About Liters per 100 miles and Miles per Gallon (US)
Liters per 100 miles mixes metric fuel volume with mile distances, a hybrid unit appearing in some North American EV and plug-in hybrid comparisons alongside gallons-per-100-miles figures. Miles per US gallon measures distance per fuel. Higher is better. It is the EPA window-sticker figure on every new car sold in the United States. The two scales are related by the formula mpg = 378.541295 / L/100mi. Liters per 100 miles is used in EV and hybrid consumption comparisons and in mixed-unit fleet reporting. Miles per Gallon (US) is used in US car shopping and EPA ratings.
Precision and Rounding:Fuel economy units are reciprocal of each other: consumption (L/100 km) falls as efficiency (mpg, km/L) rises, so conversions are formula-based, not simple factors, and small mpg differences matter more at low values than high ones. One decimal place is standard for window stickers and trip computers.
Fuel-economy results use exact volume and distance definitions with the reciprocal formulas shown on each page (reference).
