HDPE Weight Formulas
The following formulas are used to calculate the weight of HDPE in different shapes.
HDPE Flat Sheet Weight Formula = L * W * H * d
HDPE Round Bar Weight Formula = pi * D^2/4 * L * d
HDPE Square Hollow Tube Weight Formula = [W^2-(W-T)^2] * L * d
HDPE Round Hollow Tube Weight Formula = pi * (R^2-r^2) * L * d
HDPE Square Angle Weight Formula = [W^2-(W-T)^2]/2 * L * d
HDPE T bar Weight Formula = (W*T – (H-T)*T)* L * d
HDPE 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 HDPE?
The average density of HDPE is .0415 lbs/in^3.
