The metric system vs. the imperial system...

:winkwink:

Metric FTW!

Metric if you want the real measurement of anything...imperial if you are fucking good at fractions.

Haha good one :)

The metric system was a scam to get me to purchase more wrenches.

Ridiculous not to switch why it was proven superior - easier, less time to calculate that would just benefit the society and economy. It looks like the only thing holding them down is famous American pride, how can something be better than their way :)

Anyone know the metric measure of a standard two-by-four wall stud?

That's right...who the fuck cares. It'll always be called a two-by-four. Just like a four-by-eight sheet of plywood.

Metric is just superior

Its just too much fun see in all of you go apeshit, kind of like the Mac vs Pc discussions.:1orglaugh:1orglaugh

Metric was a great way for the oil companies to really bend us over at the pumps. Back when Canada was imperial measure (pre-1981), we had price fluctuations of a few cents a gallon from station to station.

Now, we have those same price fluctuations based per litre...and people don't really stop to think how radical the price differences are per gallon.

you mean that PCs are superior and you just keep cheering for Apple cause it annoys people?

:winkwink:

the avogadro constant is actually defined using carbon and not hydrogen

one upside of non-metric units is that you can pick units that make sense to application at hand...

good example might be measuring blood pressure... no one ever measures blood pressure in SI units (Pascals) cause the numbers would be difficult to work with, everyone uses a made up unit, mmhg instead...

Not sure if serious. If not, ignore my post:

If price per gallon would increase by 1 cent than price per literwould increase roughly 0.25 cent. So 1 liter goes 1 cent more expensive when price per gallon gets 4 cents more expensive.

To think that it goes 4 fold is just ridiculous assumption based on paranoia :)

According to this logic you should advocate selling gas by tons, if 1 liter goes up by 1 cent, 1 ton also goes up by only 1 cent :1orglaugh :1orglaugh

That number is also metric system number, maybe you heard it- millimeters :1orglaugh

mmhg- a simple explanation is in order:

The torr (symbol: Torr) or millimeter of mercury (mmHg) is a non-SI unit of pressure. It is the atmospheric pressure that supports a column of mercury 1 millimeter high.

If your assignment is using mm to represent the height of mercury columns then 1 mm = 1 Torr.

Is it possible that there is another meaning assigned to the mm units in the question?

Is any other info given which might explain such a different interpretation?

From your further info it looks like you have to calculate the difference in pressure represented by each column of mercury from the given atmospheric pressure of 640Torr or 640 mmHg.

Try adding each value in mm to the atmospheric pressure (640 mmHg) to find the total pressure of each gas as each will have to exert a pressure of atmospheric + to produce a reading on the manometer.

we're not seriously discussing blood pressure here, right?

this was obviously about feet, inch, yards, pounds, ...

Funny but its not the "American system" its the UK system which we have kept.

50x100. Need anything else?

P.S it's four-by-two

A lot of countries have inherited the UK system but they have all switched to metric except the U.S. Why ???

Gotta tell ya, for the past 30 years I've been doing recipes in the Imperial system and after about one month in Malaysia, I've converted everything to metric and never looked back.

In the UK though we really like confusing people.
We still use miles for roadsigns, but measure shit in metric.

Anyone over the age of about 50 doesn't do metric, younger than 30 can't do imperial.

When its hot we go fahrenheit, when cold we switch to celsius. (not sure where the switch point is though.)

Peoples weight is measures in stones and height in feet.

because USA is all about tradition :1orglaugh

haha thats awesome :D

so true, UK is a wired mix between the two systems, sometimes it can be confusing.
Imagine, you know that the speed limit on a motorway is 90mph and the distance to your destination is 100km, now go calculate how long is it going to take.

That's why their rockets can't fly :2 cents:

mmhg is derived from a metric unit, but it's not a metric unit, it's a made up unit... metric unit for pressure is pascals...

It's by far the worst here. In canada we have officially adapted to the metric system except border cities, like the one I am in and old timers who refuse to learn the new stick with imperial--which makes things confusing as hell. I grew up around Toronto and temperature is ALL in celsius, out here? nobody knows what i'm talking about, despite learning metric in school. Almost nobody in the country knows their height or weight in metric even though it's on our drivers license that way. Nobody knows how many km' they can throw a baseball or shoot a puck, despite all our vehicles are set to km/h on our spedometers. All the cars built, except from asian companies, are made with imperial. We made the change in 1981. 33 years and we still can't make a decision.


rockets powered by your engines that blew up on you just the same not long ago you mean?

SHAME FAIL

For easy math, let's say prices would go up ten cents per gallon back in the day.

Now they commonly go up 10-cents per litre (there are 3.79 litres to an imperial gallon).

Do the math - that's a 37.9 cent increase per gallon.

People don't stop to comprehend that a 10-cent increase (per litre) is a far greater increase per gallon than prior to the metric conversion in 1981.

All thanks to the French Revolution

his economy is about to blow up also, we can take pride in being a part of that. :thumbsup

do you know the Imperial measurement of a standard 2" X 4"? because it isn't 2" X 4". The term 2" X 4" is a nominal term.

a standard 2" X 4" is actually 1.5" X 3.5". In Canada, and I assume in other countries where the metric system is used, the labels report both Metric and Imperial, the Imperial measurement on the labels is incorrect and states 2" X 4" (The nominal size). The Metric measurement on the label states 38 MM X 79 MM which is correct and is the exact size.

Having worked in the building trade off and on for decades, yes, I know the actual measurement of a standard two-by-four. Nothwithstanding...my 128 yr. old house is built with actual 2x4" (and 2x6" joists) dimensional oak timber. :)

But you can certainly use "Hand me that 38mm by 79mm, would ya..." in a building supply store or on the jobsite...see how that goes for you. For additional fun, don't forget to convert a standard 3 1/2" ardox nail to metric before you ask for a few pounds (not kilograms) of those, too.

Canada began switching to metric when I was in elementary school - I still think in imperial measures. A hot day to me will always be 90 degrees. It makes more sense to me that a 100 degree day is extremely hot and a 0 degree day is extremely cold.

What does McDonalds call the Quarter Pounder in other parts of the world?

That's why your nuclear power plants meltdown. :2 cents:

McDog in Korea.

Hamburger Royal

that's because it's all written on the side of the measuring cup! :1orglaugh

Petrol prices are not influenced by gallons or litres :2 cents:

Universal price is per barrel and that filters down to the petrol stations.....

Idiotic. What does that clip even mean? Americans can't relate? The watch face makes more sense... can't even read the rest. Dumb.

Mine? I'm not an Ukrainian :winkwink:

What did you expect from experimental engines (never used on real Soviet/Russian rockets) made in the USSR (Soviet Ukrainian Republic) 40 years ago? Not just designed but physically made :1orglaugh

90-60-90 -- WTF is that? a Buffalo Girl?

Joe I need 6 /2 meter 100x50's Joe: OK, I'll ask the crane operator to send them up ...

Do you have size 44 shoes in this style -- WTF Willis? :1orglaugh

We Americans don't buy gasoline in 1 liter Coke bottles (except for a riot) :P

That said, it's metric sized when we export it ... A lot of engineering and scientific measurement/dimensions are in metric.

BTW, Imperial measure FYI refers to the UK and Canada, not the USA. We don't have kings or nobility ...

ussr/soviet/russian/ukranian.... sorry, those shell games you got going there don't have anyone fooled. they all had the same leaders and scientists support at the time...

The americans have admitted to their ongoing problems with their space program, it is you and your country that is in denial still.

That being said the world needs both your countries in the steps moving forward, no doubt. I hope we live long enough to see it in our lifetimes.

We have a nice mixture of both here in the good old USA... Its ALWAYS been a mixture of metric/inches wrenches when you work on any car or motorcycle here... and on some cars with the digital dash for fun you can always hit the switch from MPH to KMH when your buddies aint looking and say "damn... look how smooth the rides going over 100"

We buy our milk and gas by the gallon and our Cokes by the liter...

But one form of measurement will NEVER change... when your wanting absolute precise zero tolerance NASA approved perfection... the RED CUNT HAIR is the WORLD standard!!! :thumbsup

We have Quarter Pounder. As McChicken or McFeast or Filet-O-Fish. Only some are translated to our language as the name can be abstract as well, and we can speak English too, if that matters.

Problems with what? Soviet Union/Russia has launched more rockets than all countries together and no one cosmonaut has died because the unsuccessful rocket launch. NO ONE.
