To calculate the weight of a bar, use the formula: Weight = Volume × Density. For cylindrical bars: Volume = π × (d/2)² × Length, where d is diameter. Then multiply the volume by the material’s density (e.g., steel ≈ 7.85 g/cm³).
The weight of 1 bar depends on its shape, size, and material. For example, a round steel bar with a 25 mm diameter and 1 meter length weighs approximately 3.85 kg. You can calculate it using the formula: Weight (kg) = (π/4) × d² × L × ρ, where d is diameter, L is length, and ρ is the material density.
To calculate MS (Mild Steel) bar weight, use the standard formula: Weight (kg) = (d² × L) / 162, where d is the diameter in millimeters and L is the length in meters. This formula is commonly used for round MS bars and assumes the density of mild steel is approximately 7,850 kg/m³.
