In thermodynamics, Enthalpy is measured as the sum of internal energy and the product of volume and pressure. It is a state function that has the dimension same as that of energy that is joule in S.I and ergs in c.g.s. Its value depends on the pressure, composition, and temperature of the system.

The equation to calculate enthalpy is: H = E +P V

Where H = enthalpy of the system

E represents internal energy

P represents the pressure and

V is volume.
