L/100 Km to Gal/100 Mi (US) (L/100 km to gal/100 mi)
1 liter per 100 kilometers equals 0.4251437074 gallons (US) per 100 miles (rounded).
How to convert liters per 100 kilometers to gallons (US) per 100 miles
To convert liters per 100 kilometers to gallons (US) per 100 miles, multiply the number of liters per 100 kilometers by 0.4251437074. The factor is rounded to 10 significant digits. To go the other way, multiply gallons (US) per 100 miles by 2.352145833 (rounded).
gallons (US) per 100 miles = liters per 100 kilometers × 0.4251437074
Example: 10 liters per 100 kilometers = 4.251437074 gallons (US) per 100 miles.
Miles per gallon rises as a car gets more efficient, while liters per 100 km falls. The conversion between them is a reciprocal (for US mpg: L/100 km = 235.215 ÷ mpg).
About these units
Liter Per 100 Kilometers (L/100 km)
Fuel used to travel 100 kilometers. The standard fuel-economy unit in Europe, Canada, Australia and China; lower is better.
Where miles per gallon asks how far you go, litres per 100 km asks how much you burn. Consumption is the reciprocal of economy, so it behaves linearly: if two cars each drive 100 km, the one that uses 8 litres instead of 10 saves exactly 2 litres, whatever the starting point. The sources I found do not name an inventor or date for the unit, but it is the standard in much of Europe, Africa, Australia, New Zealand, Canada and China.
Lower is better, which surprises people used to mpg. The relationship between the two scales is a reciprocal: for US mpg, L/100 km equals 235.215 divided by mpg. The Smart Fortwo cdi at about 3.4 L/100 km works out to roughly 69 mpg (US), while a full-size SUV in the US averages around 16 mpg on the highway, which is about 14.7 L/100 km. The US EPA introduced gallons per 100 miles, which carries the same logic, to counter the MPG illusion and make comparisons fairer.
1 liter per 100 kilometers = 100 kilometers per liter (exactly).

Gallon (US) Per 100 Miles (gal/100 mi)
US gallons used per 100 miles. Proposed in the US as a more intuitive way to compare efficiency than miles per gallon.
Gallons per 100 miles flips the familiar miles-per-gallon figure upside down, so that lower numbers mean a more efficient vehicle. New US window stickers have shown it next to mpg since the EPA's 2011 labeling rule, which became mandatory for model year 2013. The label estimates how much fuel or electricity a car needs to cover 100 miles.
The reason is the so-called MPG illusion. Fuel use per mile is the reciprocal of mpg, so equal gains in mpg do not save equal fuel. Lifting a car from 10 to 20 mpg doubles its efficiency, while lifting another from 50 to 60 mpg improves it by only 20 percent, even though each gains 10 mpg.
The unit is the same measure as liters per 100 kilometers used in much of the world. One gallon per 100 miles equals about 2.352 L per 100 km, and the converter stores it as kilometers per liter, so a value x gal/100 mi corresponds to 42.514 divided by x km/L. That is also why a reading of zero has no meaning.
1 gallon (US) per 100 miles = 42.51437074 kilometers per liter (approximately).
