Re: Convenience of the metric system

Metric is great in the classroom because it's base 10 and easy to calculate conversions and factors in our head.

In the workshop I find imperial to be more useful as the divisions are easier to guestimate by eye. Inches and feet compared to cms and meters for example.

Much of the empirical information around clearances and fits is mostly based on imperial and not metric.

Fasteners and the dash (1/16) system for fittings are also imperial.

I don't have a preference. I use a mix of metric and imperial. Best of both worlds. Converting between the two is easy.

Re: Convenience of the metric system

Historically, up to the time the French invented metric, every kingdom and principality had its own based upon deep tradition system of weights and measures. In the late 18th-early 19th century what is now Germany contained about 300 such different systems attached to 300 different principalities and even in unified France each historic region had it's own peculiar differences. Why, 150-200 years after most countries began switching to metric we are still debating the issue is beyond me, regardless of any alleged pluses or minuses of the nonmetric. It is what it is and we better get on with the show or be left behind. Besides, I resent keeping 2 sets of tools as this is a total waste of my $$.

My favourite boat brand (when dreaming) is RM, and they designate their models in metric: RM890, RM1050 etc...
However, when they recently announced their new RM 1070 the press release mentioned that their aim was to build the "best 35 footer on the market".
Go figure...

A 2x4 is the rough unplanned cut size. Planing it gets it to the finished size.

I used to handle those 2x4 in a planing mill back in university in summers. Some old houses still have the full sized dimensions.. in other words, unplaned.

Oops, my bad. I meant to quote Benz. He posted just before yours. I didn't have my coffee yet. Sorry.

I read the Anarchist Cookbook too. You are a bad boy. Me too.

You just got a slight case of the Benz there. Into the evolutionary chamber for a while to straighten you out again.

personally I now can estimate better with metric, and my kids have no idea what an "inch " is !


err- NO. The metric fastener range is the most prolific in the world , as for the dash system ( i.e. BSP pipe). I agree, but thats an accident of history and it has been codified into the metric system. ( its a bit like saying imperial is better cause boat companies , even metric ones quote feet, to them its merely a "designator" of size)

Ahh... But 9mm is much less expensive, and it's metric.

7.62x38R costs lots - all to use a 60yo relic - but it's metric.

So a Mantus anchor is a bolt-together design. Are the bolts SAE or metric?


Figuring 'bout time to throw in something about anchors

Those at this side of the pond are metric - and the smear that comes with the bolts for assembly stinks

Re: Convenience of the metric system

US Army DI, "Be back in a skidit" which I believe = a nanosecond.

My Harley has three metric nuts on it, my BMW m/c had three SAE
nuts on it. Someone care to explain that.

Some folks like McDonald's, some(me) like home style country cooking.
I really like using both SAE, and metric, but I think in SAE then get a little
brain exercise doing the conversions.

I used a micrometer to measure wire that was sold in gauges, and put on 6 inch spools.

Socialist tend to want homogenization, while capitalist make millions playing
the currency market. Watch those conversions !

So is the Euro based on 10's ?

Not totally sure but I believe the US Dollar is.
2 bits 4 bits 6 bits a dollar all for SAE stand up and holler !

I'll take a quarter-pounder with cheese please...

You don't know that. There is no way to tell. It could be anything from the number five in base three upwards.

I have worked in surveying for years and love the engineer's tape, especially now in my weakening eye strength years. I can see the hundreds of a foot easily and guestimate the 5/1000th which is about 1/16 of an inch.

You have to watch the tapes that are marked both in inches and in tenths of a foot. Hand one of those to someone that is not paying attention and you will have a wrong measurement somewhere.
