How to Convert MPG (US) to L/100km
MPG (US) and L/100km have an inverse (reciprocal) relationship — one measures how far you go per unit of fuel (efficiency), while the other measures how much fuel is needed per distance (consumption).
To convert, the value is first expressed as km/L, then the target unit's formula is applied. A higher mpg value corresponds to a lower L/100km value (better economy in both cases).
Example: 30 MPG (US) ≈ 7.84048072 L/100km
