Pipe Weight Calculator
Calculate hollow round-pipe metal volume and weight from outside diameter, wall thickness, length, and material density.
Formula
Weight = pi/4 x (OD^2 - ID^2) x length x density.
About the Pipe Weight Calculator
Calculate hollow round-pipe metal volume and weight from outside diameter, wall thickness, length, and material density. This tool keeps the requested measurements separate and applies the named method instead of substituting an unrelated general estimate.
How the Pipe Weight Calculator Works
All dimensions are converted to centimeters so volume in cubic centimeters multiplied by density gives kilograms.
Formula
Weight = pi/4 x (OD^2 - ID^2) x length x density.
The calculation runs in your browser. Values are validated for required ranges, compatible units, and method-specific restrictions before results are displayed.
Required Inputs
- Outside diameter (required) - enter in in.
- Wall thickness (required) - enter in in.
- Pipe length (required) - enter in ft.
- Material density (required) - enter in g/cm3.

Accuracy and Limitations
Nominal pipe sizes, schedules, coatings, tolerances, fittings, and mill specifications can change actual weight.
Keep units consistent, use measurements that represent the actual situation, retain full precision during the calculation, and round only the final answer. Professional decisions may require current official rules, field measurements, laboratory methods, or specialist review.
