Pipe Weight Calculator – Imperial and Metric
Click for Data or Table:
Pipe Weight Formula – This formula can be used to determine the weight per foot for any size of pipe with any wall thickness.
The imperial formula is:
Wt/Ft = 10.69*(OD – Wall Thickness)*Wall Thickness
*Totals should be used as an estimate of weight.
* Totals should be used as an estimate of weight.
How to calculate the weight
The weight of any tube can be calculated with the following formulas. Simply multiply the appropriate alloy density by the calculation shown below of the required part.
