Food calorie tables and caloriesare as follows:

Food calorie tables, based on the energy contained in a unit amount (e.g., 100 grams) of food, drawn or listed in a list for easy dietary care reference. Different foods produce different amounts of energy. For patients with chronic diseases such as obesity, diabetes, hypertension, etc., controlling the daily energy intake of the body is a way to alleviate their own pathologies. Therefore, it is necessary to measure the energy content of each food so that patients can calculate or organize the total **** energy content of the food they eat at each meal.

Unit conversions:

Calorie, kilocalorie, macrocalorie, calorie, kilojoule are all units of heat.

A calorie ("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. One kilocalorie is equal to 1,000 calories, or about 4,186 joules. The macrocalorie, equivalent to the engineering unit kilocalorie per kilogram (kcal), is mostly used in nutritional measurements and fitness manuals.

The conversions between them are:

1 calorie = 4.186 joules

1 kcal = 1 macrocalorie = 1,000 calories = 1,000 calories = 4,186 joules = 4.186 kilojoules.
