How many feet of head are equivalent to 1 psi?

Explanation:
The concept is that pressure can be expressed as a height of a water column, called head, using the relation P = γ h, where γ is the water’s weight density. For water, γ is about 62.4 pounds-force per cubic foot. Convert 1 psi to pounds-force per square foot: 1 psi = 144 lbf/ft^2. Then the head is h = P/γ = 144 / 62.4 ≈ 2.31 ft. So 1 psi corresponds to roughly 2.31 feet of water head.
