Watts per meter-kelvin to kcal per hour-meter-°C
Type a value in W/(m·K) to get it in kcal/(h·m·°C) instantly.
That's about the same as glass. Through a 10 cm slab with 20 °C across it, that carries about 200 W per square meter.
Convert the other way: kcal/(h·m·°C) to W/(m·K)
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 W/(m·K) to kcal/(h·m·°C)
To convert watts per meter-kelvin to kcal per hour-meter-°C, multiply by 0.859845.
Example: 1 W/(m·K) × 0.859845 = 0.859845 kcal/(h·m·°C).
In the other direction, 1 kcal/(h·m·°C) = 1.163 W/(m·K).
