What this conversion means in practice
Lower L/100 km means better efficiency; higher MPG means better efficiency, the intuitions pull in opposite directions. Converting MPG (US) to L/100 km lets you situate a US window sticker next to an EU brochure without gross errors.
The headline factor for a single unit step is 1 MPG (US) = 235.214583333333 L/100 km, computed through the same meters-per-liter internal base as the full fuel consumption converter.
How this pair maps through the internal base
Values are normalized to meters per liter, then expanded into the target unit. Reciprocal-style rows (liters per distance) invert through that base exactly like the interactive converter, no shortcut formulas here that disagree with the dropdown tool.

US miles per gallon to Liters per 100 kilometers FAQ
MPG (US) to L/100 km for import buyers and fleet analysts.
How do I convert MPG (US) to L/100 km?
Fuel economy units mix distance-per-volume and volume-per-distance forms. This page applies the same forward and inverse rules as the full fuel consumption converter, multiply and divide through the shared base (meters per liter) automatically.
Why is L/100 km not the reciprocal of MPG without extra steps?
Liters per 100 kilometers is consumption (fuel per distance), while MPG is economy (distance per fuel). Our engine converts both to the same internal base before comparing, matching the dropdown converter.
Which gallon and mile definitions are used?
US MPG uses the US liquid gallon (3.785411784 L) and the international mile (1609.344 m), consistent with CalcRegistry’s fuel converter documentation.
