A kilocalorie (kcal), commonly referred to in the context of food energy, is a unit of energy defined as the amount of heat needed to raise the temperature of one kilogram of water by one degree Celsius at one atmosphere of pressure. It is equivalent to 1,000 calories, where the calorie is historically defined as the amount of energy needed to raise the temperature of one gram of water by one degree Celsius.
Definition of HartreeThe Hartree, also known as the atomic unit of energy, is a physical constant named after the physicist Douglas Hartree. It is used primarily in quantum chemistry and atomic physics. One Hartree represents the potential energy between two hydrogen atoms in their ground state and is equivalent to twice the binding energy of an electron in a hydrogen atom. The Hartree is a large unit of energy when compared to everyday scales, and its value is approximately 4.3597447222071 x 10^-18 joules.

| 40 kcal_th | 1.04527808e+25 E_h |
| 50 kcal_th | 1.3065976e+25 E_h |
1 kcal_th = 2.6131952e+23 E_h
1 E_h = 3.827e-24 kcal_th
Example 1:
Convert 3 kcal_th to E_h:
3 kcal_th = 3 × 2.6131952e+23 E_h = 7.8395856e+23 E_h
Example 2:
Convert 5.5 kcal_th to E_h:
5.5 kcal_th = 5.5 × 2.6131952e+23 E_h = 1.43715736e+24 E_h
Initially, the conversion from kilocalories to Hartrees was a niche requirement, largely confined to the fields of physics and chemistry. However, as computational chemistry evolved, the need for precise energy unit conversions became crucial. Scientists developed the Kilocalorie th to Hartree Energy Converter to bridge the gap between macroscopic thermal energy measurements and quantum mechanical energy scales, facilitating better understanding and comparison of energy-related data across disciplines.
Uncover how the Kilocalorie th to Hartree Energy Converter enables various industries to achieve precise energy conversions for practical applications.
Example 1:
Convert 2 kcal_th to E_h:
