This online chemistry calculator is based on the Gay Lussac's Law, which states that the change in pressure of an ideal gas is proportional to the change in temperature of the system when both the mass and the volume remain constant. Thus the product of the volume and temperature of a gas is constant at constant pressure and mass.
