How do you convert psi to feet of head?

Explanation:
The key idea is that pressure can be expressed as a height of a water column. At standard conditions, 1 psi corresponds to a column of water about 2.31 feet high. So to convert from psi to feet of head, multiply the pressure by 2.31. In other words, feet of head = psi × 2.31. The other options don’t reflect this direct relationship: 2.31 ft/psi is the correct factor, while the others either use the wrong factor, the inverse, or add a value that doesn’t represent a height.
