Pipe Weight Calculator – Imperial and Metric

## 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

### Pipe Weight - Imperial

Outer Diameter (inches)
Wall Thickness (inches)
Total Length of Pipes (feet)

*Totals should be used as an estimate of weight.

### Pipe Weight - Metric

Outer Diameter (mm)
Wall Thickness (mm)
Total Length of Pipes (meter)

* 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.

Imperial Example
density (lbs/in³) 0.284 lbs/in³
x
(OD² - (OD - 2xT)²) (3.0 in² - (3.0 in - 2x0.022 in)²)

π/4
=
weight 0.702  lbs

Metric Example
density (g/cm³) 7.85g/cm³
x
(OD² - (OD - 2xT)²) (50.0 mm² - (50.0 mm - 2x1.0 mm)²)
