Mathcad understands percent, what about ppm?

Mathcad understands percent, what about ppm?

Hi, completely new to MathCad (using MathCad prime 6.0).  I'm doing some engineering work and simply need MathCad to understand "ppm".  I've tried to find a solution on this forum and via google to no avail.

 

For example, I can assign "25%" to a variable and when I output that variable I get 0.25.  But when I assign "25ppm" to a variable, it doesn't understand.  Any suggestions?

 

Thank you,

Erik

That'll do, thanks very much for the help.

Additional note:

Make sure that you define ppm with the label of 'unit', rather than 'variable'.

By default, in Prime it will be(come) blue, bold and italic: ppm.

I can only second what Lucs suggested.

Its only when ppm is defined (labelled) as "Unit" that you can use it the other way round, too.

Even better, thanks!

 

And for other noobs out there who run across this, you need to apply a label to the "ppm", so it becomes blue color.  Do this by going to Math->Style and then use the drop down to change from "variable" to "label".
