Weight is found from density times volume. For a sheet, volume equals thickness times area. Convert the area to square inches: 2 ft^2 is 288 in^2. Use the thickness for 22-gauge stainless, which is about 0.032 inches. The volume is 288 × 0.032 = 9.216 cubic inches. Stainless steel density is about 0.284 lb per cubic inch, so the weight is 9.216 × 0.284 ≈ 2.62 pounds. Therefore, 2 square feet of 22‑gauge stainless steel weighs about 2.62 pounds.
