What is the thingy called

[AvvaRae]

😎Can someone help me understand what that size thingy I see everyone using when they are identifying size? I was reading an archived thread that WVRON stated size is almost always needed in identification. The information he had there on sizes and makes sort of felt invaluable to me to be able to move forward in helping myself learn to ID on my own. 

 

Any help would be greatly appreciated. ☺️

"Calipers" I get mine from Harbor freight, I found the plastic ones easy on glass and accurate enough for marbles (& they're cheap). Make sure you get the ones that measure in "fractions of an inch" Most sets measure in inches, fractions of an inch and mm. Here is a link for ya !!

The top is inches and fractions of an inch & the bottom is mm. These will measure inside and out side diameter, outside is for marbles and such and inside is for measuring the diameter (width) of a hole. W/ marbles all you'll be dealing w/ is the top of the caliper ( inches & fractions of an inch) not many use mm, mostly out of the continental US. The mib pictured is 27/32nds of an inch, don't worry, you'll catch on fast
