How to Convert BTU (th)/second/sq. foot to Dyne/hour/centimeter

Converting BTU (th)/second/sq. foot (Btu/(s·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 BTU (th)/second/sq. foot translates to 4.085615 × 10⁸ Dyne/hour/centimeter (1 dyn/(h·cm) = 2.447612 × 10⁻⁹ Btu/(s·ft²)).

Direct Factor1 Btu/(s·ft²) = 4.085615 × 10⁸ dyn/(h·cm)

Inverse Ratio1 dyn/(h·cm) = 2.447612 × 10⁻⁹ Btu/(s·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:

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 Btu/(s·ft²) = 11348.93 watt per square meter (W/m²)

2. Target SI Bridge (k_target):1 dyn/(h·cm) = 2.777778 × 10⁻⁵ watt per square meter (W/m²)

Step-by-step substitution for BTU (th)/second/sq. foot → Dyne/hour/centimeter:V(dyn/(h·cm)) = V(Btu/(s·ft²)) × ( 11348.93 / 2.777778 × 10⁻⁵ ) = V(Btu/(s·ft²)) × 4.085615 × 10⁸

Worked Example

Converting 15 Btu/(s·ft²) yields an exact output of 6.128422 × 10⁹ dyn/(h·cm) in Dyne/hour/centimeter. Under higher industrial throughput, 1000 Btu/(s·ft²) translates to 4.085615 × 10¹¹ dyn/(h·cm).
