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

Estimate mass from dimensions and density. Default density is approximately 1,410 kg/mยณ for unfilled acetal copolymer.

Material density

Default 0.05093948 lb/inยณ โ‰ˆ 1,410 kg/mยณ. Use your gradeโ€™s datasheet. Clear the field to restore the default in the selected unit.

Acetal Weight Formulas

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

Acetal Flat Sheet Weight Formula = L * W * T * d

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

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

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

Acetal Square Angle Weight Formula = (2*W*T – T^2) * L * d

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

Acetal C Channel Weight Formula = (2*W*T1+(H-2*T1)*T2)* L * d

Variables used in these equations: 

  • L is the length
  • W is the width (or leg/flange width, depending on shape)
  • H is the height
  • T is the thickness
  • d is the density
  • D is the outer diameter
  • R is the outer radius
  • r is the inner radius
  • T1 is the channel thickness along the width (flange thickness)
  • T2 is the channel thickness along the height (web thickness)

Choose each dimensionโ€™s unit beside its input. The calculator converts dimensions and density automatically and reports mass in pounds or kilograms. The round hollow tube uses diameters in the inputs; the radius formula above is equivalent when R and r are half those diameters.

What is the density of Acetal?

The default density is 0.05093948 lb/in^3 (approximately 1410 kg/mยณ), representative of unfilled acetal copolymer. Use the gradeโ€™s datasheet when available; acetal grades differ.
