How to Convert kcal/(h·m·°C) to Watt per Metre Kelvin
- 1 kcal/(h·m·°C) = 1.163 W/(m·K)
- 1 W/(m·K) = 0.8598452279 kcal/(h·m·°C)
- Example: convert 0.03 kcal/(h·m·°C) to W/(m·K): 0.03 kcal/(h·m·°C) = 0.03 × 1.163 W/(m·K) = 0.03489 W/(m·K)
Reference conditions. kcal/(h·m·°C): International Table kilocalorie (4186.8 J), as used in engineering heat transfer data
Formula
W/(m·K) = kcal/(h·m·°C) × 1.163
Derivation from SI units:
- 1 kcal_IT/(h·m·°C) = 4186.8 J ÷ (3600 s × 1 m × 1 K) = 1.163 W/(m·K) (exact)
- The SI unit of thermal conductivity: heat flow (W) per metre of thickness per kelvin of temperature difference
Both units are defined exactly, so the factor is exact. kcal/(h·m·°C) definition: kilocalorie per hour metre degree Celsius; Watt per Metre Kelvin definition: watt per metre kelvin.
Worked examples
- Insulation at 0.03 kcal/(h·m·°C) is 0.03489 W/(m·K).
0.03 kcal/(h·m·°C) × 1.163 = 0.03489 W/(m·K) - Steel at about 40 kcal/(h·m·°C) is 46.52 W/(m·K).
40 kcal/(h·m·°C) × 1.163 = 46.52 W/(m·K)
