What does mile/gallon (US) measure?

Mile/gallon (US) measures fuel economy as the number of statute miles a vehicle can travel per one U.S. gallon of fuel consumed.

Why convert mile/gallon to liter/100 km?

Converting between these units helps compare fuel consumption metrics used in the U.S. customary and metric systems, improving understanding of vehicle efficiency in different markets.

Is the conversion exact for all vehicles?

The conversion applies to standard units but real-world fuel consumption varies with driving conditions, vehicle types, and maintenance.
