How this system works

James Watt’s horsepower was later fixed at 550 foot-pounds per second (about 745.7 W). Metric horsepower (Pferdestärke) is 75 kilogram-force metres per second, 735.5 W. Boiler and HVAC work still quotes BTU/h and tons of refrigeration.

Base unit: watt. Kilowatt is Metric; Horsepower (mechanical) is US customary.
