Extended data food calorimeter is to measure the energy contained in each food according to the energy contained in the unit quantity (such as 100g), so as to calculate or arrange the total energy contained in the food eaten in each meal. The list thus obtained or listed is convenient for reference of diet and health care.
Unit conversion: Calories, kilocalories, kilocalories, calories and kilojoules are all thermal units.
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.
