Re: Convenience of the metric system

having preferences is fine, to a point. and moving that point right or left to divide or multiply by ten is easier with metric.

And who really cares how much volume the beer stein or rhum glass holds? You will still always reach for 'the big one'.

Before that it was the length of a bar kept somewhere in Paris.
Before that they indeed took 1/10000000 of the distance from the equator to the pole, because that ended up a good size, about the length of a pace...
Incidentally the nautical mile is defined in a similar way, as the length of one arc minute measured on the equator. This gives all kinds of advantages when doing astronomical navigation. For the same reason surveyors in metric countries will measure angles in "gon", of which 400 go in a circle...

Re: Convenience of the metric system

Some interesting conversions:
1 million microphones = 1 megaphone
1 million bicycles = 2 megacycles
2000 mockingbirds = 2 kilomockingbirds
10 cards = 1 decacards (or is it 52 cards = 1 deck-a-cards?)
1/2 lavatory = 1 demijohn
1 millionth of a fish = 1 microfiche
453.6 graham crackers = 1 pound cake
10 rations = 1 decoration
10 millipedes = 1 centipede
3-1/3 tridents = 1 decadent
10 monologs = 5 dialogues
2 monograms = 1 diagram
8 nickles = 2 paradigms
2 wharves = 1 paradox

The carriage makers of course had been sizing their carriages to work on the roads that existed in England prior to the railways. The dimension for the ruts in the roads from which the carriage makers built the new railways was of coarse based on the carriages the Romans had used when the roads were first made.

So basically a key design constraint for the space shuttle was the wheel width of a Roman cart.
Nice story. But factually wrong. The railway track gauge has nothing to do with the romans, but everything with Stephenson starting with a nice round number...
And the loading gauge is another different matter. That is a lot larger then the one used in the UK... (In the US everything is larger after all...)

But we do have something between m and cm : dm. The decimeter. Not used a lot as most people do fine with just m and cm, or m and mm.

Exfcellent Gord!

At some point I did the mental math of the use converting to the metric system in terms of road signage.

There are about 4 million miles of roads in the US. England OTOH has about 250,000 miles.

Not a small undertaking to convert.

Well, actually I don't. I'm not a gun guy and am about the only one in Montana!

I was talking to my hunting guide friend about bullet size a while back. I had the millimeters figured out but never thought about the caliber size. I asked him if it was based on something and he said it was totally random measurement. It took me less than a minute to find out it was based on 100ths of an inch thanks to Mr. Google. So here we have a hunting guide that has probably shot 10s of thousands of bullets that has no clue what a bullet size comes from. Think about that!

And let's not forget the metric unit every sailor should know - the millihelen.

Re: Convenience of the metric system

yeah, they're the ones with pockets sewn onto the chests of their shirts, and they are the only one who say "Hi".

But don't confuse those with Texans. Or kid yourselves that we can't spot an European in about ten seconds.

And that's one of the tougher ones.... Less for the typical haircut, dress, sandals, etc... Avg... 3 seconds???

Re: Convenience of the metric system

I like the metric system especially in attitudes.........
Like with shoes you get a better fit or closer to what you need in an attitude..
The local store on the corner , (7-11 in the US) sells attitudes, but they only come in full sizes , so when buying one, its either to Damn tight or it to Friggin Big..
And even thou they carry metric size attitudes, you never want to buy one from a second hand store , as its probably because the origional owner either broke it or it didnt fit proper..
And last, dont go to Wal-mart, or K-Mart, to buy your attitudes, even thou they carry a large asortment at discount prices, you NEVER know who had it on befor you..
And thats why I like the metric system............................................ ............

Re: Convenience of the metric system

What I know so do the whole world (even US) use 10 as the base in mathematic, so I donít think its possible to change. 16 would have been much better.

If I read that a boat have a weight of 7000 lb, I think itís the half in kilo or 3500 kg. That way I get a hum of the weight thatís near enough.
They have a 35 lb anchor. The half is 17.5 but if I want it more exact I subtract 10% or 1.75 and get 17.5 Ė 1.75 and thatís around 16 kilo.
The boat has 80 gallons of water. I take the double 160 and then the double agene 320 liter. (I know itís wrong, but I think it should be spelled that way).

I notice that itís not only me that donít know how many yards there is on one mile.

Some imperial headed person, can you calculate the efficiency of the windlass? I believe itís quite complicated even if itís only to multiply the force with the speed, but what unit do you get?
Motor power 0.9 hp.
Working load 250 lb.
Chain speed 65 ft/min.

Texas...phfft.

Compared to Alberta,they have smaller ranches, less cattle, less oil, and our women are much prettier.
