kcal means "kilocalorie". "Cal" means calories.

1. Calorie is a unit of energy and is still widely used in nutritional measurement and fitness manuals. The international standard unit of energy is the joule.

One calorie of energy or heat can raise the temperature of 1 gram of water by 1 degree Celsius. 1 calorie is equal to 4.184 joules (joules are a commonly used unit of energy in physics). 1 kcal = 1 kcal = 1000 calories.

We often say that "a bowl of rice contains about 200 calories." In fact, the calories listed on food or food packages are often referred to as calories, which are also recorded with a capital letter C. So the "about 200 calories" here is not actually 200 calories, but refers to 200 calories (Calorie).

This is because people confuse "c" and "C" in daily life. Usually, the number of calories is simply the number of calories. For example, when you jog for 2 kilometers on a treadmill and burn 100 calories, it means 100,000 calories), that is, your consumption should actually be said to be 100 calories.

2. In English, "calorie" (the first letter is lowercase) means calories, and small calories are also recorded as cal. 1cal is approximately equal to 4.184 joules. "Calorie" (the first letter is capitalized) means large calories. , 1Cal is approximately equal to 4184 Joules.

Extended information

1. Calorie (abbreviated as "calorie") is defined as the amount of heat required to raise 1 gram of water by 1 degree Celsius at 1 atmosphere of pressure. Calories, kilocalories, kcals, calories, and kilojoules are all units of heat. The conversion between them is:

1 calorie = 1 calorie = 4.184 joules.

1 kcal = 1 kcal = 1000 calories = 1000 calories = 4184 joules = 4.184 kilojoules.

2. The calories of fat are about 900 calories per 100 grams; the calories of sugar and protein are only 400 calories per 100 grams.

For example, the drink at hand costs 180KJ per 100ML, which is approximately equal to 43 kcal/kcal per 100ML.

A bottle of 600ML is 258 kcal/kcal.
