And, btw, for center pins, subtract 10 and divide by 2.  Example. Center
pin mics at .050.  (50-10)/2 = #20 center pin.  
 
Yes, they do ask those on the RPT exam, or at least they did.

Guys...
 
Forget the .033, just think of it as 33, OK?   Subtract 5 = 28, divide
by 2 = 14 wire size.

0.033 inches = -2.4835 wire size?

Micrometer reading - 5 , and divide by 2.     Gw=(d-5)/2
 
Hope that helps..

Greetings,
 
Would someone be kind enough to tell me the formula for calculating  the
string size with the reading you get from the micrometer measurement?
I.E. if the mic tells me the thickness is .033 of an inch, What is the
string size?
 
Thank you in advance
 
Mark
