Formulas Used
General: Weight = Volume × Density. Units depend on the selected system.
- Plate / Sheet:
V = (W × T) × L. - Rectangular Bar:
V = (W × H) × L. - Round Bar:
V = (π × D² / 4) × L. - Hex Bar:
Area = 3√3 a² / 2, where a is across flats;V = Area × L. - Pipe / Round Tube:
V = [π(OD² − ID²)/4] × L, withID = OD − 2t. - Rectangular Tube:
V = [B×H − (B−2t)(H−2t)] × L. - Angle (L): Approx.
Area = t × (A + B − t); thenV = Area × L.
Metric: dimensions in mm are converted to meters internally. Imperial: inches are converted to feet. Densities are applied as kg/m³ or lb/ft³ accordingly.

FAQs
Typical handbook values are provided for common alloys. You can override density to match supplier datasheets or heat certificates when necessary.
This tool expects outer diameter and wall thickness. If you only know inner diameter, compute thickness as
(OD − ID)/2.It assumes sharp corners, ignoring fillets and root radii. For precise fabrication estimates, use manufacturer-provided section properties.
Cost equals calculated weight times price per mass unit. Set price per kilogram or per pound depending on the selected unit system.
