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 (meter (m)) 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 lea = 4828.032 meter (m)

2. Target SI Bridge (k_target):1 dm = 0.1 meter (m)

Step-by-step substitution for League → Decimeter:V(dm) = V(lea) × ( 4828.032 / 0.1 ) = V(lea) × 48280.32

Mathematical FormulaValue in Decimeter = Value in League × 48280.32Direct computational formula applied for standard conversion.

Worked Example

For an engineering input of 250 lea, applying the conversion factor yields exactly 1.207008 × 10⁷ dm. At larger operational scale, 100 League corresponds to 4828032 dm.

Inverse check: 1 dm = 2.071237 × 10⁻⁵ lea.
