wire size

[piannaman at aol.com]

 Michelle,
 
A good way to remember without a chart:
 
Subtract 5 from the thickness, then divide by two, and voila!  The wire size  
 
(41-5+36, 36 divided* by 2 = 18)

*how DOES one get the division symbol on a computer keyboard??

Michelle, 

Dave beat me to it but here's a chart you might like to keep handy. 
I have one similar hanging on a wall in my shop. I can also send it
to in Excel if you can open that.

 Michelle,
 
That would be correct.  Wire that thick can have a mind of it's own!

I’m new at this game Avery so please tell me if I’m wrong.  I just measured the scrap string I took off the piano at .041.  Am I correct that this would be a size 18?
 
It’s a giant old piano.
 
Thanks!
 
Michelle

Wow. That seems awfully big for middle C. You sure it wasn't a lower note?
