6 L/100 km shortcut.
MPG to L/100 km formula?
L/100 km = 235.214583 ÷ MPG (US gallon). Reverse: MPG = 235.214583 ÷ L/100 km. This page applies the full constant.
How do you convert km/L to MPG?
Convert km/L → L/100 km first (100 ÷ km/L), then to MPG, or pick km/L → MPG (US) directly. Example: 15 km/L ≈ 35.3 MPG.
US MPG vs UK MPG—same number?
No—UK imperial gallons are larger, so UK MPG is higher for the same car. This calculator uses US MPG only.
40 MPG to L/100 km?
40 MPG ≈ 5.88 L/100 km. Try the 40 MPG → km/L shortcut for another view (~16.8 km/L).
Is 30 MPG good fuel economy?
In the US, ~30 MPG (US) is often decent for mixed driving; hybrids and diesels can beat it. Compare using the same unit after converting European L/100 km labels.
Electric MPGe or kWh/100 km?
Not on this page—MPGe and kWh/100 km need an EV-specific tool. This converter is for gasoline/diesel volume economy units.
50 MPG to L/100 km?
50 MPG ≈ 4.70 L/100 km. Enter 50, MPG → L/100 km.
10 L/100 km in MPG?
10 L/100 km ≈ 23.5 MPG (US)—common for larger vehicles.
20 km/L to L/100 km?
20 km/L = 100 ÷ 20 = 5.0 L/100 km. Swap km/L and L/100 km on the form.
Diesel vs gasoline L/100 km?
Volume converts the same; energy per liter differs—compare fuels only after converting units, not chemistry.
