About these units
W (watts): The SI unit of power: one joule per second.
hp (mechanical horsepower): US engine and motor rating: 550 ft·lbf per second.
Horsepower comes in several kinds: mechanical (550 ft·lbf/s, 745.7 W, used here as 'hp'), metric (PS, 735.5 W) and electrical (746 W). Cooling loads use BTU/h and the refrigeration ton (12,000 BTU/h).
