Liters/100 km to Miles Per Gallon Converter

This online calculator converts fuel consumption expressed as liters per 100 kilometers (L/100 km) to miles per U.S. gallon (MPG, US). L/100 km is a metric fuel-consumption metric (lower = better). MPG (US) measures distance per unit of fuel (higher = better).

How to use the tool

1. Enter the fuel consumption value in liters per 100 km (example: 6.5).
2. Set the number of decimal places for the result if needed.
3. Press Convert. The tool computes MPG (US) and shows the calculation step.
4. Use Copy Result to copy the numeric MPG value to clipboard.
5. Use Reset to clear inputs and return to default decimal precision.
6. The tool validates input: value must be numeric and greater than zero.

Definitions of the units

Liters per 100 kilometers (L/100 km)

Abbreviation: L/100 km. System: SI-derived metric. Definition: volume of fuel (liters) consumed to travel 100 kilometers. Example relation for this converter: 1 L/100 km ≡ 235.214583 MPG (US) when inverted by the standard formula below. One liter is 1.0 L. Use-case: common in Europe, Canada, Australia and many other markets to report vehicle fuel consumption. Notes: Lower L/100 km means higher efficiency.

Miles per U.S. gallon (MPG, US)

Abbreviation: mpg or MPG (US to disambiguate from Imperial gallon). System: US customary (distance per fuel volume). Definition: number of statute miles a vehicle travels on one U.S. liquid gallon (1 US gallon = 3.785411784 L). Relation used here: MPG (US) = 235.214583 ÷ (L/100 km). Use-case: widely used in the United States and commonly shown on EPA labels.

Real-world examples (exact published combined ratings)

Notes: examples use manufacturer or official WLTP/EPA combined figures published by manufacturers or official brochures. These are the published combined consumption numbers for the specified model/trim at the time those documents were published; conditions and test procedures differ by region. Each example shows the exact source.

1. 2021 Toyota Prius (combined rating listed as 4.4 L/100 km). Converted: 4.4 L/100 km → 53.46 MPG (US).
2. 2021 Toyota Corolla Hatchback Hybrid (combined WLTP listed as 4.4 L/100 km). Converted: 4.4 L/100 km → 53.46 MPG (US).
3. Volkswagen Golf 1.5 TSI (example combined WLTP figure: 5.5 L/100 km). Converted: 5.5 L/100 km → 42.76 MPG (US).
4. 2021 Honda Civic (example combined WLTP reference 6.0 L/100 km for some trims). Converted: 6.0 L/100 km → 39.20 MPG (US). 
5. 2021 Ford Focus (example combined WLTP entry for certain trims ~5.1 L/100 km). Converted: 5.1 L/100 km → 46.12 MPG (US). Source: Ford technical brochure and specification sheets.
6. Toyota Prius Prime (EPA combined example ~5.6 L/100 km equivalent; converted value shown for reference). Converted: 5.6 L/100 km → 42.00 MPG (US).
7. Honda Clarity (published combined fuel consumption example 5.6 L/100 km for some powertrains). Converted: 5.6 L/100 km → 42.00 MPG (US).
8. Volkswagen Golf Variant 1.5 TSI Active (combined WLTP example 5.5 L/100 km). Converted: 5.5 L/100 km → 42.76 MPG (US).
9. Toyota Corolla Touring Sports (hybrid example combined 4.7 L/100 km). Converted: 4.7 L/100 km → 50.05 MPG (US).
10. Volkswagen Golf (example combined WLTP 5.5 L/100 km for certain trims). Converted: 5.5 L/100 km → 42.76 MPG (US).

Notes on accuracy and variability

Official published figures come from test cycles (WLTP, EPA) that use standardized procedures. Real-world consumption can vary with driving style, load, terrain, maintenance and environmental conditions. Use published combined ratings only as a standard reference point.
