.110 * 25.4 = 2.794mm

Rahoul,
I've built only classicals to date, and have thinned my bridge plates to 1/16 inch or approximately 1.6 mm. In a recent thread on this forum regarding soundboard bracing, I remember that a couple of classical builders reported that they have built without a bridge pad at all. As a novice, however, I will stick with a thin spruce pad for now.

I roll at about 0.100" of steel string instruments. I use Maple... rift sawn.

25.4 mm in an inch. Remember that if nothing else!

I'm horrible at math and never really got the hang of metrics so I cheat...

I have a couple of rulers that have all the conversions on the back and have a little converter program on my pc and my phone.

For those Windows users that are math challenged like me here is a free utility that I used forever. It will convert almost anything to anything

.100"-ish for me.

My memory key for mm conversion is 1mm = .040" (actually .03937", but close enough). So .100" is about 2.5mm.

I use to convert inch to metric, then i realized digital calipers will do it for you.
I use to prefer vernier calipers but now I have to keep a pair of digital's around.

I have to do it constantly at work. Just remember 25.4 (mm per inch) although most electronic calipers make it easy if they're in your hand.

I just Google it. "Inches to MM," or "MM to Inches." Google spits it right out.

FWIW, my bridge plates are usually .09"

This thread reminds me of the time I was cutting a shelf and a guy was giving me the exact measurement. He said its 36", plus a 1/4, plus 1/8, and 1 of those little marks. :)

I also do 3/32in or .01in for steel string and 1/16th for classical's. Though these days I don't use a patch for classicals anymore.

660 ft/furlong x 12 inches/foot x 0.0000138 furlongs = 0.109" because who cares about feet idunno

I think you make a couple of valid (decimal) points there, Steve. ;)

For those of us not in the three remaining countries not using the metric system (Liberia, Myanmar, USA) here it is in km's: 0.000003. I hope that wasn't too political ;)

It was an attempt at humor. Obviously not a good attempt. :)
