Quickly determine average energies using partition probabilities. Enter values to get accurate results easily every time you calculate them.
| Energy (E) | Probability (p) |
|---|---|
| 1 | 0.2 |
| 2 | 0.3 |
| 3 | 0.5 |
The average value <E> is calculated using the partition function Z:
<E> = Σ(E_i * p_i) / Z , where Z = Σ p_i

Q1: What is the partition function?
It is the sum of all state probabilities, used to normalize probabilities in calculations.
Q2: Can I use negative energies?
Yes, negative energies are valid. Probabilities must remain positive for proper calculation.
Q3: What if Z is zero?
If the partition function is zero, average value calculation is invalid. Check input probabilities.
Q4: How many values can I enter?
You can enter any number of energies and probabilities as long as they match in count.
Q5: Can I download results?
Yes, CSV and PDF download options are available for saving calculated average values.
Q6: Is this calculator responsive?
Yes, layout adjusts for large screens, tablets, and mobile devices using a grid structure.
Q7: Can I reuse inputs?
Yes, form keeps your last inputs so you can modify and recalculate easily.
Q8: Is formula provided?
Yes, the formula used is displayed above along with example data for reference.
