How the formula works
Weight = Volume × Density | Volume = Cross-section Area × Length
- Round Bar = π × (Diameter/2)² × Length × Density
- Square Bar = Width × Width × Length × Density
- Rectangle = Width × Height × Length × Density
- Pipe = π × (OD² − ID²) / 4 × Length × Density
- Density (Mild Steel) = 7,850 kg/m³ (7.85 g/cm³)
- Density (Stainless) = 8,000 kg/m³
- Density (Tool Steel) = 7,700 kg/m³
- Total Cost = Total Weight × Cost per kg
