What is the weight of 25 mm MS rod having length of one meter?

The weight of a 25 mm mild steel (MS) rod can be calculated using the formula: weight (kg) = volume (m³) × density (kg/m³). The volume of the rod is given by the formula for the volume of a cylinder: V = π × (radius)² × height. For a 25 mm diameter rod, the radius is 12.5 mm (0.0125 m). The density of mild steel is approximately 7850 kg/m³. Therefore, the weight of a 1-meter long 25 mm MS rod is approximately 2.45 kg.
