Pipe Weight Calculator

Calculate theoretical unit weight (kg/m or kg/ft) and total weight for steel pipes. Covers Carbon Steel and Stainless Steel across all NPS sizes and standard schedules.

 Steel Pipe — Theoretical Weight

ASME B36.10 / B36.19
OD ID WT Qty × Length
Unit Weight
kg / m
Total Weight
kg
Wall Thickness
mm
Formula W (kg/m) = π × (OD − t) × t × ρ / 1,000,000
where t = wall thickness (mm) · ρ = 7,850 kg/m³ (CS) or 8,000 kg/m³ (SS)
