Bulk Modulus Calculator

Find a material's bulk modulus from pressure and volume change.

Pressure change (Pa)

Original volume

Volume change

Bulk modulus (Pa) 2,000,000,000

Formula: K = ΔP ÷ (ΔV / V)

Step-by-step with your numbers:

1. Values used:

2. Pressure change = 1,000,000 Pa

3. Original volume = 1

4. Volume change = 0.0005

6. Pressure change x Original volume = 1,000,000 x 1 = 1,000,000

7. Bulk modulus = (Pressure change x Original volume) / Volume change = 1,000,000 / 0.0005 = 2,000,000,000Pa

Did we solve your problem today?

Bulk modulus measures a material's resistance to uniform compression.

The math behind it

K = ΔP ÷ (ΔV/V). A high bulk modulus means the material barely compresses.

1 MPa squeezing 0.05% of 1 m³ → K = 2 GPa.

What has a high bulk modulus?

Diamonds and metals; gases have very low bulk moduli.
