About Centimeter to the fourth (cm⁴)
A metric second-moment-of-area unit equal to exactly 10⁻⁸ m⁴. cm⁴ is the dominant practical working unit in European structural-steel section-property catalogs, Eurocode 3 (EN 1993) structural-steel design tables, BS 5950 (UK steel design code, now superseded by Eurocode but still in legacy use), DIN 1025 (German wide-flange and channel steel-shape standards), CEN EN 10025 European hot-rolled steel section properties, and BlueScope / British Steel / ArcelorMittal section catalogs. Every European structural engineer working in steel uses cm⁴ daily for beam Iy / Iz (strong-axis and weak-axis second moments of area), J (St-Venant torsion constant), and Iw (warping constant). Reference values: a European IPE 200 wide-flange beam has Iy = 1,943 cm⁴, Iz = 142 cm⁴; HEB 200 has Iy = 5,696 cm⁴; a 100 × 100 × 6 mm SHS (square hollow section) ~286 cm⁴. Convert cm⁴ to m⁴ by dividing by 10⁸; to in⁴ by dividing by 41.62; to mm⁴ by multiplying by 10⁴.
About Foot to the fourth (ft⁴)
An imperial second-moment-of-area unit equal to ≈ 8.631 × 10⁻³ m⁴ per NIST SP 811 (= exactly 12⁴ = 20,736 in⁴, since 1 ft = 12 in and fourth-power scaling). ft⁴ appears for very-large-cross-section US structural-engineering applications where in⁴ would produce inconveniently large 5-6-digit numbers: reinforced-concrete bridge girders and piers (modern composite-girder bridges with section depths of 6-12 ft), large industrial-tower base flanges, US Bureau of Reclamation hydropower-dam concrete-section analysis, US Army Corps of Engineers lock-and-dam structural elements, and pre-stressed-concrete box-girder bridges. Less common than in⁴ in everyday US structural engineering but shows up consistently when the cross-section size warrants it (e.g., AASHTO LRFD Bridge Design Specifications occasionally use ft⁴ for very-large prestressed-concrete box-girder section properties). Convert ft⁴ to m⁴ by multiplying by 8.631 × 10⁻³; to in⁴ by multiplying by 20,736.
