Convert L/100 km to MPG (US)

Enter fuel economy as liters per 100 kilometers [L/100 km] to obtain us miles per gallon [MPG (US)], or vice versa.

7.350455729167

Formula: 1 L/100 km = 235.214583333333 MPG (US)

What this conversion means in practice

European brochures quote L/100 km; US shoppers think MPG. Translate consumption-style units back to MPG (US) with the same definitions as the full fuel-consumption converter.

The headline factor for a single unit step is 1 L/100 km = 235.214583333333 MPG (US), 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.

Liters per 100 kilometers to US miles per gallon FAQ

L/100 km to MPG (US): reciprocal intuition and rounding for highway estimates.

How do I convert L/100 km to MPG (US)?

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.
