How much does your pipe weigh?
Enter the outside diameter, wall thickness, length and material — get the weight instantly, both empty and full of water.
Full of water it weighs about 51.1 lb. Inside bore ≈ 2.067 in.
Weight = π · wall · (OD − wall) × material density × length. Enter the pipe's real outside diameter and wall thickness (from its schedule or spec). Densities are typical physical values for each material, not code figures.

Common questions
- How do you calculate the weight of a pipe?
- The pipe wall is a hollow cylinder, so weight per length = π × wall thickness × (outside diameter − wall thickness) × the material's density, then multiply by the length. For steel the folded shortcut is weight (lb/ft) = 10.68 × (OD − wall) × wall with both in inches, or weight (kg/m) = 0.02466 × (OD − wall) × wall with both in mm. Enter your figures above and the calculator does it for any material.
- How much does 2-inch steel pipe weigh per foot?
- A 2-inch nominal Schedule-40 steel pipe (outside diameter 2.375 in, wall 0.154 in) weighs about 3.66 lb/ft (5.44 kg/m). Full of water it comes to roughly 5.1 lb/ft. Weight rises steeply with size and wall thickness, so always use the pipe's real outside diameter and wall, not the nominal name.
- Does the weight include the water inside the pipe?
- The main figure is the empty (dry) pipe — what you lift and hang. The calculator also shows the water-filled weight, which is the empty weight plus the water the bore holds (bore area × 1000 kg/m³). Filled weight matters for supports and hangers on long horizontal runs.
- Do I use the outside or inside diameter?
- Enter the outside diameter and the wall thickness — that is how pipe is specified (a schedule or spec gives OD and wall). The calculator works out the inside bore for you as OD minus twice the wall. Using the nominal size instead of the true outside diameter will give the wrong weight.
