What Is This Tool?
This converter allows you to transform thermal conductivity measurements expressed in kilowatt per meter per kelvin (kW/(m*K)) into kilocalorie (IT) per hour per meter per degree Celsius (kcal/(h·m·°C)). It is useful for comparing thermal properties across SI and non-SI unit systems commonly found in building materials, HVAC design, and engineering applications.
