About Converting Liters per kilometer to Miles per US gallon
Liters per kilometer and Miles per US gallon are two of the ways the world measures fuel efficiency, and converting between them is essential for comparing a US car's window-sticker rating to a European or Asian one. Specifically: Liters per kilometer fuel economy unit, and miles per US gallon fuel economy unit.
Formula
Fuel economy formulas invert between distance-per-volume and volume-per-distance units as needed.
Efficiency-style units (like mpg or km/L) and consumption-style units (like L/100 km) measure the same underlying thing from opposite directions, so converting between the two families requires a reciprocal, not just a multiplication factor.
Simple example
1 L/km × 2.352146e-12 = 2.352145833 mpg
1 liters per kilometer = 2.352145833 miles per us gallon.
Real-world example
30 L/km × 2.352146e-12 = 0.0784048611 mpg
30 liters per kilometer = 0.0784048611 miles per us gallon.
