Convert horsepower hour to Hartree energy
Please provide values below to convert horsepower hour [hp*h] to Hartree energy [Eh], or Convert Hartree energy to horsepower hour.
1 hp*h = 6.1575e+23 Eh. To convert horsepower hour to Hartree energy, multiply the value by 6.1575e+23; to go the other way, divide by it (1 Eh = 1.6240e-24 hp*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 hp*h = 6.1575e+23 Eh
- 1 Eh = 1.6240e-24 hp*h
- 10 hp*h = 6.1575e+24 Eh
- 100 hp*h = 6.1575e+25 Eh
How to Convert Horsepower Hour to Hartree Energy
1 hp*h = 6.15751051861206e+23 Eh

Horsepower Hour
A horsepower hour (hp*h) is a unit of energy representing the amount of energy equivalent to one horsepower of power sustained over one hour of time.
History/Origin
The horsepower hour originated from the traditional unit of horsepower used to quantify engine power, combined with the hour to measure energy consumption or production over time. It has been used primarily in engineering and energy industries to express energy usage or capacity.
Current Use
Today, the horsepower hour is rarely used in practical applications, having been largely replaced by the joule and other SI units. However, it may still be referenced in historical data, legacy systems, or specific industries dealing with older measurement standards within the energy and mechanical sectors.
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.
