Weight (kg) = Length (m) × Width (m) × Thickness (mm) × 7.85. For example, a 1m × 1m × 10mm plate weighs 1 × 1 × 10 × 7.85 = 78.5 kg.
Standard MS plate sheets in India typically come in sizes like 2440mm × 1220mm (8ft × 4ft) or 6000mm × 1500mm, with thickness ranging from 1mm to 100mm depending on application.
