How to Convert Kilowatt per Square Metre Kelvin to kcal/(h·m²·°C)
- 1 kW/(m²·K) = 859.8452279 kcal/(h·m²·°C)
- 1 kcal/(h·m²·°C) = 0.001163 kW/(m²·K)
- Example: convert 15 kW/(m²·K) to kcal/(h·m²·°C): 15 kW/(m²·K) = 15 × 859.8452279 kcal/(h·m²·°C) = 12897.67842 kcal/(h·m²·°C)
Reference conditions. kcal/(h·m²·°C): International Table kilocalorie (4186.8 J), as used in engineering heat transfer data
Formula
kcal/(h·m²·°C) = kW/(m²·K) × 859.845227859
Derivation from SI units:
- 1 kW/(m²·K) = 1000 W/(m²·K)
- 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) ÷ 1.163 W/(m²·K) per kcal/(h·m²·°C) = 859.845227859 kcal/(h·m²·°C)
Both units are defined exactly, so the factor is exact. Kilowatt per Square Metre Kelvin definition: kilowatt per square metre kelvin; kcal/(h·m²·°C) definition: kilocalorie per hour square metre degree Celsius.
Worked examples
- A reading of 2 kW/(m²·K) converts to 1719.690456 kcal/(h·m²·°C).
2 kW/(m²·K) × 859.8452279 = 1719.690456 kcal/(h·m²·°C) - A value of 10 kW/(m²·K) is 8598.452279 kcal/(h·m²·°C).
10 kW/(m²·K) × 859.8452279 = 8598.452279 kcal/(h·m²·°C)

Where it's used
Kilowatts per Square Metre Kelvin are used for shell-and-tube and plate heat exchangers, while kilocalories per hour square metre degree Celsius appear in older metric heat exchanger and boiler data. Both measure heat transfer coefficient (h) and thermal transmittance (U-value), so the conversion is a fixed factor.
