They also left out Chinese HP, where you measure the max input power to the motor while ignoring the output.Quote:

Hi Gang:
Why O Why do they teach Metric as conversions from Imperial? The true confusion is converting any Imperial unit to anything else! I mostly use metric in my shop resisting the urge to use inches since metric is so much easier to deal with. I really decided metric is cool when I realized a cubic meter of water weighs a metric tonne! Here is a video that explains it all:
https://www.google.com/search?q=snl+...qfVE-fykk,st:0
Best wishes, Carl.
Well said Carl. From your example a cubic metre of water contains 1,000 litres and it follows that one litre of water weighs one kilogram, a millilitre weighs one gramme etc.
It's all so easy using the metric system, with a divisor between like units of one thousand. Eg 1,000 mm = metre, 1,000 metres = one kilometre etc.
I'm still confused as to why in the US large units of measurement are not converted into more manageable units for example a dozer weighs 100,000 lbs, that's incomprehensible. Why don't you guys say 50 tons ?, or whatever the conversion is.
According to Google, only three countries in the world use the Imperial system of measurement, Liberia, Myanmar and the US. What does that tell you?
Hello Bony:
My theory is news reporters pick the units to empathize the direction they are taking with the story. If they want BIG, they pick units that express the units with a number from 6 to 9, and with as many zeros as possible. If they want to make sound small, a from 1 to 4. Most folks can't make change for a nickle so they go with their gut feeling about numbers. And to use the Metric system correctly you should never use a numerator over 999, just use the proper prefix: Say megameter, 1 Mm, not 1000 km.
Carl.
The US doesn't use the Imperial system. They use a system termed the 'US customary units'. The US system is based on the Imperial system and shares some units with it but some units differ and units that are not in the Imperial system are included.Quote:

The fact that so many disparate cultures have adopted the intelligently designed metric system is testimony to the need for simplification. Face it - if you can get the Germans and the Italians to agree to use a system designed by the French, it must be good.
I agree wholeheartedly Marv, so what would it take to introduce the metric system, or does politics prevent any hope of that? I would like to think that common sense would prevail.
We managed it in Australia in 1972, mind you we also had pounds, shillings and pence as currency, and that would have been sufficient catalyst on its own!
I won't comment on the political angle. Politics and religion usually lead to off-topic, generally vituperative, flame wars that have no place on engineering fora.Quote:

I spent 35 of those years teaching "shop class" know as Industrial Arts, which morphed into Industrial Technology, then just Technology as the public grew weary of anything "Industrial". I began teaching in 1974. There was a big push to go metric around that time. That fizzled.Quote:

Early Attempts
1793: Thomas Jefferson proposed evaluating the metric system for the United States.
1866: The Metric Act made the use of metric weights and measures legal, but it was not mandatory.
Significant Legislation
1975: The Metric Conversion Act was signed into law, declaring the metric system as the preferred system for trade and commerce. This act allowed for voluntary conversion to metric units.
Recent Developments
1991: An executive order directed U.S. government agencies to adopt the metric system as the preferred system of weights and measures.
Current Status
Despite these efforts, the conversion to the metric system has faced resistance, and U.S. customary units remain widely used in many sectors.
Full DIsclosure the preceding time line is an AI generated response to "when did the USA try to convert to metric"
In reality the only thing magical about the metric system is the basis for the units and the decimal relationship between them all. There is no argument, it is indeed a well thought out system.
That said, one with thinking skills should be able to work in any system presented. If you do not truly know how to use measurements, does not matter which system, you will still mess it up.
It would be nice if there was only one system, just as it would be nice if we all spoke the same language, but we don't. We can even miss understand people who are using the same language.
Perhaps when the world hits the reset button it will reboot with everyone agreeing on everything. But I am not going to hold my breath. I just work with what I have.
There's more to it than power-of-ten unit relationships. Separate units for mass and force (using different names, no less) and getting rid of units like fluid-ounce that depend on the nature of the substance measured are just two examples.Quote:

Then we need to get into language. That is even more crazy;
to, too, two
red, read, read
led, lead, lead, l.e.d.
The list goes on and on.
A large proportion of the folks on this forum think the opposite of (win, find) is 'loose'.Quote:

On a separate, non-metric note, yesterday I discovered this in a Reuter's news article about a particularly well preserved fossil in Wyoming that included this illustration. When I first saw it, I didn't notice the caption and my first thought was 'Have they made Sam Neill in Jurassic Park as standard measurement??' then I saw the caption. Yes they did...

please let's not get started on the lunacy of the English language. Homophones, homographs, and homonyms, and words which can simultaneously be nouns, pronouns, verbs, and possibly adjectives, sometimes used in multiple forms of context within the structure of a single sentence, are enough to drive a person bonkers.Quote:

I was taught both systems in primary school over 60 years ago in a small-town school here in Texas.
What do you expect from a language that has been described thusly:
Quote:
“The problem with defending the purity of the English language is that English is about as pure as a cribhouse whore. We don't just borrow words; on occasion, English has pursued other languages down alleyways to beat them unconscious and rifle their pockets for new vocabulary.”
― James D. Nicoll
Keeping with the lunacy of language, does this mean you are homophobic? (Sorry, sometimes I can't help myself.)Quote:

Hi Hemmjo:
I would be surprised if it were 0.14 hp or even 1.4 Amp. But the screw spacing on those shaded pole motors is fairly consistent. You might need to swap blades to match your ceiling box.
But new fans are quieter and move more air, so perhaps swapping the box would be worth it??
Good luck, Carl.
I'd buy 5 just for the motor!Quote:

So then does metric phobia mean the individual is not afraid of metric but merely fails to grasp the understanding of the methodQuote:

I wouldn't have thought anything about that had all of the threads needed cleaning up after removing a broken fastener from the holes. but 3 of the holes were pristine and clean. and the new fasteners were proprietary in shape I ordered the proper 5/8-12 tap.
As TM51 once said who knew 12 was an odd number
If you enjoy unusual threads find a Bendix-Stromberg pressure carburetor such as used on a Allison V-1710 engine. 50 parts and all the threads are different and nothing you will find on anything else. And carburetors in general have unique threaded parts so that it is difficult to mix up parts...
Sounds like you either worked on mustangs or have repurposed those engines into racing, or tractor pull vehicles.Quote:

Hi Gang:
A cubic yard of water weights 1,685.6 pounds
A cubic meter of water weights 1000 kg, or a metric tonne
One seems easier to remember.
Carl.
Either way, that is 0.1915 Asian elephants - unless you use African bush elephants, then it is 0.1296 elephants.Quote:

In the end, either system is based on random selection of some standard unit dimension, and it's arbitrary. But we can calculated stuff, in either system. And metric, for most stuff is the easiest to translate, as water is most of what is common experience, to use for relative reference.
