Kcal per hour-meter-°C to watts per meter-kelvin
Type a value in kcal/(h·m·°C) to get it in W/(m·K) instantly.
That's 1.16× as conductive as glass, while concrete is 1.46× higher. Through a 10 cm slab with 20 °C across it, that carries about 232.6 W per square meter.
Convert the other way: W/(m·K) to kcal/(h·m·°C)
What it means
How fast does heat cross?
Values are at room temperature. Conductivity changes with temperature, moisture and, for insulation, with age.
The math
How to convert kcal/(h·m·°C) to W/(m·K)
To convert kcal per hour-meter-°C to watts per meter-kelvin, multiply by 1.163.
Example: 1 kcal/(h·m·°C) × 1.163 = 1.163 W/(m·K).
In the other direction, 1 W/(m·K) = 0.859845 kcal/(h·m·°C).
