How many watts are equivalent to one horsepower?

One horsepower is equivalent to 746 watts. This conversion is important in various mechanical and electrical applications, particularly in the HVAC field, where both horsepower and watts are used to measure the power output of pumps, motors, and other equipment.

The definition is based on the historical context where one horsepower was originally defined to quantify the power output of horses in relation to mechanical work. In electrical terms, it standardizes power measurements and helps professionals determine the energy requirements for different systems.

Understanding this equivalence is crucial for correctly sizing equipment and ensuring it operates efficiently and effectively for HVAC system designs and service tasks. That way, service technicians and engineers can make informed choices regarding power supply, motor selection, and energy consumption.
