How many psi does one foot of water head equal?

One foot of water head is equivalent to approximately 0.433 psi. This relationship arises from the principles of hydrostatics, which describe how the pressure in a fluid increases with depth due to the weight of the fluid above it. In this case, 1 psi equals the pressure exerted by a column of water that is approximately 2.31 feet high. Therefore, when you calculate the pressure exerted by 1 foot of water, you can convert feet to psi by using the conversion factor that approximately 2.31 feet of water equals 1 psi. This leads to the understanding that 1 foot of water head translates to about 0.433 psi, making it a useful reference for various applications in water treatment and management.
