Possibly not with your original result matrix, if you shall use results later.
It can be shown in a table region or another pseudo result matrix.
Here is the table method.

Here is your matrix with pseudo units.
Not very elegant, but it is there.

Hello,

How do I set my units so my answers are in the unit I want, at the moment the answer is being returned to Pa (Pascal) and I would prefer to have the answer in kPa(KiloPascal) or even kN/m^2.

I am also getting answers in N(Newtons) and would prefer to have them set to kN (Kilo Newton) rather.

Your attached document is fine. Jean's computer is broken.
About your question, there is a placeholder within results.
It will appear when you select result. It appears as a black square.
You can change your desired result units by altering it.
Here is a demonstration how you can do that.

Regards
