What does gallon (US)/horsepower represent?

It is a ratio expressing volume of fuel in US gallons per unit of mechanical power in horsepower, often used to measure volumetric fuel consumption relative to power output.

Why convert gallon (US)/horsepower to kilojoule per cubic meter?

Converting allows evaluating fuel efficiency in terms of energy density, facilitating comparison of energy content per volume for better fuel management and engineering analysis.

Can I use this conversion without a time basis?

While the raw conversion is possible, practical applications often require a time component, such as gallons per horsepower-hour, for meaningful fuel consumption insights.
