Why convert from pound/Btu (th) to pound/horsepower/hour?

This conversion translates thermal fuel consumption data into mechanical fuel efficiency metrics, enabling comparison between heat-producing equipment and engines.

What industries use this conversion?

Power generation, automotive and aerospace engineering, industrial furnace and boiler design, and marine engine testing commonly use this conversion.

Can I use this conversion to compare all fuels directly?

While it helps compare fuels by mass energy content, variations in fuel types and system efficiencies mean results should be interpreted with care.
