# Delta g Calculator (Gibbs Free Energy)

The Delta g Calculator helps you calculate the Gibbs free energy very easily.

Enter the temperature (T), and changes in enthalpy (ΔH) and entropy (ΔS) to determine the Gibbs free energy.

In case you don’t know, Gibbs free energy, symbolized as G, is the product of enthalpy and entropy.

The free energy change (G) is equal to the enthalpy change plus the product of the temperature and entropy change.

ΔG° = ΔH° – TΔS°
