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

Converting Watt/meter/kelvin (W/(m·K)) 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/kelvin, converting from W/(m·K) to kcal (th)/(h·m·°C) condenses the numerical figure. It takes 1.162222 Watt/meter/kelvin to equal a single Kilocalorie (th)/hour/meter/°C (1 W/(m·K) = 0.860421 kcal (th)/(h·m·°C)). To convert any quantity, multiply by 0.860421 (or divide by 1.162222).

Direct Factor1 W/(m·K) = 0.860421 kcal (th)/(h·m·°C)

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:

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 W/(m·K) = 1 watt per meter kelvin (W/(m·K))

2. Target SI Bridge (k_target):1 kcal (th)/(h·m·°C) = 1.162222 watt per meter kelvin (W/(m·K))

Step-by-step substitution for Watt/meter/kelvin → Kilocalorie (th)/hour/meter/°C:V(kcal (th)/(h·m·°C)) = V(W/(m·K)) × ( 1 / 1.162222 ) = V(W/(m·K)) × 0.860421

Worked Example

Converting 36 W/(m·K) yields an exact output of 30.975149 kcal (th)/(h·m·°C) in Kilocalorie (th)/hour/meter/°C. Under higher industrial throughput, 2500 W/(m·K) translates to 2151.052037 kcal (th)/(h·m·°C).

Inverse check: 1 kcal (th)/(h·m·°C) = 1.162222 W/(m·K).
