Understanding Horsepower and Kilowatt
Horsepower (hp)
The horsepower is a unit of power in the Imperial system, used for mechanical measurements.
• 1 horsepower = 745.7 watts
• Originally based on work capacity of draft horses
• Common for internal combustion engines (US/UK)
• Used in automotive, marine, and industrial engines
Kilowatt (kW)
The kilowatt is a unit of power in the SI system, used for metric measurements.
• Standard for household electricity consumption
• Used for electric vehicle charging stations
• Common for industrial motors and pumps
• International standard for power generation
