How to Convert Calorie to Joule and Joule to Calories

  • A Calorie is used to measure the amount of heat. It is represented as kcal or Cal (capital C).
  • A Joule is a unit of energy and is defined as the force on an object to move it by 1 meter with 1 newton force
  • 1 Calorie is same as a kcal.
    1 kcal is equal to 1 Calorie (caps C)
    1 kcal is equal to 1000 calories (small c)
    To convert Calorie to Energy / Joule (kj), multiply given Calorie value by 4.184

  • To convert Energy / Joule to Calorie, divide the given energy value in Kilo Joules by 4.184

Formula for Converting Calories Into Energy (Cal to joule/kcal to kjoules)

kcal to kjoules (kcal to kj)

1 kcal = 4.184 kj

kcal to joules (kcal to j)

1 kcal = 4184 joules

cal to joule ( cal to j)

1 cal = 4184 joules

cal to kjoule (cal to kj)

1 cal = 4.184 kjoules

kjoules to kilo calories (kj to kcal)

1 kj = 0.239 kcal

kjoules to cal ( kj to cal, kj to gram calorie)

1 kj = 239 cal

joule to kcal (J to kcal)

1 j = 0.00239 kcal

joules to calories (J to calories)

1 j = 0.24 kcal

Relation between Calorie and Joule

Conversion Table icon
  • A calorie is a unit of energy that is used to measure the amount of energy that food and drinks contain.
  • A Joule / kilojoule (KJ) is a unit of energy that is used to measure the amount of work that is done or the amount of heat that is produced.
  • One Calorie (kcal) is equal to 4.184 kilojoules.
  • The body converts calories to joules in order to perform various functions, such as metabolism, physical activity, and growth.
  • The efficiency of calorie to energy (joule) conversion can vary depending on a number of factors, such as the type of food consumed, the individual's metabolism, and the level of physical activity.
  • On average, the body is able to convert about 20-25% of the calories consumed into useful energy.
  • To convert Calories(kcal) to kilojoules, you can multiply the number of calories by 4.184.
  • For example, to convert 100 calories to kilojoules, you would do the following:

    100 calories * 4.184 kilojoules/calorie = 418.4 kilojoules

Some interesting facts about Calorie to Joule Conversion

Conversion Table icon
  • The calorie to joule conversionis used in a variety of applications, including:
    • Nutrition: To calculate the energy content of food and drinks.
    • Physics: To calculate the energy required to perform a particular task.
    • Engineering: To design machines and devices that are efficient at using energy.
  • The body's metabolism is responsible for converting calories to joules. Metabolism is the process by which the body breaks down food to release energy.
  • Physical activity also requires energy. The more active you are, the more energy your body will burn.
  • Growth and development also require energy. Children and adolescents need more energy than adults to support their growth and development.
  • The human body burns calories to produce energyfor all of its activities, including breathing, thinking, and moving.
  • The average adult burns about 2,000 calories per day.
  • The energy released from 1 gram of fat is equal to about 9 calories.
  • The energy released from 1 gram of protein is equal to about 4 calories.
  • The energy released from 1 gram of carbohydrates is equal to about 4 calories.
  • A slice of bread contains about 300 joules of energy, while a glass of milk contains about 200 joules of energy.

  • 0.239006 kcal

  • The energy in kilojoules is equal to the kilocalories multiplied by 4.184. one kilocalorie is equal to 4.184 kilojoules. kilojoules = kilocalories × 4.184

  • As per standard definition, it is the amount of energy required to raise the temperature of 1 gram (ml) of water by 1 degree Celsius. This is also called as the 'thermochemical calorie'. 1 calorie = 4.184 Joule. 1 Kilocalorie (C) = 4.184 Kjoule

  • It is the System International Unit (SI) unit of energy and named after Joule. To raise the temperature of 1 g of water by 1 degree celsius needs almost 4000 Joules of energy.

  • It is measured by taking the difference in temperature divided by mass of water.

  • Both are units of energy. The system international unit of energy is Joule. Energy is defined as the ability to do work. The only difference is the value they represent for measuring energy. 1 Calorie (kcal) = 4.184 kilo joules. The Big 'C' in Calorie is same as kilo calorie. 1 kilo calorie (kcal) = 1000 calories. 1 C (capital C) = 1000 calories = 1 kcal.
