How to Convert Dyne/hour/centimeter to Btu (th)/second/square foot

Converting Dyne/hour/centimeter (dyn/(h·cm)) to Btu (th)/second/square foot (Btu (th)/(s·ft²)) is a core calculation in Heat Flux Density, which measures the rate of thermal energy transfer radiating or conducting through a unit area per second. This calculation bridges modern MKSA metric standards with the historical Gaussian centimetre-gram-second (CGS) electrostatic and electromagnetic framework. In CGS systems, electromagnetic units (such as statvolts, abvolts, dynes, ergs, and gauss) are formulated directly from mechanical dimensions, with electrostatic-to-electromagnetic relations tied to the speed of light in vacuum (c ≈ 2.99792458 × 1010 cm/s). Exactly 1 Dyne/hour/centimeter translates to 2.447612 × 10⁻⁹ Btu (th)/second/square foot (1 Btu (th)/(s·ft²) = 4.085615 × 10⁸ dyn/(h·cm)).

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 dyn/(h·cm) = 2.777778 × 10⁻⁵ watt per square meter (W/m²)
2. Target SI Bridge (ktarget):1 Btu (th)/(s·ft²) = 11348.931795 watt per square meter (W/m²)
Step-by-step substitution for Dyne/hour/centimeter → Btu (th)/second/square foot:V(Btu (th)/(s·ft²)) = V(dyn/(h·cm)) × ( 2.777778 × 10⁻⁵ / 11348.931795 ) = V(dyn/(h·cm)) × 2.447612 × 10⁻⁹
