What does Btu (th)/minute measure?

Btu (th)/minute measures the rate of thermal energy flow, representing heat transferred per minute in thermal systems.

What is horsepower (550 ft*lbf/s)?

Horsepower (550 ft*lbf/s) is an imperial unit of mechanical power, defined as 550 foot-pound-force per second, commonly used to rate engines and motors.

Can I use this conversion for precise engineering calculations?

This conversion is useful for comparisons and general estimates, but real-world applications should consider energy losses and efficiency since thermal and mechanical powers are different.
