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

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 calories, about 4 186 joules.

Calories, equivalent to kilocalories per kilogram of engineering units, are mostly used for nutrition measurement and fitness manuals.

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 1kcal/hr, that is, 4.186kj/hr/hr. Therefore, the daily calories of adults weighing 50kg are as follows:

Heat required = 4.186kj * 24 * 50 = 5.023mj.

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 to 10.09 mj of heat every day; An adult woman needs about 7.98 to 8.82 megajoules of heat every day. Pupils need about 9.25 megajoules of calories every day on average, which is similar to the minimum calorie required by an adult man. Middle school students are developing and need to consume more calories. On average, boys need 10.465 MJ and girls need10.046mj.resources/baike.so.com/doc/5668291-5880955.html "target =" _ blank "title =" 360ency.
