Thank you Michael.

To mindset, Re: micron:
Did a little google search,
micron = micrometre = micrometer = µm.
micron = 1 X 10power(-6) = .000001 metre = .000001 meters
meter belong to one of the 7 classes of SI units

Just using µ alone means "millionth. (I am unsure of the convention of using µ, rather than µm.

Inserting µ in the Text field is just text to display. It does not "re-program" MoI.
