Convert Hartree energy to therm
Please provide values below to convert Hartree energy [Eh] to therm [thm], or Convert therm to Hartree energy.
1 Eh = 4.1322e-26 thm. To convert Hartree energy to therm, multiply the value by 4.1322e-26; to go the other way, divide by it (1 thm = 2.4200e+25 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 = 4.1322e-26 thm
- 1 thm = 2.4200e+25 Eh
- 10 Eh = 4.1322e-25 thm
- 100 Eh = 4.1322e-24 thm
How to Convert Hartree Energy to Therm
1 Eh = 4.13224340698503e-26 thm
Example: convert 15 Eh to thm:
15 Eh = 15 × 4.13224340698503e-26 thm = 6.19836511047755e-25 thm

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.
Therm
A therm is a unit of energy used primarily to measure natural gas consumption, equivalent to 100,000 British thermal units (BTUs).
History/Origin
The therm was introduced in the early 20th century by the American Gas Association to standardize natural gas billing and measurement; it became widely adopted in North America for energy calculations.
Current Use
Today, the therm is still used in the natural gas industry for billing and energy measurement, although other units like gigajoules and cubic meters are also common globally.
