Show the working
  1. 1 hp = 2544.43357764 BTU/h
  2. 1 × 2544.43357764 = 2544.43357764 BTU/h

How to convert horsepower to btu (it) per hour

1 hp = 2,544.43357764 BTU/h, so multiply by 2,544.43357764 to go from horsepower (mechanical, 550 ft·lbf/s) to BTU (IT) per hour. Going the other way, 1 BTU/h = 0.000393014778922 hp.

BTU/h = hp × 2,544.43357764
hp = BTU/h × 0.000393014778922

Worked example:

1 hp = 2544.43357764 BTU/h
5 × 2544.43357764 = 12722.1678882 BTU/h
