The calorie of a boiled egg is 80 calories.

1 kcal =4. 186 kcal

So the calorie of an egg is: 80x4.186 = 334.88kj.

However, the calorie of an fried egg is: 120 calories x4. 186=502.32 kilojoules.

Extended data:

The calories a normal person needs every day are related to his weight. The relationship between calorie intake per hour and body weight is about 1 kcal/hour/kg, that is, 4. 186 kj/hour/kg. Therefore, the normal average daily calories required by an adult weighing 50 kg are as follows:

Average required heat = 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 million joules per day, while girls need 10.046 million joules per day.
