Bulk modulus: The ratio of hydrostatic stress to the volumetric strain within the elastic range is called bulk modulus.
\(K=-\frac{dP}{\frac{dV}{V}}\)
SI unit of the bulk modulus is the same as that of pressure i.e., Nm–2 or Pa.
Compressibility: The reciprocal of the Bulk modulus of the material of a body is called the compressibility of that material.
\(compressibility ∝ \frac{1}{Bulk \;Modulus}\)
Unit of compressibility ∝ 1/Unit of Bulk Modulus ∝ 1/Nm–2 ∝ m2N-1 ∝ m2/N
