How to Convert Calorie (th)/minute/cm² to Erg/hour/square millimeter

Converting Calorie (th)/minute/cm² (cal (th)/(min·cm²)) to Erg/hour/square millimeter (erg/(h·mm²)) 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 (th)/minute/cm² translates to 2.5104 × 10⁷ Erg/hour/square millimeter (1 erg/(h·mm²) = 3.983429 × 10⁻⁸ cal (th)/(min·cm²)).

Direct Factor1 cal (th)/(min·cm²) = 2.5104 × 10⁷ erg/(h·mm²)

Inverse Ratio1 erg/(h·mm²) = 3.983429 × 10⁻⁸ cal (th)/(min·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:

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 cal (th)/(min·cm²) = 697.333333 watt per square meter (W/m²)

2. Target SI Bridge (k_target):1 erg/(h·mm²) = 2.777778 × 10⁻⁵ watt per square meter (W/m²)

Step-by-step substitution for Calorie (th)/minute/cm² → Erg/hour/square millimeter:

V(erg/(h·mm²)) = V(cal (th)/(min·cm²)) × ( 697.333333 / 2.777778 × 10⁻⁵ ) = V(cal (th)/(min·cm²)) × 2.5104 × 10⁷

Mathematical FormulaValue in Erg/hour/square millimeter = Value in Calorie (th)/minute/cm² × 2.5104 × 10⁷Direct computational formula applied for standard conversion.

Worked Example

For an engineering input of 15 cal (th)/(min·cm²), applying the conversion factor yields exactly 3.7656 × 10⁸ erg/(h·mm²). At larger operational scale, 5000 Calorie (th)/minute/cm² corresponds to 1.2552 × 10¹¹ erg/(h·mm²).

Inverse check: 1 erg/(h·mm²) = 3.983429 × 10⁻⁸ cal (th)/(min·cm²).
