      Relation Between Kilowatt-hour (kwh) and Kilojoule (KJ)

      Let me explain to you about the relation between Kilowatt-hour kwh and Kilojoule (KJ) first before moving to the conversion process. Because it’s essential to grasp what these units represent.

      What is Kilowatt-hour (kwh)?

      A Kilowatt-hour is a unit of energy equivalent to the energy consumed or produced when a power of one kilowatt (kW) is sustained for a duration of one hour. Kilowatt-hour (kwh) is a unit of energy measurement which is commonly used in Electric billing, energy generation. It is a non-SI unit, although widely accepted and used commercially, especially for electrical energy (the SI unit of energy is the Joule, where 1 kWh = 3.6 megajoules). This unit specifically measures the total amount of energy transferred or used, distinct from the kilowatt which measures the rate of energy transfer .

      What is Kilojoule (KJ)?

      Kilowatt-hour (kwh) is another unit of energy measurement that is used in Physics, Chemistry. A kilojoule is a unit of energy equal to 1000 joules.. It is a non-SI unit, although widely accepted and used commercially, especially for electrical energy (the SI unit of energy is the Joule, where 1 kWh = 3.6 megajoules). This unit specifically measures the total amount of energy transferred or used, distinct from the kilowatt which measures the rate of energy transfer .

      How to Convert Kilojoule (KJ)?

      The conversion between Kilowatt-hour (kwh) and Kilojoule (KJ) follows a simple formula:

      Kilowatt-hour = Kilowatt-hour × 3600

      Where, 3600 is the value that allows you to convert between Kilowatt-hour (kwh) and Kilojoule (KJ).

      So,

      1 Kilojoule = 3600 Kilowatt-hour

      And, 1 Kilowatt-hour = 1/3600 Kilojoule

      Examples of Converting Kilowatt-hour (kwh) to Kilojoule (KJ)

      To convert any value from Kilowatt-hour (kwh) to Kilojoule (KJ), simply multiply the amount of Kilowatt-hour (kwh) by the conversion factor:

      1 Kilojoule = 3600 Kilowatt-hour

      For example, if you want to convert 5 Kilowatt-hour into Kilojoule and the conversion factor is 3600, then:

      5 Kilowatt-hour = 5 x 3600 Kilojoule
