Convert kilowatt-second to Hartree energy
Please provide values below to convert kilowatt-second [kW*s] to Hartree energy [Eh], or Convert Hartree energy to kilowatt-second.
1 kW*s = 2.2937e+20 Eh. To convert kilowatt-second to Hartree energy, multiply the value by 2.2937e+20; to go the other way, divide by it (1 Eh = 4.3597e-21 kW*s). Both units measure energy and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 kW*s = 2.2937e+20 Eh
- 1 Eh = 4.3597e-21 kW*s
- 10 kW*s = 2.2937e+21 Eh
- 100 kW*s = 2.2937e+22 Eh
How to Convert Kilowatt-Second to Hartree Energy
1 kW*s = 2.29371044869059e+20 Eh
Example: convert 15 kW*s to Eh:
15 kW*s = 15 × 2.29371044869059e+20 Eh = 3.44056567303589e+21 Eh

Kilowatt-Second
A kilowatt-second (kW·s) is a unit of energy equal to the energy transferred or converted when a power of one kilowatt is applied for one second.
History/Origin
The kilowatt-second has been used historically in physics and engineering to quantify energy, especially in contexts where power and time are relevant, but it is less common than other energy units like joules or kilowatt-hours.
Current Use
Today, the kilowatt-second is primarily used in specialized fields such as electrical engineering and energy calculations, often for convenience in measuring short-term energy transfer, but it is largely replaced by the joule in most applications.
Hartree Energy
The Hartree energy (Eh) is a unit of energy used in atomic physics, representing the total energy of an electron in a hydrogen atom in its ground state.
History/Origin
Named after the American physicist Douglas Hartree, the Hartree energy was introduced in the early 20th century as a fundamental atomic unit of energy within the system of atomic units, facilitating calculations in quantum mechanics.
Current Use
The Hartree energy is primarily used in theoretical and computational chemistry and physics to express energies at the atomic and molecular scale, especially in quantum chemistry calculations and atomic physics research.
