How to Calculate Steel Coil Weight
Calculation Formula
Weight (kg) = π × (OD² – ID²) × Width × Density ÷ 4,000,000
Where:
π ≈ 3.1416, OD = Outer Diameter (mm), ID = Inner Diameter (mm)
Width = Coil Width (mm), Density = Material Density (g/cm³)
The constant 4,000,000 comes from unit conversion (mm³ to cm³ to kg)
