Discover the effortless way to convert Hartree Energy (E_h) to Kilogram-force Centimeters (kgf·cm) with our precise tool, engineered by Newtum. Get curious about the simplicity of unit conversion!
The Hartree, symbolized as E_h, is a unit of energy named after the British physicist Douglas Hartree. It is used in atomic physics to express the energies of electrons in atoms. One Hartree is equivalent to the energy change when an electron moves across an electric potential of one atomic unit of charge within a vacuum. It is approximately 4.359744650×10^(-18) joules. The Hartree is a fundamental quantity in the atomic system of units, making it integral for quantum chemistry and physics.
Definition of kilogram-force centimeterA kilogram-force centimeter (kgf·cm) is a unit of torque. It represents the rotational force generated by a one kilogram-force acting at the end of a lever one centimeter long. Torque is a measure of the tendency of a force to rotate an object about an axis, fulcrum, or pivot. Just as a linear force is measured in newtons in the International System of Units (SI), torque can be measured in newton-centimeters (N·cm); however, the kgf·cm is still used in some contexts for its intuitive grasp for practical applications.

| 2 E_h | 4.3894 kgf·cm |
| 3 E_h | 6.5841 kgf·cm |
| 4 E_h | 8.7788 kgf·cm |
| 5 E_h | 10.9735 kgf·cm |
| 6 E_h | 13.1682 kgf·cm |
| 7 E_h | 15.3629 kgf·cm |
| 8 E_h | 17.5576 kgf·cm |
| 9 E_h | 19.7523 kgf·cm |
| 10 E_h | 21.9470 kgf·cm |
1 E_h = 2.1947 kgf·cm
1 kgf·cm = 0.4555 E_h
Example 1:
Convert 2 E_h to kgf·cm:
2 E_h = 2 × 2.1947 kgf·cm = 4.3894 kgf·cm
Example 2:
Convert 0.5 E_h to kgf·cm:
0.5 E_h = 0.5 × 2.1947 kgf·cm = 1.09735 kgf·cm
A brief history of the Hartree Energy to Kilogram-force Centimeter conversion begins with the development of the Hartree as a natural unit of energy in quantum chemistry. It was important for simplifying equations involving the hydrogen atom. The kgf·cm, a traditional unit of torque, has been used in engineering and physics. The converter bridges these two units, aiding scientists and engineers in cross-disciplinary work and applications.
