How to Convert kcal/(h·m·°C) to Milliwatt per Metre Kelvin
- 1 kcal/(h·m·°C) = 1163 mW/(m·K)
- 1 mW/(m·K) = 0.0008598452279 kcal/(h·m·°C)
- Example: convert 15 kcal/(h·m·°C) to mW/(m·K): 15 kcal/(h·m·°C) = 15 × 1163 mW/(m·K) = 17445 mW/(m·K)
Reference conditions. kcal/(h·m·°C): International Table kilocalorie (4186.8 J), as used in engineering heat transfer data
Formula
mW/(m·K) = kcal/(h·m·°C) × 1163
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)
- 1 mW/(m·K) = 0.001 W/(m·K)
- 1 kcal/(h·m·°C) = 1.163 W/(m·K) ÷ 0.001 W/(m·K) per mW/(m·K) = 1163 mW/(m·K)
Both units are defined exactly, so the factor is exact. kcal/(h·m·°C) definition: kilocalorie per hour metre degree Celsius; Milliwatt per Metre Kelvin definition: milliwatt per metre kelvin.
Worked examples
- A reading of 0.05 kcal/(h·m·°C) converts to 58.15 mW/(m·K).
0.05 kcal/(h·m·°C) × 1163 = 58.15 mW/(m·K) - A value of 1.2 kcal/(h·m·°C) is 1395.6 mW/(m·K).
1.2 kcal/(h·m·°C) × 1163 = 1395.6 mW/(m·K)

Where it's used
kcal/(h·m·°C) are used for older metric heat transfer and insulation tables, while milliwatts per metre kelvin appear in insulation product data (λ-values). Both measure thermal conductivity (k, λ), so the conversion is a fixed factor.
