How to Convert kcal/(h·m²·°C) to Kilowatt per Square Metre Kelvin
- 1 kcal/(h·m²·°C) = 0.001163 kW/(m²·K)
- 1 kW/(m²·K) = 859.8452279 kcal/(h·m²·°C)
- Example: convert 15 kcal/(h·m²·°C) to kW/(m²·K): 15 kcal/(h·m²·°C) = 15 × 0.001163 kW/(m²·K) = 0.017445 kW/(m²·K)
Reference conditions. kcal/(h·m²·°C): International Table kilocalorie (4186.8 J), as used in engineering heat transfer data
Formula
kW/(m²·K) = kcal/(h·m²·°C) × 0.001163
or kW/(m²·K) = kcal/(h·m²·°C) ÷ 859.845227859
Derivation from SI units:
- 1 kcal_IT/(h·m²·°C) = 4186.8 J ÷ (3600 s × 1 m² × 1 K) = 1.163 W/(m²·K) (exact)
- 1 kW/(m²·K) = 1000 W/(m²·K)
- 1 kcal/(h·m²·°C) = 1.163 W/(m²·K) ÷ 1000 W/(m²·K) per kW/(m²·K) = 0.001163 kW/(m²·K)
Both units are defined exactly, so the factor is exact. kcal/(h·m²·°C) definition: kilocalorie per hour square metre degree Celsius; Kilowatt per Square Metre Kelvin definition: kilowatt per square metre kelvin.
Worked examples
- A reading of 20 kcal/(h·m²·°C) converts to 0.02326 kW/(m²·K).
20 kcal/(h·m²·°C) × 0.001163 = 0.02326 kW/(m²·K) - A value of 500 kcal/(h·m²·°C) is 0.5815 kW/(m²·K).
500 kcal/(h·m²·°C) × 0.001163 = 0.5815 kW/(m²·K)

Where it's used
kcal/(h·m²·°C) are used for older metric heat exchanger and boiler data, while kilowatts per square metre kelvin appear in shell-and-tube and plate heat exchangers. Both measure heat transfer coefficient (h) and thermal transmittance (U-value), so the conversion is a fixed factor.
