Re: Thickness of thousands of an inch

hi SuperLynx

I'm guessing you mean 3/1000 of an inch and not 0.003 thousandths = 0.000003 as that would be too small to see. 

It's a tough one.  I checked out the size of guitar strings and it seems the thinnest string is typically 0.008 inches.

Feeler gauges are used by engineers to judge gaps in machines (eg.  spark plug gap) so you might ask a car mechanic to show you one.

Human hair varies from person to person with an average around 0.004 inches.  So you need to find someone with fine hair.

Hope that helps.  Happy Christmas!

The plank's length is still smaller.
