Convert watt-hour to Hartree energy
Please provide values below to convert watt-hour [W*h] to Hartree energy [Eh], or Convert Hartree energy to watt-hour.
1 W*h = 8.2574e+20 Eh. To convert watt-hour to Hartree energy, multiply the value by 8.2574e+20; to go the other way, divide by it (1 Eh = 1.2110e-21 W*h). Both units measure energy and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 W*h = 8.2574e+20 Eh
- 1 Eh = 1.2110e-21 W*h
- 10 W*h = 8.2574e+21 Eh
- 100 W*h = 8.2574e+22 Eh
How to Convert Watt-Hour to Hartree Energy
1 W*h = 8.25735761528613e+20 Eh
Example: convert 15 W*h to Eh:
15 W*h = 15 × 8.25735761528613e+20 Eh = 1.23860364229292e+22 Eh

Watt-Hour
A watt-hour (W·h) is a unit of energy equal to the amount of energy transferred or used when one watt of power is sustained for one hour.
History/Origin
The watt-hour was established as a practical unit of energy measurement with the adoption of the International System of Units (SI) and has been used in electrical and energy industries to quantify energy consumption and storage since the 20th century.
Current Use
Watt-hours are commonly used to measure electrical energy consumption in household appliances, batteries, and energy storage systems, providing a convenient unit for billing, capacity ratings, and energy management.
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.
