problem defining a function that has variables with units of measure

I tried to define the function so that all the units of measure would cancel out and one would produce a dimensionless mass fraction but MathCAD thinks I am doing it incorrectly.

Please explain what I am doing wrong or provide a workaround.

Thanks!

°C is actually a function that converts your input to a temperature. Mathcad has to treat °F and °C differently than the other temperature units because they are not zero-based (not sure this is the right terminology).

Because °C is a function and not a unit, you cannot just divide by °C. You need a function that gives you the inverse temperature. You can write your own function like this:
