Quick answer

How this pipe & tube weight calculator works

Pipe and tube weight equals hollow cross-sectional area multiplied by length and material density. Select a standard steel pipe, PVC pipe, electrical conduit, or copper water-tube size, or enter dimensions for round, square, and rectangular tubing.

How to use the calculator

  1. 1Choose Circular for pipe, conduit, copper water tube, or round tubing; choose Rectangular for square or rectangular tubing.
  2. 2Select a standard size preset or enter outside dimensions, wall thickness, cut length, and quantity.
  3. 3Choose the matching material density or enter a custom density from the manufacturer or supplier.
  4. 4Read total weight and review volume, surface area, nominal-size assumptions, and units before using the estimate.

Worked example

2-inch Schedule 40 steel pipe

Inputs
One 10 ft length with a 2.375 in outside diameter, 0.154 in wall, and steel density of 0.2836 lb/in³.
Result
Estimated pipe weight = 36.6 lb.

The nominal 2-inch size is converted to its actual outside diameter and wall before the hollow-cylinder volume is multiplied by steel density.

Common questions

What to know before using the result

Is nominal pipe size the same as outside diameter?
Usually not. Nominal pipe and conduit trade sizes are names. A standard preset loads the corresponding actual outside diameter and wall thickness.
Which pipe and conduit families are included?
The catalog includes Schedule 40 and 80 steel pipe, Schedule 40 and 80 PVC pipe, EMT, IMC, RMC, and Type K, L, and M copper water tube.
Can I calculate square or rectangular tube weight?
Yes. Under Tube, choose Rectangular and enter width, height, wall, length, and outside corner radius. Fabworks stock sizes are available with Fabworks materials.
Does the result include fittings or coatings?
No. Add fittings, couplings, coatings, weld seams, and manufacturing tolerances separately when they materially affect assembly weight.

Formula

m = A × L × ρ

The selected flat or tube geometry gives volume. Rectangular tube includes rounded outside and concentric inside corners. Mass is volume multiplied by density.

Assumptions and limits

  • Dimension-based estimates assume uniform thickness and nominal dimensions.
  • Rectangular tube uses the entered outside radius and a concentric inside radius equal to outside radius minus wall thickness.
  • Standard pipe, conduit, and copper-tube presets use nominal dimensions and representative material densities.
  • Tube estimates exclude fittings, couplings, coatings, weld seams, and manufacturing tolerances.
  • Surface area includes outer, inner, edge, and open-end faces where applicable.
  • Published density values are representative; verify alloy certificates when tolerances matter.
Educational estimate
Use this result for learning and early design exploration. Verify safety-critical or production decisions with the governing standard, material data, real tooling, and a qualified engineer.
