Frequently Asked Questions

How do you calculate metal weight? +
Metal weight is calculated using the formula: Weight = Volume × Density. For plates: Weight = Length × Width × Thickness × Density. For round bars: Weight = π × (Diameter/2)² × Length × Density. For pipes: Weight = π × (Outer Diameter - Wall Thickness) × Wall Thickness × Length × Density.
What is the formula for MS plate weight calculation? +
MS (Mild Steel) plate weight formula: Weight (kg) = Length (mm) × Width (mm) × Thickness (mm) × 0.00000785. For example, a 1000mm × 1000mm × 10mm MS plate weighs: 1000 × 1000 × 10 × 0.00000785 = 78.5 kg.
What is the density of mild steel? +
The density of mild steel (MS) is approximately 7.85 g/cm³ or 7850 kg/m³. This value is used as the standard for calculating weights of MS plates, pipes, bars, and other structural steel components.
How accurate are online weight calculators? +
Online weight calculators provide theoretical weights based on standard densities and formulas. Actual weights may vary by ±2-5% due to manufacturing tolerances, material composition variations, and measurement accuracy.
