Inch to mm conversion with +1,2,3,4 inches.
So fellow Americans, if you go to the store for a fitting or whatever, how do you know that 3/16 is bigger than 11/64, for example. Do you have to pull the calculator, or is there any quick mental trick? Or you get used to it. More on reddit.com

is there any difference between a 3.5mm jack and 1/4 inch jack?

No, it doesn't decrease sound quality. The larger 6.3mm input port might be a little longer lasting, and the male jack that fits into it is less prone to bending in an accident.

3.5 mm Audio Plug
It wasn't long ago, that the 3.5 mm and 2.5 mm Audio Plugs had an USC dimension. I believe the 3.5 mm was called 1/8 inch. Question? What it ever 1/8 inch or was that just the closest trade name to 3.5 mm? 1/8 in = 0.125 inch = 3.175 mm. 3.175 mm or 3.2 mm is much closer to 3 mm than 3.5 mm. Since the two numbers are not even close and the one would be out of tolerance with the other, what is the true size of this plug? Here is also the standard 2.5 mm: https://www.futurlec.com/Audio-Phono.shtml Was this once called a 3/32 in inches or something else? Again, here is a list of 6.5 mm, also called 1/4 inches. Which is the true dimension? https://www.futurlec.com/Audio-65mm.shtml There is an answer on Wikipedia: http://en.wikipedia.org/wiki/Phone_connector_%28audio%29 But I'm not sure if they are right or not and would hope to hear from other sources. Especially concerning the 6.5 mm plug. The Chinese are notorious (in a good way) for adapting inch based products to rounded metric. They put metric heads on inch threaded bolts, could they have also changed the 6.35 mm plug to a 6.5 mm plug? More on reddit.com
