I am working on an electrical arc-flash calculation using the NFPA70E method. I have defined a voltage range (in blue) 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 (in green) to the unit I want (cal/cm^2) over the entire voltage range (in blue). I can convert the result at individual voltage (in black) to the unit I want (cal/cm^2) but if i try to display the result at 550 volts (in red) it displays in kg/s^2 which is not the unit I want. I have to manually change the unit to cal/cm^2.
