Weight of MS plate = Length × Width × Thickness × Density
Use all dimensions in meters for the result in kilograms
Density of mild steel = 7850 kg/m³
Formula in kg = L × W × T × 7850
If dimensions are in mm, use:
Weight in kg = (L × W × T × 7850) ÷ 1,000,000,000
If thickness is in mm and length and width are in meters, use:
Weight in kg = L × W × T × 7.85
For square plate:
Weight in kg = Side × Side × Thickness × 7850
For rectangular plate:
Weight in kg = Length × Width × Thickness × 7850
For circular plate:
Weight in kg = π × (Diameter ÷ 2)² × Thickness × 7850
