Carbon Steel Weight Calculator

ASTM A36 carbon steel has a density of 490 lb/ft³ (7850 kg/m³). This is the most common structural steel grade used in construction and manufacturing. Slight variations exist for other carbon steel grades, but A36 is the industry standard.

Multiply length × width × thickness to get volume, then multiply by steel density (490 lb/ft³). Make sure all dimensions are in the same units first. For example, a 1 ft × 1 ft × 1 inch plate = 0.0833 ft³ × 490 lb/ft³ = 40.8 pounds.

Steel sheet is typically less than 3/16 inch (4.76mm) thick, while plate is thicker than 3/16 inch. Sheets are used for lighter applications like automotive panels, while plates are used for structural components and heavy machinery.

It depends on thickness. A 1/8 inch thick sheet weighs about 163 lbs, while 1/4 inch weighs 327 lbs, and 1/2 inch weighs 653 lbs. The 4×8 size (32 square feet) is standard and easy to transport on most trucks.

No, stainless steel has a slightly different density (501 lb/ft³ for 304 grade) compared to carbon steel (490 lb/ft³). The weight difference is about 2%, so this calculator would be close but not exact for stainless steel applications.
