What Is Embodied Energy?
Energy (energy) is a measure of the range of motion cycles of the basic unit of matter in space. Modern physics has clarified the quantitative relationship between mass and energy, which is Einstein's mass-energy relationship: E = MC² .

- "Energy" has many forms of existence in nature. According to the law of conservation of energy, energy can be transformed from one form to another. For the convenience of calculation, a unified unit for "energy" in various forms of existence, that is, Joule (J) or (Cal). The unit of energy used in nutrition has been using Cal or Kcal for many years. 1Kc refers to the energy required to raise the temperature of 1Kg of pure water from 15 ° C to 16 ° C. The internationally accepted energy unit is Joule (J). 1J refers to the energy required to move a 1Kg object by 1m with a force of 1 Newton (N). 1000KJ = 1 × 10 6 J. The conversion of the two energy units is as follows:
- 1KJ = 1000J, 1000KJ = 1 × 10 6 J
- 1Kc = 4.184KJ, 1KJ = 0.239Kc
- 1000Kc = 4.184MJ, 1MJ = 239Kc
