psi = pounds per square inch There are (12*12) 144 square inches in a square foot, and you are going from the smaller unit to a larger one, so divide.

3000 / 144 = 20.833 pounds per square foot. ■

^^^^other guy... wrong...

you are not converting from smaller to larger, it is PER inch to PER foot.

3000 * 144 = 432000 lb/ft^2
