Pipe Weight Calculator
Calculate the weight of a pipe by outer diameter, wall thickness, length, and material. Free online pipe weight calculator.
Weight = Cross-sectional Wall Area × Length × Density
(π/4)(0.1016² − 0.0889²) × 3.048 × 7850 kg/m³
45.46 kg
100.23 lbs
Weight per Foot
4.546 kg/ft
Internal Water
18.92 kg
Filled (Pipe + Water)
64.38 kg
Wall Cross-Sectional Area
0.00190 m²
Pipe Material Volume
0.00579 m³
Internal Water Volume
0.01892 m³
How Does the Pipe Weight Calculator Work?
Enter the outer diameter, wall thickness, length, and material. The calculator finds the inner diameter, computes the cross-sectional area of the pipe wall as (π/4) × (OD² − ID²), multiplies it by the length to get material volume, and then by the material density to get weight. It also reports the weight per foot and the additional weight of water held in the pipe's interior.
Example
For a 10 ft steel pipe with a 4-inch outer diameter and 0.25-inch wall: OD = 0.1016 m, ID = 0.0889 m. Wall area = (π/4)(0.1016² − 0.0889²) = 0.0019 m². Material volume = 0.0019 × 3.048 = 0.0058 m³. At 7850 kg/m³, the pipe weighs about 45.6 kg (100.5 lbs), roughly 4.56 kg per foot. Filled with water, it holds about 18.9 kg more.
Common Use Cases
- Estimating transport and lifting loads for pipe installations.
- Calculating structural load on supports, hangers, and brackets.
- Comparing weight between steel, aluminum, copper, and PVC options.
- Sizing pipe for water-filled service in plumbing and sprinkler systems.
FAQs
What is the difference between carbon steel and steel?
Carbon steel is the most common form of steel used in pipes, with a density very close to 7850 kg/m³ — the same value this calculator uses for both options. Stainless steel is slightly denser at about 8000 kg/m³.
Does this include the weight of fittings and flanges?
No. The calculator estimates the bare pipe body only. Couplings, flanges, elbows, and valves add extra weight and should be accounted for separately in project planning.
Why does the water-filled weight matter?
A buried or supported pipe must carry not only its own weight but also the weight of the liquid inside. The water-filled value gives the realistic load for support and foundation design.
