Discover the ease of converting Hartree Energy to nutritional Calories with our Hartree Energy to Calorie nutritional Converter. Developed by Newtum, this tool is a must-try for quick and accurate conversions that pique your scientific curiosity.
Hartree energy, symbolized as Eh, is a physical constant that represents the unit of energy in atomic physics. It's named after the British physicist Douglas Hartree and is equivalent to the energy of an electron in the ground state of a hydrogen atom. This unit is part of the atomic units system and is used extensively in quantum chemistry and physics to simplify calculations involving atomic-scale energies.
Definition of CalorieThe Calorie, with a capital 'C', often referred to as the food calorie, is a unit of energy commonly used in nutritional contexts. It is equivalent to 1000 small calories or one kilocalorie (kcal), the standard unit of energy to express the energy value of foods. One Calorie is the amount of energy needed to raise the temperature of one kilogram of water by one degree Celsius at a pressure of one atmosphere.
| Hartree Energy (Eh) | Calories (cal) |
|---|---|
| 1 Eh | 627.509 kcal |
| 0.1 Eh | 62.7509 kcal |
| 0.01 Eh | 6.27509 kcal |
| 0.001 Eh | 0.627509 kcal |
| 0.0001 Eh | 0.0627509 kcal |
| 1e-5 Eh | 0.00627509 kcal |
| 1e-6 Eh | 0.000627509 kcal |
| 1e-7 Eh | 0.0000627509 kcal |
| 1e-8 Eh | 0.00000627509 kcal |
| 1e-9 Eh | 0.000000627509 kcal |
1 Eh = 627.509 kcal
1 kcal = 1.59388e-3 Eh
Example 1:
convert 2 Eh to kcal:
2 Eh = 2 × 627.509 kcal = 1255.018 kcal
Example 2:
convert 0.5 Eh to kcal:
0.5 Eh = 0.5 × 627.509 kcal = 313.7545 kcal
The Hartree Energy to Calorie nutritional Converter has its roots in the field of quantum chemistry, where energy measurements are often required in atomic units. This converter allows for the translation of the theoretical energy values of particles, expressed in Hartrees, into more tangible units of energy, such as Calories, commonly used in nutrition.
Our Hartree Energy to Calorie nutritional Converter serves as a bridge connecting the realms of quantum physics and nutrition, showcasing real-world applications.
Example 1:
Convert 0.2 Eh to Calories:
0.2 Eh = 0.2 × 627.509 kcal = 125.5018 kcal
Example 2:
Convert 0.05 Eh to Calories:
0.05 Eh = 0.05 × 627.509 kcal = 31.37545 kcal
Hartree Energy (Eh) is a unit of energy in the atomic units system, commonly used in quantum chemistry.
Enter the value in Hartrees into the converter, and it will display the equivalent value in nutritional Calories.
