About Millimeter to the fourth (mm⁴)
A metric second-moment-of-area unit equal to 10⁻¹² m⁴. Used for small-section analysis in mechanical engineering — shaft bending, spring-wire strength, and small-fastener cross-sections. Fastener-specification handbooks and shaft-calculation tools often work in mm⁴ to avoid scientific notation for typical values.
About Inch to the fourth (in⁴)
An imperial second-moment-of-area unit dominant in US structural engineering. AISC Steel Construction Manual lists Ix, Iy, J, and Cw for every rolled shape in in⁴. A W14×90 wide-flange beam has Ix ≈ 999 in⁴. Essential for US structural design using LRFD or ASD methods.
