Metal weight is calculated by multiplying the volume of the section by the material density. The volume formula depends on the cross-sectional shape: for a round bar it is π/4 × d² × L, for a plate it is L × W × T, and for a pipe it is π/4 × (OD² − ID²) × L.
This calculator supports 14 common engineering metals including mild steel, stainless steel (SS304 & SS316), aluminium, copper, brass, cast iron, titanium, and more. All densities are based on standard reference values at room temperature.
Metal bar weight = cross-sectional area × length × density. For a round bar: π/4 × d² × L × ρ. For mild steel (density 7.85 g/cm³), a 25mm round bar of 6m length weighs approximately 23.12 kg.
Mild steel (MS) has a density of 7.85 g/cm³ or 7,850 kg/m³. This is the standard density used in all steel weight calculations. Stainless steel SS304 is slightly denser at 8.0 g/cm³.
Pipe weight = π/4 × (OD² − ID²) × L × density, where OD is outer diameter, ID is inner diameter (OD − 2 × wall thickness), and L is length. All dimensions in consistent units.
