      Relation Between Calorie (cal) and Joule (J)

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

      What is Calorie (cal)?

      A calorie is the amount of heat energy required to raise the temperature of one gram of pure water by one degree Celsius. Calorie (cal) is a unit of energy measurement which is commonly used in Nutrition, Energy. Calories are commonly used to measure the energy content of food. The term "calorie" is often used interchangeably with "kilocalorie" in the context of food and nutrition..

      What is Joule (J)?

      Calorie (cal) is another unit of energy measurement that is used in Physics, Energy. The joule is the SI unit of energy, defined as the amount of work done when a force of one newton is applied over a distance of one meter. 2 . Calories are commonly used to measure the energy content of food. The term "calorie" is often used interchangeably with "kilocalorie" in the context of food and nutrition..

      How to Convert Joule (J)?

      The conversion between Calorie (cal) and Joule (J) follows a simple formula:

      Calorie = Calorie × 4.1868

      Where, 4.1868 is the value that allows you to convert between Calorie (cal) and Joule (J).

      So,

      1 Joule = 4.1868 Calorie

      And, 1 Calorie = 1/4.1868 Joule

      Examples of Converting Calorie (cal) to Joule (J)

      To convert any value from Calorie (cal) to Joule (J), simply multiply the amount of Calorie (cal) by the conversion factor:

      1 Joule = 4.1868 Calorie

      For example, if you want to convert 5 Calorie into Joule and the conversion factor is 4.1868, then:

      5 Calorie = 5 x 4.1868 Joule
