Select the shape of the Polypropylene and enter the required variables. The calculator will evaluate and display the Polypropylene weight.

## Polypropylene Weight Formulas

The following formulas are used to calculate the weight of Polypropylene in different shapes.

Polypropylene Flat Sheet Weight Formula = L * W * H * d

Polypropylene Round Bar Weight Formula = pi * D^2/4 * L * d

Polypropylene Square Hollow Tube Weight Formula = [W^2-(W-T)^2] * L * d

Polypropylene Round Hollow Tube Weight Formula = pi * (R^2-r^2) * L * d

Polypropylene Square Angle Weight Formula = [W^2-(W-T)^2]/2 * L * d

Polypropylene T bar Weight Formula = (W*T – (H-T)*T)* L * d

Polypropylene C Channel Weight Formula = (2*W*T1+H*T2)* L * d

Variables used in these equations:

- L is the length
- W is the width
- H is the height
- d is the density
- D is the outer diameter
- T is the thickness
- R is the outer radius
- r is the inner radius
- T1 is the channel thickness along the width
- T2 is the channel thickness along the height

The units used in all calculations on the calculator are inches for lengths and lbs/in^3 for density. These can be switched for any equivalent unit as long as the density units are also changed to match. For example, if you change the lengths to feet, the density should be in lbs/ft^3 or mass/ft^3.

## What is the density of Polypropylene?

The average density of Polypropylene is 0.032695199 lbs/in^3.
