      Relation Between Watt (W) and Horsepower (hp)

      Let me explain to you about the relation between Watt W and Horsepower (hp) first before moving to the conversion process. Because it’s essential to grasp what these units represent.

      What is Watt (W)?

      A watt (W) is the SI unit of power, defined as one joule per second. Watt (W) is a unit of power measurement which is commonly used in . Named after James Watt, a pioneer in steam engine development. Fundamental to electrical and mechanical power measurements. Highlights the rate of energy conversion or transfer in diverse systems. Widely used in everyday life, from lightbulbs to power plants..

      What is Horsepower (hp)?

      Watt (W) is another unit of power measurement that is used in Energy consumption. Horsepower (hp) is a unit of power originally based on the work a horse can do in one minute.. Named after James Watt, a pioneer in steam engine development. Fundamental to electrical and mechanical power measurements. Highlights the rate of energy conversion or transfer in diverse systems. Widely used in everyday life, from lightbulbs to power plants..

      How to Convert Horsepower (hp)?

      The conversion between Watt (W) and Horsepower (hp) follows a simple formula:

      Watt = Watt × 0.0013410220895950279

      Where, 0.0013410220895950279 is the value that allows you to convert between Watt (W) and Horsepower (hp).

      So,

      1 Horsepower = 0.0013410220895950279 Watt

      And, 1 Watt = 1/0.0013410220895950279 Horsepower
