Also factory manual states the alignment tolerances in degrees, mm and inches and lists the following:

rear toe: -6' to 18 deg = -1 to 3mm = -0.04 to 0.12in

Now assuming that those numbers are all relative conversions of each other for whatever type of alignment equipment was being used that would put my alignment as reported for the rear to be within tolerances.

Does your formula relate specifically to the adjustment range of a product, rather than to a conversion based on specifications on a wheel alignment sheet?

Sorry if the question is stupid, but i'm just a little confused, maybe i'm interpreting the data wrongly or applying it wrongly?
Degrees are always the same - 360 degrees in a full rotation. You might have applied the math incorrectly to your situation? It's important to understand the way the aligner measured your toe. That said, I found my rear wheels were 23mm toe out per side and that isn't EXTREMELY obvious to my eye, because the side skirts don't represent a perfect parallel to the centreline.

Either way 6 or 7 degrees is probably heaps too much toe for a street car (90 degrees would be sideways toe! - Think of it that way). Maybe ask your aligner how/usig what method they measured the toe and if they could provide that in mm?
