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?
