Mathcad Prime 3.1 or 4.0 worksheet default unit setup

[dtran]

As a user in Mathcad 15 and below, I know how to setup the default unit system for mathcad worksheet. For instance, Length = inch, time = s mass = lb force = lbf, pressure = psi.

When I calculate such as Force/ Area, the unit of the answer is psi.When I try to do a very simple test in Prime 4, the unit always is always wrong..

How can I do the same task in Mathcad Prime?

What do you mean with 'wrong'?

You divide force by area and do not get a pressure unit (such as Pascal, or N/m^2)....?

Oh, you want this:

Then set your unit system right:

Success!
