      Relation Between Calorie (cal) and Megajoule (MJ)

      Let me explain to you about the relation between Calorie cal and Megajoule (MJ) 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 Megajoule (MJ)?

      Calorie (cal) is another unit of energy measurement that is used in Industry, Large-Scale Energy. A megajoule is a unit of energy equal to one million joules.. 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 Megajoule (MJ)?

      The conversion between Calorie (cal) and Megajoule (MJ) follows a simple formula:

      Calorie = Calorie × 0.0000041868

      Where, 0.0000041868 is the value that allows you to convert between Calorie (cal) and Megajoule (MJ).

      So,

      1 Megajoule = 0.0000041868 Calorie

      And, 1 Calorie = 1/0.0000041868 Megajoule
