Pipe Weight Calculator
Pounds per foot and total weight for any standard pipe size. Supports Schedule 10, 40, 80, 160, XS, and XXS in carbon steel, stainless, copper, and PVC.
How pipe weight is calculated
Pipe weight per unit length comes from the cross-sectional area of the pipe wall multiplied by the density of the material. For an outside diameter OD and wall thickness t:
Where ID = OD − 2t and ρ is density in lb/in³. The × 12 converts cubic inches per foot of pipe into the per-foot weight. For carbon steel this simplifies to the practical field formula:
That constant bakes in the carbon-steel density of 0.2836 lb/in³ along with the geometric factors. Stainless steel (304/316) is about 1.9% heavier — you can multiply the carbon-steel result by 1.019 for a quick conversion, which is what this calculator does internally.
Material densities used
- Carbon steel (A53, A106): 0.2836 lb/in³ (490.0 lb/ft³)
- Stainless 304 / 316: 0.289 lb/in³ (499.4 lb/ft³)
- Copper (Type K, L, M): 0.323 lb/in³ (558.0 lb/ft³)
- PVC (Sch 40 / 80): 0.0506 lb/in³ (87.4 lb/ft³)
Worked example: 6" SCH 40 carbon steel
NPS 6" pipe has an outside diameter of 6.625" and a Schedule 40 wall of 0.280". Plugging into the simplified formula:
For a 40-foot stick that's about 759 pounds — useful to know before you ask three guys to walk it across a deck plate.
