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section-property catalogs, Eurocode 3 (EN 1993) structural-steel design tables, BS 5950 (UK steel design code, now superseded by Eurocode but still in legacy use), DIN 1025 (German wide-flange and channel steel-shape standards), CEN EN 10025 European hot-rolled steel section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 Inch to the fourth (in⁴)
An imperial second-moment-of-area unit (≈ 4.162 × 10⁻⁷ m⁴ per NIST SP 811 = 41.62 cm⁴). The in⁴ is the universal working unit in US structural engineering: the AISC Steel Construction Manual (15th edition) lists Ix, Iy, J, and Cw for every rolled W-shape, S-shape, HSS hollow structural section, channel, angle, and tee in in⁴; the ASCE 7-22 loading code, AISC 360-22 steel design code, ACI 318-25 reinforced-concrete code, AWC NDS 2024 wood structural design specification, and all US-edition structural-engineering textbooks (Salmon-Johnson, McCormac, Vinnakota) use in⁴ throughout for cross-section bending properties. Reference values from AISC Manual Table 1-1: W14×90 wide-flange Ix = 999 in⁴, Iy = 362 in⁴; W30×173 (a common heavy-bay beam) Ix = 6,260 in⁴; HSS 8×8×½ Ix = Iy = 75.1 in⁴; L4×4×½ angle Ix = Iy = 7.67 in⁴. Essential for US LRFD (Load and Resistance Factor Design) and ASD (Allowable Strength Design) calculations. Convert in⁴ to m⁴ by multiplying by 4.162 × 10⁻⁷; to cm⁴ by multiplying by 41.62.
