Pipe Weight Formula
Weight (kg/m) = (OD − WT) × WT × 0.02466
Or: Weight = π/4 × (OD² − ID²) × Density / 1,000,000 ID = OD − 2 × Wall Thickness
2" NB Pipe (60.3mm OD × 3.91mm WT): Weight = (60.3−3.91) × 3.91 × 0.02466 = 5.44 kg/m 6m pipe = 5.44 × 6 = 32.64 kg

Frequently Asked Questions
Weight (kg/m) = (OD − WT) × WT × 0.02466, where OD is outer diameter in mm and WT is wall thickness in mm. This applies to mild steel pipes (density 7850 kg/m³).
ID = OD − (2 × Wall Thickness). For example, 60.3mm OD with 3.91mm wall: ID = 60.3 − 7.82 = 52.48mm.
