Coefficient of compressibility
From Glossary of Meteorology
coefficient of compressibility
(Or compressibility.) The relative decrease of the volume of a system with increasing pressure in an isothermal process.
This coefficient is where V is the volume, p the pressure, and T the temperature. The reciprocal of this quantity is the bulk modulus.
