  • 1 cm4 = 10-8 m4 = 104 mm4
  • 1 in4 = 4.16x105 mm4 = 41.6 cm4
  • 1 cm3 = 10-6 m3 = 103 mm3

 

  • I = moment of inertia
  • W = section modulus

The standard method for specifying the dimension of a American Standard Beam is for example W 20 x 86, which is 20 inches deep with a weight of 86 lb/ft.

I-shaped cross-section beams:

  • Britain : Universal Beams (UB) and Universal Columns (UC)
  • Europe : IPE. HE. HL. HD and other sections
  • US : Wide Flange (WF) and H sections
