Calculate sheet, plate, round bar, tube, square bar, angle, and channel weight across steel, stainless steel, aluminum, brass, copper, and titanium.
Metal weight is derived directly from the exact cross-sectional geometric area, continuous stock length, and alloy mass density constant:
Carbon steel is nearly three times denser than aluminum (0.2833 vs 0.0975 lb/in³). Calculating exact piece weights before dispatch prevents exceeding flatbed trailer DOT weight limits and ensures overhead shop cranes are rated for the payload.
Calculating hollow metal tubing by outside dimensions alone yields 200% to 500% over-estimates. Our calculator computes true wall ring cross-sectional area ($\pi (OD - t) t$), accurately determining hollow structural steel (HSS) weight.
CNC machine shops buy raw hexagonal and round bar stock by the pound but machine finished parts by geometric CAD volumes. Accurate alloy density modeling eliminates under-bidding raw billet material costs.
A 16-gauge sheet is not the same across metals (16 ga steel is 0.0598" thick, while 16 ga aluminum is 0.0508"). Entering exact decimal inches ensures true weight calculation without generic table errors.
Pick carbon steel, stainless 304/316, aluminum, brass, or copper.
Select plate, round bar, square bar, hex, tube, or angle iron.
Enter width, thickness, outer diameter, and length in inches or mm.
Specify total piece count and price per pound or kilogram.
Review piece weight, total batch tonnage, and material cost.
