      Relation Between Kilojoule (KJ) and Kilocalorie (KCal)

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

      What is Kilojoule (KJ)?

      A kilojoule is a unit of energy equal to 1000 joules. Kilojoule (KJ) is a unit of energy measurement which is commonly used in Physics, Chemistry. Kilojoules are commonly used in many scientific and engineering applications, particularly in fields such as thermodynamics and mechanics..

      What is Kilocalorie (KCal)?

      Kilojoule (KJ) is another unit of energy measurement that is used in Nutrition, Energy. A kilocalorie is equal to 1000 calories.. Kilojoules are commonly used in many scientific and engineering applications, particularly in fields such as thermodynamics and mechanics..

      How to Convert Kilocalorie (KCal)?

      The conversion between Kilojoule (KJ) and Kilocalorie (KCal) follows a simple formula:

      Kilojoule = Kilojoule × 0.2390057

      Where, 0.2390057 is the value that allows you to convert between Kilojoule (KJ) and Kilocalorie (KCal).

      So,

      1 Kilocalorie = 0.2390057 Kilojoule

      And, 1 Kilojoule = 1/0.2390057 Kilocalorie
