Bulk Modulus Calculator

Your details

Choose which quantity you want to calculate; enter the other three.
The original (uncompressed) volume of the sample.
The applied pressure increment. Use a positive number for compression (volume decrease).
The decrease in volume caused by the pressure. Enter as a positive number (compression convention).

Bulk modulus: 213.2 GPa

  • A bulk modulus of 213.2 GPa means the material resists compression strongly compared to water (about 2.15 GPa).
  • The volumetric strain is 0.0469 %, meaning the volume changes by 0.0469 % under this pressure.
  • Compressibility (1/B) is 4.690 TPa-1: how much volume change results from a unit pressure increase.

Next stepCompare your result to the material table below. Values much lower than expected may indicate a porous sample or measurement error.
