How to Convert Watt/Meter-Kelvin to Kilocalorie/Hour-Meter-°C

To convert from Watt/Meter-Kelvin (W/(m·K)) to Kilocalorie/Hour-Meter-°C (kcal/(h·m·°C)), multiply the value by 0.8598452279.

Formula: kcal/(h·m·°C) = W/(m·K) × 0.8598452279

Reverse: W/(m·K) = kcal/(h·m·°C) × 1.163

Step-by-Step Example

Start with your value in Watt/Meter-Kelvin. For example: 5 W/(m·K)
Multiply by the conversion factor: 5 x 0.8598452279
The result is: 4.299226 kcal/(h·m·°C)

About Watt/Meter-Kelvin

The watt/meter-kelvin (W/(m·K)) is a unit of thermal conductivity. One watt/meter-kelvin equals 1 base unit. UnitConvertLab converts it against every other thermal conductivity unit using this exact definition, so results are reproducible to full double precision rather than rounded lookup tables.

Common uses: thermal conductivity calculations, engineering and science, education.

About Kilocalorie/Hour-Meter-°C
