Hello, I'm going to post a curious question. Today I found a case where I have no idea what to do. I'm working with the Thermal Conductivity and it's W/(m ºC) or W/(m K) then I don't know how to change from a way to the another one because kelvin and Celsius degrees are not proportional. All my time in my studies I usually worked with Celsius degrees. When I had Kelvin I had the constants or variables in the appropriate units. Can you help me with this? Thank you.
