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

Acrylic Weight Formulas

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

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

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

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

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

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

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

Acrylic 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 Acrylic?

The average density of Acrylic is 0.0426302 lbs/in^3.
