Both kilojoules and kilocalories are units for calculating heat, and 1 kilocalorie is equivalent to the heat used to raise 1kg water 1℃ at a standard atmospheric pressure. 1 kJ =0.2389 kcal, which is converted by this formula, for example, 800 kJ =800×0.2389= 19 1 kcal.
The conversion relationship between kilojoules and calories is 1 kcal =4. 184 kilojoules, 1 kilojoules =0.239 kcal, so that the conversion between kilojoules and kcal can be carried out effectively. The kilojoule is an international unit of heat, which generally refers to 1000 joules. It is often used to measure the calories contained in food and the calories consumed per unit time of a certain exercise.
Brief introduction of focal unit and conversion relationship
Joule (short for coke, symbol J) is the international unit of energy and work. 1 Joule energy is equal to the work done by the point of action of 1 Newton force moving 1 meter distance in the direction of force. The symbol J is named in memory of the British physicist James Prescott Joule. 1 coke = 1 nm, which is also equal to 1 work done by power of watt in 1 sec, 1 coke = 1 watt/sec.
Joule's formula: j =1n m. Joule (short for coke, symbol J) is the international unit of energy and work. 1 Joule energy is equal to the work done by the point of action of 1 Newton force moving 1 meter distance in the direction of force.
