How to Convert Watt per Metre Kelvin to kcal/(h·m·°C)
- 1 W/(m·K) = 0.8598452279 kcal/(h·m·°C)
- 1 kcal/(h·m·°C) = 1.163 W/(m·K)
- Example: convert 15 W/(m·K) to kcal/(h·m·°C): 15 W/(m·K) = 15 × 0.8598452279 kcal/(h·m·°C) = 12.89767842 kcal/(h·m·°C)
Reference conditions. kcal/(h·m·°C): International Table kilocalorie (4186.8 J), as used in engineering heat transfer data
Formula
kcal/(h·m·°C) = W/(m·K) × 0.859845227859
or kcal/(h·m·°C) = W/(m·K) ÷ 1.163
Derivation from SI units:
- The SI unit of thermal conductivity: heat flow (W) per metre of thickness per kelvin of temperature difference
- 1 kcal_IT/(h·m·°C) = 4186.8 J ÷ (3600 s × 1 m × 1 K) = 1.163 W/(m·K) (exact)
Both units are defined exactly, so the factor is exact. Watt per Metre Kelvin definition: watt per metre kelvin; kcal/(h·m·°C) definition: kilocalorie per hour metre degree Celsius.
Worked examples
- A reading of 0.15 W/(m·K) converts to 0.1289767842 kcal/(h·m·°C).
0.15 W/(m·K) × 0.8598452279 = 0.1289767842 kcal/(h·m·°C) - A value of 16 W/(m·K) is 13.75752365 kcal/(h·m·°C).
16 W/(m·K) × 0.8598452279 = 13.75752365 kcal/(h·m·°C)

Where it's used
Watts per Metre Kelvin are used for insulation λ-values (EN 12667, ISO 8301), while kilocalories per hour metre degree Celsius appear in older metric heat transfer and insulation tables. Both measure thermal conductivity (k, λ), so the conversion is a fixed factor.
