GENIAL !!, Muchas GRACIAS por su forma tan didactica y clara de explicar las cosas..Saludos desde San Luis, Argentina. Intente usar el sistema No Metrico y me resulto muy dificil. Pero Parece !! muy Practico. 🙂
I seem to remember seeing something in a magazine when I was a kid where speed signs in the US were both in miles and kilometres...so close to becoming part of the rest of the world for measures. The two litre bottle example for soft drink is a good example of how an industry has gone metric however that seems to fall apart if I buy a can of the very same drink from the same manufacturer. *sigh* How lucky I am to live in a country where there is only metric.
Yes, you are lucky. Back in the 1970s there were some conversions to metric on road signs, but not many. Not far from where I live, there was one sign on Interstate 90 that had the distance to the next exit in km. That was the only one I know of in upstate NY. A few years back they replaced it with one in miles. We've gone backwards.
@@ElectronicswithProfessorFiore Lucky to an extent. The thing that still hurts is Milli, e.g. 300 millilitres is commonly shortened to 300 mills =0.3 litres or 300 millimetres is commonly shortened to 300 mills = 0.3 of a metre. So we pronounce it as mills or mills...they both sound the same. Now for through hole components this is evil as a standard DIP is 300 mils which not equal to 300 mills. Begs the question, why do this? Why are electronic measures that are imperial expressed as mils instead of something like 300 thou which _infers_ that we are talking inches instead of using SI units?
@@martinkalitis5500 In the USA, a "mil" is one one-thousandth of an inch, which is an order of magnitude smaller than a millimeter. It's just more evidence that we're crazy. At least some of us, anyway. Excuse the soapbox, but when most current adult USAians went to school, they were told that this is the greatest country in the world that ever was, is, and will be; that everything we do and have is the best there is; and that everyone else in the world wants to live here because of this. I remember this drumbeat well having been a kid in the 60s. It may even have been true to an extent in the decades following WW2 (having been the only major industrial nation that hadn't seen its cities bombed into rubble). When you believe that, then you become resistant to anything that comes from outside. It's all seen as somehow inferior, with evidence to the contrary ignored. Over time the disconnect makes you fall behind and wind up doing (and defending) some very dumb things. I used to be competitive distance runner and one of my sayings was that the easiest way to fall from the top position was to continually remind yourself that you're the best.
I subbed to you when you started about the communist conspiracy stuf. I like your style, you explain complicated stuff in a nice and easy way with the right touch of humor and that's a rare combination to stumble uppon here on UA-cam.
The strangest thing about this: the USA signed the metric convention. And this was not just yesterday. It was in 1875. You have 2 of the 40 1 kg prototypes in your county - since 1875. You used the former British system, but you declared independence of Great Britain - in 1776. GB use the SI system since a long time ago. You stayed with the old British. Isn't it crazy? But the metric system has also a problem, and it is unfortunately of all things with the mass. The mass is measured in Kilograms. Why kilo? Where is the problem with defining the old Kilogram to the new Gram? So you cannot simply use kkg for 1000 kg or mkg for gram. This kilo is a pain in the ass for me.
It has to do with internal consistency. Look up the difference between MKS (meter-kilogram-second) and CGS (centimeter-gram-second) systems. But that's a minor issue. The fact that the average USAian refuses to use a system that is far easier to use and which the rest of the world uses is the main problem. I believe it says something about our shortsightedness and provincialism.
It's just another bit of stupid here in the USA. People don't give their height in total inches, either. i.e., 72 inches instead of 6 feet. I don't understand why people cling to a clumsy, outmoded system when there is a much better one available. Mental inertia, I guess, and maybe a fear of the new, coupled with short-sighted corporate/Wall Street interests who will not invest today to make tomorrow better.
3:01......." a lot of people believe crazy things"....😂... you are a.k.a. "professor" and catching tiniest opportunity, emphasizing that statement...so do video on "crazy thing people believe" and see that will happen to your channel......😂😂

Good Day Professor Fiore. I'm an engineering student from Asia and I've been watching your videos and I've learned a lot. Thank you so much.
Happy to be of service. Take care.
