0.5 Sq Ft is one half of a square foot. A square foot is an area 1 foot long by one foot wide. A square foot can also be described in inches instead, so the area of one square foot is 12 inches long by 12 inches wide, or 144 square inches. 0.5 Sq Ft is half a square foot, and is equal to 144 square inches multiplied by 0.5, or one half. So half a square foot equals 72 square inches. 1 psi is one pound per square inch. If you spread 1 psi over an area of 72 square inches, you divide the pressure quantity by the area quantity: 1 psi divided by 72 square inches = 1/72 psi, or 0.0139psi.
