Formulas Used:
Round: ((π × D²) / 4) × L × Q × ρ
Rectangular: W × H × D × Q × ρ
ρ = Material density in kg/mm³
Important Note
These calculations provide theoretical weight values based on standard material densities. Actual weights may vary slightly depending on material grade, manufacturing tolerances, and surface treatments. Always verify with your material supplier for precise specifications.
Material Density Reference
Common material densities for weight calculations
| Material | Density (kg/m³) | Density (kg/mm³) | Common Applications |
|---|---|---|---|
| Steel (Mild) | 7850 | 0.00000785 | General construction, machining |
| Stainless Steel | 7900-8000 | 0.0000079-0.0000080 | Corrosion resistant applications |
| Aluminium | 2700 | 0.0000027 | Lightweight structures, aerospace |
| Brass | 8500 | 0.0000085 | Decorative, electrical components |
| Copper | 8960 | 0.0000896 | Electrical, thermal applications |
| Bronze | 8700 | 0.0000087 | Bearings, marine applications |
| Titanium | 4500 | 0.0000045 | High strength, aerospace, medical |
Calculation Tips:
- Units: All dimensions should be entered in millimeters (mm) for accurate results
- Density: Values shown are for standard grades - alloys may have different densities
- Tolerance: Add 2-5% for material waste and machining allowances
- Pricing: Update the price per kg based on current market rates and your supplier quotes
- Verification: Always verify critical calculations with your material supplier
