UCS = 0.0123e^(4.89 ´ ^p)

where:

0.0123 is in psi.

4.89 is in g/cc.

Density is in g/cc.

This equation is derived from a synthesis of published data on 74 samples with average density of 2.4 g/cc. The cross plot of UCS versus density shows a wide scattering for densities above 2.4 g/cc. No information about the nature of the samples and test procedures is available.
