How to Convert CHU/hour/square foot to Dyne/hour/centimeter

Converting CHU/hour/square foot (CHU/(h·ft²)) to Dyne/hour/centimeter (dyn/(h·cm)) 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 CHU/hour/square foot translates to 204417.693487 Dyne/hour/centimeter (1 dyn/(h·cm) = 4.891944 × 10⁻⁶ CHU/(h·ft²)).

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)

2. Target SI Bridge (ktarget):1 dyn/(h·cm) = 2.777778 × 10⁻⁵ watt per square meter (W/m²)
Step-by-step substitution for CHU/hour/square foot → Dyne/hour/centimeter:V(dyn/(h·cm)) = V(CHU/(h·ft²)) × ( 5.678269 / 2.777778 × 10⁻⁵ ) = V(CHU/(h·ft²)) × 204417.693487
