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 (watt per square meter (W/m²)) without arbitrary rounding:

Vtarget=Vsource×(ksource→SIktarget→SI)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 (ksource):1 kW/m² = 1000 watt per square meter (W/m²)
2. Target SI Bridge (ktarget):1 Ly/min = 697.800185 watt per square meter (W/m²)
Step-by-step substitution for Kilowatt/square meter → Langley/minute:V(Ly/min) = V(kW/m²) × ( 1000 / 697.800185 ) = V(kW/m²) × 1.433075
Mathematical FormulaValue in Langley/minute = Value in Kilowatt/square meter × 1.433075Direct computational formula applied for standard conversion.
Worked Example

For an engineering input of 75 kW/m², applying the conversion factor yields exactly 107.480625 Ly/min. At larger operational scale, 1000 Kilowatt/square meter corresponds to 1433.075 Ly/min.

Inverse check: 1 Ly/min = 0.6978 kW/m².
