What does pound-force per square foot measure?

It measures pressure as one pound-force applied uniformly over one square foot of area, used mainly in US customary engineering.

Why convert from pound-force/square foot to psi?

Because psi represents pressure per square inch, it is more suitable for specifications in hydraulics, tires, and equipment requiring precise pressure measurements.

Can this conversion be used for dynamic pressure readings?

This tool is designed for static or steady pressure conditions; dynamic pressures may differ and require specialized methods.
