      Relation Between Kilowatt (kW) and Joule per second (J/s)

      Let me explain to you about the relation between Kilowatt kW and Joule per second (J/s) first before moving to the conversion process. Because it’s essential to grasp what these units represent.

      What is Kilowatt (kW)?

      A kilowatt (kW) is a unit of power equal to 1,000 watts. Kilowatt (kW) is a unit of power measurement which is commonly used in Power plant output. Widely used in electricity generation, transmission, and consumption. Equivalent to 1.341 horsepower. Highlights power ratings for appliances, vehicles, and renewable energy sources..

      What is Joule per second (J/s)?

      Kilowatt (kW) is another unit of power measurement that is used in Nutritional needs. Joule per second is a unit of power equal to one watt.. Widely used in electricity generation, transmission, and consumption. Equivalent to 1.341 horsepower. Highlights power ratings for appliances, vehicles, and renewable energy sources..

      How to Convert Joule per second (J/s)?

      The conversion between Kilowatt (kW) and Joule per second (J/s) follows a simple formula:

      Kilowatt = Kilowatt × 1000

      Where, 1000 is the value that allows you to convert between Kilowatt (kW) and Joule per second (J/s).

      So,

      1 Joule per second = 1000 Kilowatt

      And, 1 Kilowatt = 1/1000 Joule per second

      Examples of Converting Kilowatt (kW) to Joule per second (J/s)

      To convert any value from Kilowatt (kW) to Joule per second (J/s), simply multiply the amount of Kilowatt (kW) by the conversion factor:

      1 Joule per second = 1000 Kilowatt

      For example, if you want to convert 5 Kilowatt into Joule per second and the conversion factor is 1000, then:

      5 Kilowatt = 5 x 1000 Joule per second
