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

    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.
