FAQ

What is the Bulk Modulus?

The Bulk Modulus is defined as the ratio of the infinitesimal pressure increase to the resulting relative decrease of the volume. Bulk Modulus is usually measured using the Pascal for Pressure. Note that the value of Bulk Modulus is always positive.

Can the Bulk Modulus be negative?

No, the Bulk Modulus, measured in Pressure cannot be negative.

What unit is used to measure Bulk Modulus?

Bulk Modulus is usually measured using the Pascal[Pa] for Pressure. Kilopascal[Pa], Bar[Pa], Pound Per Square Inch[Pa] are the few other units in which Bulk Modulus can be measured.
