Assume measurement accuracy to "within 43 arc seconds" per century.
Assume 1 Earth century = 415 Mercury orbits
~~~~~~
415 orbits * 360 degrees = 149400 degrees per century
149400 degrees * 60 arc minutes = 8964000 arc minutes per century
8964000 arc minutes * 60 arc seconds = 537840000 arc seconds per
century.
43
-------------------------------- = 0.0000000799494273389855719 =

Are we all on the same page so far?
Sure.
If so, what the hell am I missing when 7.9949E-8 parts out of 100 is
not equal to 7.9949E-6 percent?
N parts out 100 is N %. N = N.
It is, but that is not what he is saying.
7.9949E-8 times 100 is not 7.9949E-6 percent
It is
7.9949E-6
and it is
7.9949E-4 percent
Am I suffering from a brain embolism here or something?? 'Cause it's
either that or I'm completely missing the point of

For the love of god, help!
The point is that the engineer doesn't understand what percentages are.
Do you understand the meaning of the percent-sign?

Hah...obviously not.
% is an abreviation of 1/100
Assume a 15 question quiz. You answer 11 correct out of 15. Your
percentage score is:
11/15 = .73/1 = x/100.
Yes.
11/15 = 11/15 * 1
= 11/15 * 100 %
= 73.1 %
and that should be all there is to it.
