Pipe Weight Calculator
Estimate steel pipe weight using OD, wall thickness, and length. Supports imperial and metric units for quick takeoff.
Formula Reference
Cross-Section Area
A = π × (OD^2 - ID^2) / 4
Weight
W = A × L × ρ

Basic formula
Weight = Area × Length × Density, where Area = π × (OD^2 - ID^2) / 4 and ID = OD - 2 × wall.
Typical densities
Carbon steel ~ 0.283 lb/in^3 (7850 kg/m^3). Stainless steel is slightly higher (~0.289 lb/in^3).
Unit consistency
Use inches with feet for imperial inputs, or millimeters with meters for metric inputs. Keep units consistent for accuracy.
Frequently Asked Questions
Is this the same as ASME B36.10M weights?
It is a geometric estimate. Published tables may differ slightly due to tolerances.
Can I use this for stainless steel?
Yes. Update the density to match your material grade.
Why does weight change with schedule?
Higher schedule means thicker wall, which increases cross-sectional area and weight.
Does this include coating or lining?
No. Add coating or lining weight separately if required.
