Liters per 100km to Miles per Gallon (US) Formula & Unit Definitions
Because the conversion between volume-per-distance (L/100km) and distance-per-volume (mpg US) is an inverse mathematical curve, the relationship is symmetrical. The constant 235.214583 is derived from 100 km divided by the miles-per-kilometer and liters-per-gallon conversion ratios. Dividing 235.215 by any L/100km rating yields the exact US Miles per Gallon equivalent: MPG (US) = 235.215 ÷ (L/100km).
Quick Estimation: Quick mental shortcut: To convert L/100km to US MPG in your head, divide 240 by the L/100km value. For example, 240 ÷ 8 L/100km = 30 mpg US (exact: 29.40 mpg US); 240 ÷ 6 L/100km = 40 mpg US (exact: 39.20 mpg US).

Frequently Asked Questions
Q.How do you convert L/100km to US MPG?
Divide 235.215 by your L/100km value: MPG (US) = 235.215 / (L/100km).
Q.What is the reverse conversion from US MPG to L/100km?
To convert back, use the MPG US to L/100km Converter where L/100km = 235.215 / MPG (US).
Q.What is 8 L/100km in US MPG?
8 L/100km equals approximately 29.40 US MPG.
Q.What is a good L/100km rating for a car?
Under 6.0 L/100km is considered excellent efficiency (over 39 US MPG), typical of hybrids and clean diesels.
Q.Why is the conversion formula the same in both directions?
Because distance per volume and volume per distance are inverse quantities, so f(x) = C/x is its own mathematical inverse.
