Per one source release was 500 microns
I suggest to my colleagues that they are missing the obvious. It turns out that "microns" is just an abbreviation for a groundbreaking new unit of measurement. Being a scientist (among other things), nads clearly feels justified in subjecting scientist and laymen the world over to her own standardized unit of measure: the Micronad.
The Micronad can mean anything at any moment, for as long as necessary, and then change back in an instant without warning, justification, or relation to previous definitions. It can be applied to the laws of the quantum mechanics, psychics, mathematics, chemistry, astronomy, animal husbandry, political philosophy, and anywhere else nads sees it fit and necessary to apply. In short, the Micronad is the Calvinball of units of measure:

With this invention/discovery, nads has propelled herself into the upper echelon of scientific measurement work, alongside John Wilkin, Anders Celsius, Lord Kelvin, Daniel Fahrenheit, Et al.
