1070 kilojoules (kJ)=255.623 kilocalories (kcal)
Kilojoule is a unit of heat, joule (abbreviated as kJ, not to be confused with kg, which is kg) is a unit of heat and work in international units, and kilojoule refers to 1,000 joules. Nowadays, kilojoules are often used to measure the calories contained in food and the calories consumed in a certain exercise unit time. People generally control their weight by controlling the calories consumed in food and the calories consumed in exercise.
A kilocalorie (qiān kǎ m) is also called a calorie. A unit of heat equal to 1000 cal (calories), that is, the heat required for 1 kg water temperature increase 1℃ (symbol kcal). Card is the abbreviation of Calorie, which is transliterated from English Calorie (abbreviated as cal). It is defined as the heat required to raise 1 g water at 1 atmospheric pressure. Calorie is a unit of energy, which is still widely used in nutrition measurement and fitness manuals. The international standard unit of energy is Joule.
Extended data:
1, the human body needs heat
The daily calories needed by adults = the basic calories needed for basic metabolism of human body+the calories needed for physical activity+the calories needed for digesting food.
Calories required for digesting food = 10% x (minimum calories required for basic metabolism of human body+calories required for physical activity).
The daily calorie requirement of adults = 1. 1 x (the minimum basic calorie required by basic metabolism of human body+the calorie required by physical activity).
Male: 9250-10090kJ.
Female: 7980-8820 kilojoules
Note: the daily calories provided by food should be no less than 5000-7500 kilojoules, which is the least energy to maintain normal life activities of human body.
A simple algorithm for the basic calorie of human body's basic metabolism
Woman: Basic calories (calories) = weight (kg) x 9
Male: Basic calories (calories) = weight (kg) x 10.

18- 30 years old 14.6 x body weight (kg)+450
3 1- 60 years old 8.6 x weight (kg)+830
Over 60 years old 10.4 x body weight (kg)+600

18- 30 years old 15.2 x body weight (kg)+680
3 1- 60 years old 1 1.5 x body weight (kg)+830
Over 60 years old 13.4 x body weight (kg)+490
2. Metabolism
Generally speaking, adults need at least 1500 kcal of energy every day to maintain body function, because even if you lie still, your body still needs energy to maintain body temperature, cardiopulmonary function and brain operation. Basal metabolic consumption will be different due to the differences of individual height, weight, age and gender.
Human beings need energy to survive and get it from food. The calorie content in food is a measure of how much potential energy the food produces. 1 g carbohydrate contains 4,000 calories, 1 g protein contains 4,000 calories, and 1 g fat contains 9,000 calories. Food is generally composed of these three substances. Therefore, as long as we know the contents of these three substances in food, we can know how many calories or how much energy food contains.
Our body "burns" calories in food through metabolism, which decomposes carbohydrates into glucose and other sugars through enzymes, fats into glycerol and fatty acids, and protein into amino acids.
Then, these molecules are transported to cells through the blood stream, where they can be immediately absorbed and utilized, or they can enter the final metabolic stage to react with oxygen and release their stored energy.
