Why Calculate Metal Weight?
Calculating the weight of metal is essential for shipping estimates, structural engineering, CNC job quoting, and material purchasing. The weight depends on the shape of the piece, its dimensions, and the density of the specific alloy used.
How to Calculate Metal Weight
Metal Weight Formula
Volume formulas by shape:
- Plate/Sheet: V = Length × Width × Thickness
- Round bar: V = π × (Diameter/2)² × Length
- Tube: V = π × ((OD/2)² − (ID/2)²) × Length
Common Metal Densities
Aluminum: 2,700 kg/m³ (168.6 lb/ft³). Titanium: 4,507 kg/m³. Steel (carbon): 7,850 kg/m³ (490 lb/ft³). Stainless steel: 8,000 kg/m³. Brass: 8,500 kg/m³. Copper: 8,960 kg/m³. Lead: 11,340 kg/m³. Aluminum is about 3 times lighter than steel, making it popular for aerospace and automotive applications where weight savings matter.
