Why are you bothering with metric? Imperial is so much easier - it's just
common 37/363 inch wire.
In metric it'd be 2.6mm, but god knows what that means. Keep in mind that
metric wire *will* be less reliable.
Care to shed some light on this statement ? Why would be metric piano
wire be less reliable than imperial of same dia ?
Tnx for size...

Actually "10 Gauge" wire has several different sizes --
British Imperial std wire shows .160" or 4.064 mm

There are a bunch of different gauges. He is probably referring
to American Wire Gauge (AWG) and 10 gauge is about 1/8". AWG is used
almost exclusively on this continent. My Machinery's Handbook lists
about six gauge systems, none of them even close to each other. On top
of that, sometimes number drill sizes are used, where a drill of about
1/8" is a number 30. All these systems were developed independently
before there was easy and universal communication between countries,
like languages, and can have vastly different meanings.
Metric is taking over. Get used to it. I still think in
Imperial, but can see the huge advantages of the metric system. Makes
mental arithmetic so much easier.
When metric was forced on Canadians the government told us how
much easier it would be to price food at the supermarket. Now we have
food priced at so much per 100 grams or per 125 grams or whatever
the supermarket managers selects for that week. Nothing has changed.
It is no easier. And don't forget that anything measured by time still must
multiplied or divided by sixty and then by 12.
But when you're building something everything is in units of 10
instead of 12 and 36 and 1/8 and 1/16. A liter of water weighs exactly
a kilogram, and other metric units all line up the same way. Zero is
freezing, 100 is boiling. Believe me, for the engineer it's a dream to
If the supermarket manager wants to mess with the shoppers'
minds, they need to shop elsewhere.
Most engineers I have worked with are proficient in either Metric or
Imperial units, but if pushed will say they find Imperial more versatile and
prefer those units. Mind you, I am an old fogey as are most of the people I
have worked with.
I find it sad that my youngest son has no comprehension of what an eigth of
an inch is - he was taught in school when only metric units were used. I had
the good fortune to be taught both systems from a very early age.
I'm an old fogey, too, and still use the Imperial, but it's out of
force of habit more than anything. The metric system works well for the
young folks in Canada, and us old guys have to make a major mindset
adjustment to avoid translating everything we hear or read in metric
into Imperial so we have some frame of reference. It's not easy. When
I'm driving, I still convert kilometers to miles so I can figure the
ETA more easily. 100 km/h is a common speed limit, and is about 62 mph,
or close enough to a mile a minute. If there are 87 km to the
destination, I take 1/2 of that plus 10 percent (43 + 9) to get 52
miles, or 52 minutes if I'm behaving myself. Somewhat easier than
figuring 87 percent of an hour, for me, anyway. Of course, the young
guy would say 90 percent would be close, and 90 percent of an hour is
54 minutes (.9 x 60, or the same as 9 x 6). *IF* the young guy could do
mental arithmetic, which most can't.

Agreed. I remember trying to teach mathematics to 11 year olds. I was
horrified to find that the Syllabus put more emphasis on using calculators
than teaching the basics of addition, subtraction, multiplication and
division and when I suggested that basic multiplication tables ought to be
learned, there was uproar - from teachers in the Maths department.
I still usually do my sums in my head - after all the batteries never run
I don't know what you are engineering, but by and large the bulk of
electronics is concerned with and measured in seconds or metric subsets of a
second (milli,micro,nano...). The logic can all be expressed in terms of
seconds and only converted to minutes or whatever when it is displayed to a
user, otherwise it is being done the hard way.
Hmmmm, Google ME (metric Edition) server was down when I wrote my
