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

Stainless Steel Weight Formulas

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

Stainless Steel Flat = L * W * H * d

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

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

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

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

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

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

Stainless 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.

What is the density of Stainless Steel?


The average density of Stainless Steel is 0.2886571 lbs/in^3.
