📊 Steel Breakdown

Parameter Value Unit

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
