That would also depend on the thickness of that square inch!
Solid Aluminum is 165 lb per cubic foot. Therefore, 165 divided by 1728 would be .095 lb per cubic inch.
.032 Aluminum sheet typically weighs about .45lbs per square foot. Do one square inch would be 1/144th of that, or .003lbs. A little under 1/10th of an ounce
You can't say 'pressure per square inch. It's just 'pressure', which equals force per square inch. You divide the person's weight by the area of the foot in contact with the stairs to get the answer.

75 psig For pipe flanges the class rating is the pressure rating for the flange, in pounds per square inch - gauge (psig).
250 PSI WELDED
It depends on the pipe schedule and diameter... For example. Schedule 40 1 Inch pipe has a minimum burst pressure pressure rating of 1440PSI and an operational PSI of 270. Google can provide a complete chart. Just search "PVC Pipes - Pressure Ratings"
It typically takes about 90 pounds per square inch (psi) of pressure to crush an aluminum can. This pressure is exerted evenly on all sides of the can, causing it to collapse.
The PSI rating on a typical radiator cap is usually between 13-16 pounds per square inch (psi). This pressure helps to raise the boiling point of the coolant to prevent overheating. It is important to use the correct psi rating for your vehicle to ensure proper operation of the cooling system.
One cubic inch of 6061 aluminum weighs 0.0975 lb
Aluminum foil comes in a variety of sizes. This includes a roll of 18 inch foil, 12 inch foil, as well as 9 inch foil.

250 psi refers to a unit of pressure measurement, pounds per square inch. When something is described as "welded" it means that it has been joined together using welding techniques. Therefore, 250 psi welded likely refers to a pressure rating for a welded joint or component that can withstand up to 250 pounds per square inch of pressure.
16 gauge
Depends if it is steel or aluminum.
