Horsepower (hp)
Horsepower is a unit of power commonly used in the United States and other countries that still follow the imperial system. It measures the power needed to lift 550 pounds by one foot in one second. There are two common types of horsepower: mechanical horsepower (hp) and metric horsepower (PS or Pferdestärke). One mechanical horsepower is approximately equal to 746 watts, and one metric horsepower is about 735.5 watts.
Kilowatt (kW)
Kilowatt is the standard unit of power in the International System of Units (SI). It measures power in the metric system and is widely used globally. One kilowatt is equal to 1,000 watts. Kilowatts are commonly used to measure the power output or consumption of electrical devices, appliances, and industrial machinery.
How to convert hp to kW
To convert horsepower (hp) to kilowatts (kW), you can use the following conversion formulas:
Mechanical Horsepower (hp) to Kilowatts (kW):
kW = hp × 0.7355
Horsepower (hp) to Kilowatts (kW):
P(kW) = 0.745699872 ⋅ P(hp)
For Example – Convert 10 hp to kW
Ans. P(kW) = 0.745699872 ⋅ 10hp = 7.45699872 kW
