Universal system of measurements


#1
1mm wire is approximately 18 ga. and if this is a bracelet you
probably need to use at least 16 ga. wire. 

What wire gauge is this please?

I’ve just referenced http://www.clag.org.uk/swg.html which says that
18 SWG is 1.219mm. 19 SWG is 1.016 and 20 SWG is 0.914mm, both of
which are closer to 1mm.

I’m in UK and gave up using “standard gauges” because there are so
many different ones. For example, this website lists 5 different
ones. http://www.dave-cushman.net/elect/wiregauge.html

Please, why can’t we all use a universal, non-ambiguous, system of
measurement, such as inches or millimetres?

(The good thing about standards is that there are so many to choose
from.)

Hi Gary,

It was probably B&S gauge. (Brown & Sharp) That’s what we (normally)
use for non-ferris metals in the states. Of course, there’s always
ASW (American Standard Wire…) which is (officially) used for
ferris metals. (Of course they’re different…)

Working in London, Birmingham gauge threw me for a loop the first
time I ran across it, as it runs backwards to the two aforementioned
systems…

I’m with you: I normally specify things either in thousandths of an
inch, or mm, depending on who I’m talking to.

Regards,
Brian.

Call me old school but I think in decimal inches. Tell me something
is .062" and I know precisely what it is. MM or Ga and I have to
consult a chart. For instance, there is no gauge equivalent to .030",
a most common dimension in the trade. Also, the dimensional
increments in Gauge have no consistency, big drag.

Although I don’t use them myself, I have no objection to anybody
using wire gauges to define diameters, but I do object when the
particular standard is omitted. It would be OK if there was only one
wire gauge, but there are lots of them. It’s rather like saying that
the length of something is 12. 12 what? Inches, metres, chains,
cubits, etc.

Personally, I use millimetres. They are a closer match for jewellery
sized objects than are inches, and they don’t need as many decimal
places.

I thought that jewelry supply merchants in the twenty first century
measured the diameter of nonferrous wire in either millimeters or
AWG. Do they still use SWG in the UK for nonferrous wire?

5? I was warned that there were up to 14 different gauges at one
time and was taught to rely on hard numbers such as thousandth’s of
an inch or metric sizes. I had to relearn gauges so I could converse
with people who only knew gauge numbers, but I still use real sizes
when buying my own stock.
