Mathematical Conversion Derivation via Coherent SI Base Unit

Under the International System of Quantities (ISQ), dimensional conversion between non-SI units is rigorously resolved by bridging through the coherent SI base unit (square meter (m²)) without arbitrary rounding:

V_{\text{target}} = V_{\text{source}} \times \left( \frac{k_{\text{source} \to \text{SI}}}{k_{\text{target} \to \text{SI}}} \right)

Universal Dimensional Conversion Law (ISO 80000 / NIST SP 811)

1. Source SI Bridge (k_source):1 sq ch = 404.686267 square meter (m²)

2. Target SI Bridge (k_target):1 nm² = 1 × 10⁻¹⁸ square meter (m²)

Step-by-step substitution for Square Chain → Square Nanometer:V(nm²) = V(sq ch) × ( 404.686267 / 1 × 10⁻¹⁸ ) = V(sq ch) × 4.046863 × 10²⁰

Mathematical FormulaValue in Square Nanometer = Value in Square Chain × 4.04686267 × 10²⁰Direct computational formula applied for standard conversion.

Worked Example

To convert 120 Square Chain (sq ch) to Square Nanometer (nm²): multiply 120 by 4.046863 × 10²⁰ to get 4.856235 × 10²² nm². At an industrial engineering scale, 480 sq ch converts to 1.942494 × 10²³ nm².
