of Staples or other like store. You will find rulers with a side marked in 1/50". Plenty accurate, I have 2 of them.

The Metric system is great for weight, mass, temperature etc. However for units of length it is counter-intuitive. It "seems" like a MM is just some arbitrary unit of measurement. Whereas an inch is 1/12 of a foot. If I want to know how long a foot is I (ahem), just look at my foot!

I'm with Mattia on this one... a measurement like .125in means absolutely nothing to me - I couldn't even venture a guess on how thick that is if it weren't for all the bassists I do repairs for.

If we're talking about something like a soundboard, then measuring in inches is just too much. For fun, I just grabbed three soundboards - bookmatched this is six pieces of wood, and the combined thickness of all six pieces is just over an inch. I find it hard to understand why someone would want their point of reference (one inch... since we're dividing that into either fractions or decimals) to be so much bigger      (thicker) than the not yet thinned pieces they are working with.

A millimeter on the other hand is much easier, because it is one unit... with one name, not half of something else (though 10 of them and you have a centimeter). Once you introduce the decimal to it, for say a soundboard - you're dealing with a number like 1.9 or 2.2, which is much easier to determine percentage differences between measurements. A mm just seems like a much better reference point than an inch.

Granted, I learned guitar making with millimeters, and it seems the standard with classical guitars. So I have a definite bias since all the important measurements for braces and plates are generally in mm. But its still just a lot easier to deal with 2.2 instead of .125 or whatever. The reference is just too far off... its like measuring your driveway in terms of miles rather than yards or feet. Just my opinion though.
