Output a temperature in Excel-File in degrees Celsius

Hi everyone,

When I want to put a variable in an Excel-file, but with non standard units, for example mm instead of meters, I simply divide it in the input field (see example).  But what about a temperature? I have tried different ways but without success.

It always comes out as Kelvin.  I would like Celsius °C.

Basically the question is: how do I "adimensionalize" a temperature, that is reduce the value of temperature to a simple number, without units?

Thanks a lot in advance

Best regards

Claudio
