Formula and methodology
Formula: Boltzmann factor = exp(−ΔE/(kBT)), with kB = 1.380649 × 10⁻²³ J/K.
The factor compares the exponential thermal weighting of a state separated by the entered energy difference.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Energy difference — J; minimum -1.0E-15; maximum 1.0E-15
- Absolute temperature — K; minimum 1.0E-6; maximum 100000
Worked example
| Input | Value |
|---|---|
| Energy difference | 1.0E-21 |
| Absolute temperature | 300 |
Boltzmann factor ≈ 0.7855.
Assumptions and limits
- Energy is in joules and temperature is kelvin.
- The factor is relative and is not a normalized probability by itself.
- Degeneracy, partition functions, and quantum statistics are not modeled.
