horsepower to watts
How do you convert horsepower to Watts?
To convert mechanical horsepower to Watts, multiply the horsepower value by 745.69987158 (or use 746 for standard electrical motors). For example, a 3 HP pool pump equals 3 × 745.7, which is approximately 2237 Watts (2.237 kW). This is standard for mechanical pumps, industrial ventilation fans, and automotive engine power sheets.
