Convert Hartree energy to horsepower (metric) hour
Please provide values below to convert Hartree energy [Eh] to horsepower (metric) hour [hp*h], or Convert horsepower (metric) hour to Hartree energy.
1 Eh = 1.6466e-24 hp*h. To convert Hartree energy to horsepower (metric) hour, multiply the value by 1.6466e-24; to go the other way, divide by it (1 hp*h = 6.0733e+23 Eh). Both units measure energy and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 Eh = 1.6466e-24 hp*h
- 1 hp*h = 6.0733e+23 Eh
- 10 Eh = 1.6466e-23 hp*h
- 100 Eh = 1.6466e-22 hp*h
How to Convert Hartree Energy to Horsepower (Metric) Hour
1 Eh = 1.64655774964494e-24 hp*h
Example: convert 15 Eh to hp*h:
15 Eh = 15 × 1.64655774964494e-24 hp*h = 2.46983662446741e-23 hp*h

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.
Horsepower (Metric) Hour
A unit of energy representing the amount of work done by one horsepower over one hour, equivalent to 745.7 joules.
History/Origin
The horsepower hour was historically used to quantify energy in mechanical and engineering contexts, especially in the era of steam and early engines, but has largely been replaced by standard energy units like joules and kilowatt-hours.
Current Use
It is rarely used in modern practice, but may still appear in legacy systems or specific industrial applications to measure energy output or consumption related to horsepower-rated equipment.
Frequently Asked Questions
What is 1 Hartree energy in horsepower (metric) hour?
1 Hartree energy (Eh) = 1.6466e-24 horsepower (metric) hour (hp*h).
How do you convert Hartree energy to horsepower (metric) hour?
Multiply the Hartree energy value by 1.6466e-24. For example, 25 Eh × 1.6466e-24 = 4.1164e-23 hp*h.
