Need to estimate how heavy a pipe is before ordering, lifting, shipping, or installing it? Use the calculator below to quickly compute total pipe weight and linear weight (weight per meter or per foot) for common materials.
What is pipe weight and why does it matter?
Pipe weight is the mass of a hollow cylindrical section, based on its outside diameter, wall thickness, length, and material density. Knowing this value helps with practical decisions: selecting supports, planning rigging, checking transport limits, pricing material, and reducing safety risks during handling.
Pipe weight formula
A pipe is a hollow cylinder. The formula is based on the volume of material in that cylinder multiplied by density.
- OD = outer diameter
- ID = inner diameter = OD − 2 × wall thickness
- Length = total pipe length
- Density = material density (steel, aluminum, PVC, etc.)
How this calculator works
1) Pick your unit system
Choose Metric or Imperial first. The calculator automatically updates labels and material density values for your selected system.
2) Enter pipe dimensions
Input outer diameter, wall thickness, and total length. The tool calculates inner diameter and cross-sectional metal area automatically.
3) Select material (or custom density)
Use the preset materials for quick results. If your alloy or plastic has a different density, switch to Custom Density and enter your exact value.
4) Read total and linear weight
The output includes total weight in kg and lb, plus linear mass (kg/m and lb/ft), which is useful for estimating load on supports and structures.
Typical material density values
- Carbon Steel: ~7850 kg/m³ (0.2836 lb/in³)
- Stainless Steel: ~8000 kg/m³ (0.2890 lb/in³)
- Aluminum: ~2700 kg/m³ (0.0975 lb/in³)
- Copper: ~8960 kg/m³ (0.3230 lb/in³)
- PVC: ~1400 kg/m³ (0.0506 lb/in³)
Real-world values vary by grade, temperature, and manufacturing standard. For engineering-critical jobs, use certified material data.
Common mistakes to avoid
- Using nominal pipe size as if it were actual outside diameter.
- Mixing units (e.g., mm with feet) without conversion.
- Forgetting that wall thickness must be less than half of OD.
- Ignoring coating, lining, insulation, or fluid fill weight when required.
FAQ
Is this calculator for pipe or solid rod?
This tool is for hollow pipe. For a solid rod, use the solid cylinder formula and remove the inner diameter term.
Can I calculate stainless pipe weight per meter?
Yes. Select Stainless Steel, enter dimensions in metric mode, and the result includes kg/m automatically.
Does schedule affect weight?
Yes. Schedule changes wall thickness, and wall thickness directly changes inner diameter, material volume, and weight.
Final note
This pipe weight calculator is perfect for quick planning and estimation. For final structural or lifting decisions, confirm dimensions and density from project specs, standards, and manufacturer documentation.
