What does kcal mean?
kilocalories
Checking calories in food The calorie content is often given in kcals, which is short for kilocalories, and also in kJ, which is short for kilojoules. A kilocalorie is another word for what’s commonly called a calorie, so 1,000 calories will be written as 1,000kcals.
What is Kilojule content?
A kilojoule (or Calorie) is a unit of energy. In Australia, we use kilojoules (kJ) to measure how much energy people get from consuming a food or drink. The kilojoule content of foods depends on the amount of carbohydrates, fats and proteins present in the food, and the portion size.
How do you calculate kcal energy?
The formula is Energy (in Kcal) = 4x (Proteins and carbohydrates mass in grams) + 9 x mass of fat in grams.
How do you convert kcal to kJ?
To convert a kilocalorie measurement to a kilojoule measurement, multiply the energy by the conversion ratio. The energy in kilojoules is equal to the kilocalories multiplied by 4.184.
How do you convert kJ to kcal?
How to convert from kilojoules to kcal
- Kilojoules to international kilocalories. 1 kcalIT = 4.1868 kJ. The energy in international kilocalories E(kcal-IT) is equal to the energy in kilojoules E(kJ) divided by 4.1868:
- Kilojoules to 15°C kilocalories. 1 kcal15 = 4.1855 kJ.
- Kilojoules to 20°C kilocalories. 1 kcal20 = 4.182 kJ.
