How do you determine the PSF of a unit?

• A. Figure out the area. Then divide the number of pounds/area, which equals the PSF
• B. Multiply the area by the pounds per area
• C. Add the area to the pounds per square foot
• D. Use a standard value without calculating area

Answer: (A)

PSF, or pounds per square foot, measures how much weight is carried per unit of area. To determine the PSF of a unit, divide its total weight in pounds by the area it covers in square feet. This yields the weight per square foot. For example, if a unit weighs 600 pounds and sits on 12 square feet, the PSF is 600 ÷ 12 = 50 lb/ft². Multiplying area by pounds per area would give total pounds, not PSF. Adding area to pounds per square foot isn’t a meaningful operation, and using a standard value bypasses the actual calculation, which can vary by unit.
