REALLY HANDY volume calculator - links to other converters, too. Goes hand in hand with this link. If/when you need it, it’s so cool:

Go to a library and look at a copy of “Machinery’s Handbook”. look under wire and sheetmetal gages – gives some explanations

This chart does not check out with others— Hoover and Strong, McCreight, Rio Grande. The US uses the Brown and Sharp system and I Believe most everyone else uses metric measurements. A few sizes conflicted with memory… then they don’t seem to really check out … This chart seems to be for the Birmingham iron wire measuring system. There are at least 8 wire gage systems and several systems for sheet metal that are all a bit different. Even the old Machinery’s handbook 1966 edition recognized the problem and recommended using decimal measurements when specifying material. The old stuff hangs on in some industries with a resulting need to always check things out when just a gage number is specified. jesse

You are doing the right thing with decimals. In the US the Brown and Sharpe system is the one to use but there are exceptions in some industries with some materials.

A bearing number is composed of a basic number and a supplementary code, denoting bearing specifications including bearing type, boundary dimensions, running accuracy, and internal clearance. Bearing numbers of standard bearings corresponding to JIS B 1512 "rolling bearing boundary dimensions" are prescribed in JIS B 1513. As well as these bearing numbers, JTEKT uses supplementary codes other than those provided by JIS. Among basic numbers, bearing series codes are listed in Table 6-1 Bearing series code, and the composition of bearing numbers is described in Table 6-2 Bearing number configuration, showing the order of arrangement of the parts.

I based my chart on Small Parts Company’s catalogue from whom I buy my drill tube which I use to make ultrasonic drill bits for drilling gems.

[Notes] 1) Width series codes in parentheses are omitted in bearing series codes. 2) These are bearing series codes customarily used. 3) Nominal outer ring width series (inner rings only are wide). 4) Besides NU type, NJ, NUP, N, NF, and NH are provided.

I will make a new chart adding that gauge system. Please post a few comparative conversions (gauge to inch) from your info so I/we can see what the difference is.

I used to measure and label all my ultrasonically drilled hole diameters using inches. (i.e…e. 0.018", 0.020", 0.025" etc.) but many jewelers complained and wanted a gauge measurement. Now It seems I have been basing my conversions on the wrong gauge system. What is the gauge system American jewelers use? What about the rest of the world, do you use gauge, metric, or… ?

I think you are right, I have always been under the impression that one was for non ferrous (sp?) metals and the other was for ferrous.

I copied their small diameter stainless tubing chart -gauge to inch conversion- as the initial basis for my chart. I then added the metric portion based on a 25.4 mm to the inch conversion.
