cal/(s·cm·°C)
calorie per second centimeter Celsius
Thermal conductivityexact by definition
The calorie per second centimeter Celsius is exactly 418.4 W/(m·K) on the thermochemical calorie. It is the CGS conductivity unit of the older physics and metallurgy literature; copper is 0.94 in it, which is the form most pre-1970 handbooks print.
Watch out: Sources built on the IT calorie of 4.1868 J give 418.68 instead. The 0.07% difference is below the accuracy of most conductivity measurements but will make two handbooks disagree in the last digit.
