MS Plate Weight Calculator in kg/lbs/ Sheet Weight Calculator

Calculate the exact weight of Mild Steel (MS) plates and sheets instantly with our free online calculator. Simply enter your dimensions in mm or inches, and get accurate results in both kg and lbs.

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.
