Example: 12 km/L → 12 × 2.35215 = 28.2 mpg (US)
km/L and mpg are both “higher is better” range-per-fuel metrics, so the conversion between them is a simple linear multiplication: mpg (US) = km/L × 2.35215.
A 10 km/L car (common for larger Asian-market vehicles) gets 23.5 mpg; a 15 km/L compact reaches 35.3 mpg; a 20 km/L hybrid hits 47 mpg. This is the most straightforward petrol conversion because no inversion is involved.
The constant 2.35215 comes from 3.785411784 L/gal ÷ 1.609344 km/mi. For UK mpg the constant is 2.82481 because the imperial gallon (4.546 L) is 20% larger than the US gallon.
12 × 2.35215 = 28.2 mpg (US).
Both km/L and mpg are range units — bigger numbers mean better efficiency. Multiplying one proportional scale by a constant gives another proportional scale. L/100km is a consumption unit, which requires inversion.
Yes. Japan uses the standard metric litre (1000 mL) and kilometre, so km/L figures are directly comparable regardless of country.
