How to Convert Watt/meter/kelvin to Kilocalorie (IT)/hour/meter/°C

Converting Watt/meter/kelvin (W/(m·K)) to Kilocalorie (IT)/hour/meter/°C (kcal/(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 (IT)/hour/meter/°C is a broader physical scale than Watt/meter/kelvin, converting from W/(m·K) to kcal/(h·m·°C) condenses the numerical figure. It takes 1.163 Watt/meter/kelvin to equal a single Kilocalorie (IT)/hour/meter/°C (1 W/(m·K) = 0.859845 kcal/(h·m·°C)). To convert any quantity, multiply by 0.859845 (or divide by 1.163).

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·K) = 1 watt per meter kelvin (W/(m·K))
2. Target SI Bridge (ktarget):1 kcal/(h·m·°C) = 1.163 watt per meter kelvin (W/(m·K))
Step-by-step substitution for Watt/meter/kelvin → Kilocalorie (IT)/hour/meter/°C:V(kcal/(h·m·°C)) = V(W/(m·K)) × ( 1 / 1.163 ) = V(W/(m·K)) × 0.859845

Worked Example

To convert 2.5 Watt/meter/kelvin (W/(m·K)) to Kilocalorie (IT)/hour/meter/°C (kcal/(h·m·°C)): multiply 2.5 by 0.859845 to get 2.149613 kcal/(h·m·°C). At an industrial engineering scale, 10000 W/(m·K) converts to 8598.452279 kcal/(h·m·°C).

Inverse check: 1 kcal/(h·m·°C) = 1.163 W/(m·K).
