That's what I have explained before: maths are unitless.
Units is an associated math system, each procssing.
I can see Mathcad 15 was modified [after my war against units].

Did you see my last screen shot?

For some reason , units outside the brackets of the vector, are causing the problem in the transposition of the vector

You keep "defining" *modified values* - like here: you try to "define" what "transposed Q" is.
This is what you actually do:

transpose(Q):mat(50,80,1,2)*'gal/'min

Don't you see what's going on? Yes, you simply override built-in transpose. Everything is correct.

In this case ... no, I did not notice the ":=" on the Transpose of Q (too fast for my own good!). I was having this happen on 5 other sheets ... This was a sample. I will check the other sheets to see if i did the same thing. Thanks for pointing that out
