  • 1 cm4 = 10-8 m = 104 mm
  • 1 in4 = 4.16x105 mm4 = 41.6 cm4
  • 1 cm3 = 10-6 m = 103 mm

The standard method for specifying the dimensions of a American Wide Flange Beam is for example W 310 x 250 x 79, which is  310 mm deep, 250 mm wide and with a weight of 79 kg/m.

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
