Frequently asked questions
How do you calculate the weight of carbon steel plate and sheet?
Multiply the cross-section area in square inches by the length in inches and by the density, 0.2836 lb per cubic inch for carbon steel (1018 / A36). For this shape the area is: weight per square foot = 144 x thickness x density. A foot of stock is 12 inches, so weight per foot is area x 12 x 0.2836.
How does carbon steel compare with steel by weight?
Carbon steel is the baseline at 0.2836 lb per cubic inch. Stainless is about 2% heavier, brass about 8% heavier, copper about 14% heavier, and aluminum about 66% lighter for the same size.
