How to Convert Calorie (IT)/hour/cm² to Dyne/hour/centimeter

Converting Calorie (IT)/hour/cm² (cal/(h·cm²)) 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 Calorie (IT)/hour/cm² translates to 418680 Dyne/hour/centimeter (1 dyn/(h·cm) = 2.388459 × 10⁻⁶ cal/(h·cm²)).

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 cal/(h·cm²) = 11.63 watt per square meter (W/m²)
2. Target SI Bridge (ktarget):1 dyn/(h·cm) = 2.777778 × 10⁻⁵ watt per square meter (W/m²)
Step-by-step substitution for Calorie (IT)/hour/cm² → Dyne/hour/centimeter:V(dyn/(h·cm)) = V(cal/(h·cm²)) × ( 11.63 / 2.777778 × 10⁻⁵ ) = V(cal/(h·cm²)) × 418680
Mathematical FormulaValue in Dyne/hour/centimeter = Value in Calorie (IT)/hour/cm² × 418680Direct computational formula applied for standard conversion.
Worked Example

To convert 2.5 Calorie (IT)/hour/cm² (cal/(h·cm²)) to Dyne/hour/centimeter (dyn/(h·cm)): multiply 2.5 by 418680 to get 1046700 dyn/(h·cm). At an industrial engineering scale, 240 cal/(h·cm²) converts to 1.004832 × 10⁸ dyn/(h·cm).

Inverse check: 1 dyn/(h·cm) = 2.388459 × 10⁻⁶ cal/(h·cm²).
