How to Convert Watt/meter/degree Celsius to Kilocalorie (th)/hour/meter/°C

Converting Watt/meter/degree Celsius (W/(m·°C)) to Kilocalorie (th)/hour/meter/°C (kcal (th)/(h·m·°C)) is a core calculation in Thermal Conductivity, which measures a material's intrinsic capacity to conduct and transfer heat through microscopic collisions. Because Kilocalorie (th)/hour/meter/°C is a broader physical scale than Watt/meter/degree Celsius, converting from W/(m·°C) to kcal (th)/(h·m·°C) condenses the numerical figure. It takes 1.162222 Watt/meter/degree Celsius to equal a single Kilocalorie (th)/hour/meter/°C (1 W/(m·°C) = 0.860421 kcal (th)/(h·m·°C)). To convert any quantity, multiply by 0.860421 (or divide by 1.162222).

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 meter kelvin (W/(m·K))) 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 W/(m·°C) = 1 watt per meter kelvin (W/(m·K))
2. Target SI Bridge (ktarget):1 kcal (th)/(h·m·°C) = 1.162222 watt per meter kelvin (W/(m·K))
Step-by-step substitution for Watt/meter/degree Celsius → Kilocalorie (th)/hour/meter/°C:V(kcal (th)/(h·m·°C)) = V(W/(m·°C)) × ( 1 / 1.162222 ) = V(W/(m·°C)) × 0.860421

Worked Example

To convert 24 Watt/meter/degree Celsius (W/(m·°C)) to Kilocalorie (th)/hour/meter/°C (kcal (th)/(h·m·°C)): multiply 24 by 0.860421 to get 20.650096 kcal (th)/(h·m·°C). At an industrial engineering scale, 240 W/(m·°C) converts to 206.500956 kcal (th)/(h·m·°C).
