Calories, kilocalories, calories and kilojoules are all units of heat. Calories (calories for short) are defined as the heat required to raise 1 gram of water 1 degree Celsius at 1 atmospheric pressure. 1 kcal is equal to 1000 kcal, which is about 4 186 joules. Calories, equivalent to kilocalories per kilogram of engineering units, are mostly used for nutrition measurement and fitness manuals.

The transformation between them is:

1 card =4. 186 joules

1 kcal = 1 kcal = 1000 kcal = 1000 calories =4 186 joules =4. 186 kj.

The calories a normal person needs every day are related to his weight. The relationship between daily calorie intake and body weight ratio is about 1 kcal/hour, which is 4. 186 kcal/hour. So the daily calories of an adult weighing 50 kilograms are as follows:

Heat required = 4. 186 kJ * 24 hours * 50 kg = 5023.2 kJ.

On average, for every kilogram of weight gain, the calories required by human body will increase by 0. 1MJ. Generally speaking, an adult man needs about 9.25 to10900 joules every day; An adult woman needs about 7.98 to 8.82 million joules a day. Pupils need about 9.25 million joules of heat every day on average, which is similar to the minimum heat required by an adult man. Middle school students are developing and need to consume more calories. Boys need 10.465 MJ on average every day, while girls need 10.046 MJ.

The daily calorie requirement is related to body weight. To calculate your basic heat more accurately, you can use the following formula:
