topic Manipulate equation range result units in PTC Mathcad

<P>I am working on an electrical arc-flash calculation using the NFPA70E method. I have defined a voltage range (<STRONG><FONT color="#3366FF">in blue</FONT></STRONG>) for the calculation and I would like to plot arc-flash vs voltage (this is obviously linear so it is not critical but I would like to know if there is a way to do this for future calculations). The problem I ran into is converting the result of the equation (<STRONG><FONT color="#339966">in green</FONT></STRONG>) to the unit I want (cal/cm^2) over the entire voltage range (<STRONG><FONT color="#3366FF">in blue</FONT></STRONG>). I can convert the result at individual voltage (<STRONG>in black</STRONG>) to the unit I want (cal/cm^2) but if i try to display the result at 550 volts (<STRONG><FONT color="#FF0000">in red</FONT></STRONG>) it displays in kg/s^2 which is not the unit I want. I have to manually change the unit to cal/cm^2.</P>

<P>It would be great is anyone can assist with this.</P>
