How many watts are equivalent to one horsepower (hp)?

• A. 500 watts
• B. 1000 watts
• C. 746 watts
• D. 1200 watts

Answer: (C)

One horsepower (hp) is defined as being equivalent to approximately 746 watts. This conversion is based on the standard used in mechanical and electrical engineering, where horsepower measures the power of engines or motors. Knowing that 1 hp equals 746 watts is essential, especially in contexts where energy consumption, power generation, and motor specifications are discussed. This value is derived from historical calculations made by the engineer James Watt in the 18th century, who sought to understand the power exerted by horses in pulling coal from mines. Though various definitions of horsepower exist for different contexts (like metric horsepower or boiler horsepower), the common and standardized conversion in electrical contexts is 746 watts. Understanding this conversion is crucial for utility marketing representatives, as it allows them to communicate effectively about motorized systems, energy efficiency, and the costs associated with energy consumption in practical applications.
