About this enthalpy unit converter
Convert enthalpy units for reaction heat, phase-change data, thermochemical tables, HVAC analysis, and molecular energy comparisons.
The eV per particle option uses Avogadro-scale conversion so molar thermodynamic values can be compared with atomic-scale energies.
Units covered
Enthalpy units
J/mol, kJ/mol, cal/mol, kcal/mol, BTU/mol, and eV per particle.
Chemistry ready
Useful for heats of reaction, formation enthalpy, vaporization, fusion, and bond energy references.
Mole to particle
Bridges molar thermodynamics and atomic or molecular energy scales.
How to use it
- Enter the enthalpy value from your table or calculation.
- Select the current unit and target unit.
- Use eV per particle for molecular or solid-state energy comparisons.
