not correct unit

Oh, and please post a worksheet containing your problem, if possible.  It saves others from typing out what you've written.  Or, rather, what you appear to have written.  There are some subtle typographical conventions that Mathcad employs that can make it difficult to see precisely what you've typed, and that may be causing your problems.

Square v(t) not sin only.

@StuartBruff 

The whole expression under the root is squared, not just the sine. So the result actually IS volt

The result you get is correct, but Prime choses to dispplay it using the base units of the units system you have chosen.

You always can override this by simply editing the units and replacing them with the unit(s) you would like to see. If necessary Prime will automatically change the number in front accordingly or add additional units if necessary.

@ttokoro had just shown with a screen how it look like when you change the expression in the unit placeholder of the result to V

Some examples:

EDIT:

Ahhhh!!!!

I just noticed what the problem is.

When it comes to volt, it should not be necessary to manually change it , unless ....

...unless you checked the "Base Units" button in the "Units" menu on the "Math" ribbon!

Uncheck that button and you should see "volt" immediately 🙂
