Entropy Calculator
Calculate statistical entropy using Boltzmann's equation ($S = k_B \ln W$)
Boltzmann's Formula: $S = k_B \ln W$
Where $k_B$ is the Boltzmann constant ($1.3806 \times 10^{-23}\text{ J/K}$) and $W$ is the number of accessible microstates.
Where $k_B$ is the Boltzmann constant ($1.3806 \times 10^{-23}\text{ J/K}$) and $W$ is the number of accessible microstates.

Calculation Results
⚠️ Boltzmann's entropy formula relates microscopic states (probability) to macroscopic thermodynamic entropy. This calculation represents statistical entropy per system configuration; molar entropy values in chemistry tables are typically scaled per mole using the gas constant ($R = N_A k_B$).
