Pipe Weight Calculator
Calculate pipe weight per unit length and total weight from outside diameter, wall thickness, length, and material density.

Pipe geometry, material, and total length.
How this calculator works
A pipe's cross-section is an annulus (ring) — outside diameter minus a hollow bore. Weight per unit length is the annular area multiplied by density:
OD is outside diameter, t is wall thickness, ID is the resulting inside diameter, and ρ is material density. Multiply the per-meter weight by total pipe length for the total weight.
Common Schedule 40 steel pipe reference
| Nominal size | OD (mm) | Wall (mm) |
|---|---|---|
| 1" | 33.4 | 3.38 |
| 2" | 60.3 | 3.91 |
| 4" | 114.3 | 6.02 |
Always confirm OD and wall thickness from the actual pipe schedule/spec you're using — these vary by standard (ANSI, DIN, JIS) and schedule number.
Frequently asked questions
Does this work for tube as well as pipe?
Yes — the annular cross-section formula is identical for round tube; just use the tube's actual OD and wall thickness.
What if I only know the inside diameter?
Enter OD as ID + 2t instead — rearrange to whichever two of OD, ID, and t you know, then compute the third before using this calculator.
