If you know what the time to stop is, you can divide it into the momentum and come up with the average force. However, psi = F/A, and the area of the bullet footprint on the plate will be continuously increasing due to deformation, so all in all there's really only a VERY ill-defined relationship.....

the bullet is propelled by an explosion of gunpowder which can be best expressed in psi (about 20,000 for a high powered rifle). When the bullet strikes the target it has a momentum and delivers energy which can be measured and described with momentum.
Basicall- psi starts the bullets flight and the ending can be measured with momentum. There is a science known as ballistics with deals extensively with this information and everything in between.

No relevant relationship whatsoever.
Ultimately the size of the bullet will limit psi upon impact, but armor piercing bullets will go through that steel plate.
