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

Carbon Steel Weight Formulas

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

Carbon Steel Flat Sheet Weight Formula = L * W * H * d

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

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

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

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

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

Carbon Steel 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.
