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section-property catalogs, Eurocode 3 (EN 1993) structural-steel design tables, BS 5950 (UK steel design code, now superseded by Eurocode but still in legacy use), DIN 1025 (German wide-flange and channel steel-shape standards), CEN EN 10025 European hot-rolled steel section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.

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.

It belongs to the metric measurement system.

Centimeters to the fourth are commonly used in structural beam design, column analysis, and mechanical engineering.

Understanding Inches to the fourth

The Inch to the fourth (symbol: in⁴) is a unit of area moment of inertia. 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.
