- 1 cm4 = 104 mm4 = 10-8 m4 = 0.024 in4
- 1 cm3 = 103 mm3 = 10-6 m3 = 0.061 in3
- 1 cm2 = 102 mm2 = 10-4 m2 = 0.16 in2
- 1 kg/m = 0.67 lb/ft
Example - Converting Moment of Inertia from cm4 to mm4
The Ix Moment of Inertia of beam W 12 x 12 x 230 is 100510 cm4. It can be converted to mm4 by multiplying with 104 as
(100510 cm4) (104 mm4/cm4) = 1005100000 mm4
= 1005 106 mm4
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
