Select the shape of the LDPE and enter the required variables. The calculator will evaluate and display the LDPE weight.
LDPE Weight Formulas
The following formulas are used to calculate the weight of LDPE in different shapes.
LDPE Flat Sheet Weight Formula = L * W * H * d
LDPE Round Bar Weight Formula = pi * D^2/4 * L * d
LDPE Square Hollow Tube Weight Formula = [W^2-(W-T)^2] * L * d
LDPE Round Hollow Tube Weight Formula = pi * (R^2-r^2) * L * d
LDPE Square Angle Weight Formula = [W^2-(W-T)^2]/2 * L * d
LDPE T bar Weight Formula = (W*T – (H-T)*T)* L * d
LDPE 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 LDPE?
The average density of LDPE is 0.03323711 lbs/in^3.
