Uses a pure-copper density of 8,960 kg/mยณ (8.96 g/cmยณ). Dimensions are nominal; actual alloy composition, tolerances, hollow-section geometry, coatings, insulation, fittings, and manufacturing variation can change measured weight.

Copper Weight Formulas

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

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

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

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

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

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

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

Copper C Channel Weight Formula = (2*W*T+Hin*T)* L * d

Variables used in these equations: 

  • L is the length
  • W is the width
  • H is the height
  • Hin is the inner height (for the C channel)
  • d is the density
  • D is the diameter
  • T is the thickness
  • R is the outer radius
  • r is the inner radius

The calculator converts all entered lengths to inches internally and uses a copper density of lbs/in^3. If you do the calculations manually in other units, use consistent units throughout (for example, if lengths are in feet, use density in lb/ft^3).

What is the density of Copper?

The average density of Copper is 0.323700536 lbs/in^3.
