Polycarbonate Weight Formulas

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

Polycarbonate Flat Sheet/Square Bar Weight Formula = L * W * T * d

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

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

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

Polycarbonate Square Angle Weight Formula = (2*W*T - T^2) * L * d

Polycarbonate T bar Weight Formula = (W*T + (H-T)*T)* L * d

Polycarbonate C Channel Weight Formula = (2*W*T1+Hi*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
  • Hi is the channel inner height

The calculator uses inches for all length inputs and returns weight in pounds (lb). Density can be entered in lb/in³ or kg/m³; kg/m³ is converted internally to lb/in³.
