Weight Calculation for MS Plate

To calculate the weight of a mild steel (MS) plate, multiply its length, width, and thickness by the standard density of mild steel (7.85 g/cm³). Our calculator handles the math instantly, but knowing the manual formula helps with quick site estimates and material planning.

MS Plate Weight Formula and Manual Calculation

The industry-standard formula for mild steel plate weight is:

Weight (kg) = Length (mm) × Width (mm) × Thickness (mm) × 0.00000785

For imperial units (inches and lbs):

Weight (lbs) = Length (in) × Width (in) × Thickness (in) × 0.283

Where 0.00000785 is the density of mild steel converted to kg/mm³, and 0.283 is the density in lbs/in³.

Step-by-Step Calculation Example

  • Step 1: Measure your plate: Length = 1000 mm, Width = 1000 mm, Thickness = 10 mm
  • Step 2: Apply formula: 1000 × 1000 × 10 × 0.00000785 = 78.5 kg
  • Step 3: Convert to lbs (optional): 78.5 × 2.20462 ≈ 173.06 lbs

This matches exactly what our MS plate weight calculator returns in under a second.
