Acrylic Weight Formulas
The following formulas are used to calculate the weight of Acrylic in different shapes.
Acrylic Flat Sheet/Square Bar Weight Formula = L * W * T * d
Acrylic Round Bar Weight Formula = pi * D^2/4 * L * d
Acrylic Square Hollow Tube Weight Formula = [W^2-(W-2T)^2] * L * d
Acrylic Round Hollow Tube Weight Formula = pi * (R^2-r^2) * L * d
Acrylic Square Angle Weight Formula = (2*W*T – T^2) * L * d
Acrylic T bar Weight Formula = (W*T + (H-T)*T) * L * d
Acrylic C Channel Weight Formula = (2*W*T2 + H*T1) * L * d
Variables used in these equations:
- L is the length
- W is the width (or outer width/leg width depending on the shape)
- H is the height (for the C-channel formula above, H is the inner height)
- T is the thickness (for the T-bar formula above, the flange and web are assumed to have the same thickness T)
- d is the density
- D is the outer diameter
- R is the outer radius
- r is the inner radius
- T1 is the thickness along the width (web thickness for the C-channel)
- T2 is the thickness along the height (flange thickness for the C-channel)
The units used in all calculations on the calculator are inches for lengths and lb/in³ 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 lb/ft³.
What is the density of Acrylic?
The average density of Acrylic is 0.0426302 lb/in³.
