How to measure really small hole diameter
How do I *accurately* (n.nnnn) measure very small hole diameters?
I can poke them with a numbered drill but that would only get me close by
"feel" and only if the hole was a standard size. e.g. measureing a .0431
hole is kind of hard with a vernier or mic
No real reason - enquiring minds just want to know

Depending on the material, you may need to specify the temperature at which you
are measuring if you need to have 4 decimal accuracy.
