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 Foot to the fourth (ft⁴)
An imperial second-moment-of-area unit (1 ft⁴ ≈ 0.00863 m⁴) used for large cross-sections: reinforced-concrete beams in US civil engineering, bridge girders, and large composite sections. Less common than in⁴ but shows up when the section size warrants it.
