About this calculator

How it works

Bulk modulus describes how strongly a material resists volume change under pressure. A higher value means the material is less compressible.

Formulas

Formulas used

Bulk modulus

K = Delta P / volumetric strain

Worked example

Example calculation

Bulk modulus

K = 2 MPa / 0.001 = 2.00 GPa

Select the units beside each input where a unit menu is shown.
Use the highlighted result for the main property, then review the supporting values for context.

Reference

What the results mean

Bulk modulus

Resistance to uniform compression.

Compressibility

The reciprocal of bulk modulus, useful for fluids and compressible material checks.

Assumptions and limits

Before using the result

Inputs are treated as representative engineering values from a test, datasheet, or early design estimate.
Material properties vary with grade, heat treatment, temperature, strain rate, moisture, manufacturing route, and test method.
Use verified material data, applicable standards, safety factors, and qualified engineering judgement for final design or failure analysis.
