Steel Pipe Weight Calculator
Theoretical weight of steel pipe / tube: <code>W = (OD − t) × t × 0.02466</code> kg/m (OD and t both in mm).

Pipe
W = (OD − t) × t × 0.02466 kg/m (mm), derived from π · (OD − t) · t · ρ.- Theoretical weights are based on a steel density of 7850 kg/m³ and differ from actual weighed weights because of rolling tolerances.
- Structural sections (I-beams, channels, angles) have complex cross-sections: use the section tables rather than these simplified formulas.
