378.541178 Liters per 100 Miles (L/100mi)
SwitchExplanation
The converter converts miles per us gallon into liters per 100 miles by normalizing the input through liters per 100 kilometers, then restating the result in the target fuel-economy format. Because one side measures consumption and the other measures efficiency, the numeric behavior is inverse even though the route stays on one fixed shared basis. The calculator, common values, and mirror Liters per 100 Miles to Miles per US Gallon page all use that same model.
Miles per US Gallon to Liters per 100 Miles is computed from one fixed fuel-economy relationship, keeping mirror routes and reference values consistent.
Calculator output and table rows stay aligned because they use the same fixed fuel-economy definitions.

Frequently Asked Questions
How is mpg (US) to L/100mi calculated?
This page converts through liters per 100 kilometers, which keeps consumption-format and efficiency-format fuel economy units on one fixed shared basis even though their numeric behavior is inverse.
Is there a reverse page for L/100mi to mpg (US)?
Yes. Use the mirror L/100mi to mpg (US) page to apply the inverse relationship with the same fixed fuel-economy definitions.
Why do consumption and efficiency values move in opposite directions?
Consumption units measure fuel used per distance, while efficiency units measure distance per fuel amount. That is why improving efficiency lowers one number while raising the other.
