[USMA:29661] RE: NASA Cassini
Terry, You realize that JPL has the highest degree of metrication of any NASA department. The biggest problem with NASA is that there is a mix of systems to varying degrees. On the pure science side, they are predominately to exclusively SI. On the engineering side, there is more non-metric used but SI is making inroads. Of course legacy systems like the space shuttle are 100% non-metric and are probably not going to change. As NASA is dependent on the private engineering sector for its projects, they need to make some changes to the culture and convince contractors of the benefits of moving projects to SI. This involves getting over the old fogey factor with senior engineers who are not willing to leave their comfort zones. What we need to do is convince NASA that the extra short-term cost of pushing metrication is well worth the long-term gain and that the investment will pay off many fold. The interesting thing is that many (on this list and other places) like to blame NASA for the Mars Orbiter fiasco. Remember, NASA was the one using metric while the contractor did not.

[USMA:29662] Metric discussion regarding railroads - long but perhaps interesting
Looks like I started something on a railroad-oriented list. Someone said that a "half-mile long" passenger train was the longest he had seen. Then he described a 70-car train. I pointed out how long it was - and away things went; it got rather interesting.This is rather long and if you don't want to read it this is a good time to click delete. But it shows that consideration of metric goes well beyond our own group, and is an underlying current in the general population. Despite what the whiners would have us believe, there is more support for conversion that one would think.The moderators of this railroad list let things stray a bit if they seem to be interesting.CarletonI started out with:"A passenger car averages 25 m long. 25 x 70 = 1750 m. One mile is1609.344 m, so a 70-car train would be considerably longer." Marty answered:Please recall that when you look out your office window, you are lookingat the USA and the USA uses a different set of measurements thensomething known as "m.". Regardless what you think of thosemeasurements that the USA uses,, they still are the standard for thiscountry and should be used.From the above note I gather that a 70 car trains is longer then a milebut the other numbers mean absolutely nothing to me.MartySomeone else responded with a rhyme:"A yard is a meterA quart is a liter."And Marty said:NO, in this country a yard is 3 feeta quart is 2 pintsIf you want to play with meter and liter's go to Canada or almostanywhere else but this not anywhere else this is here and I don't carewhat the world does, I don't care how many people think our system isarchaic, old fashion, out of touch with the world (similar to a reporterusing "chugging" to describe an Amtrak train) etc, the fact remains thatit is our system and it hasn't been changed (not without trying, butstill not changed).4 feet 8 1/2 inches is still the gauge not some other mucky muck numberI'm 63, and while you can teach old dogs new tricks, many times old dogsdon't want to learn new tricks when it is not necessary. And at thispoint in time and space it is not necessary.MartyAnd the response from Vancouver, BC:Well, I'm sorry you feel that way about the measurement systems, but donote that there are members from all over the world on this list, plusmany others from the US that *DO* understand metric measurements. Ifyou don't want to learn metric, then feel free to skip the post.Personally, I'm fine with the metric system, and don't think "I don'twanna learn" is a valid reason not to make certain changes.RobertVancouver, BCTo which Tony from Australia responded:Marty,Just remind me -Are those miles of yours -StatuteRomanRussianSwedishIrishNautical?And then Merritt from the USA chimed in:Actually, regardless of what you think, the metric system is a standardfor this county (the USA, that is--I don't know where the originalposters office is and what he sees when he looks out the window). Itmay not be used as much by the average person as the "English" system,but is is a legal standard, and all our "English" measurements arebased on it, not the other way around. From the above note I gather that a 70 car trains is longer then a mile but the other numbers mean absolutely nothing to me.From the above, I take it you went to school many many years ago, oryou wouldn't be saying that.MerrittMerritt had more to say:On Tuesday, April 27, 2004, at 01:25 PM, Marty wrote: "A yard is a meter A quart is a liter." NO, in this country a yard is 3 feet a quart is 2 pintsBut legally, they aren't. In the USA, a yard is 0.9144 meters, and aquart is 0.946 liters. USA customary measures are defined by thegovernment (Bureau of Standards) in terms of metric measurements. If you want to play with meter and liter's go to Canada or almost anywhere else but this not anywhere else this is here and I don't care what the world does, I don't care how many people think our system is archaic, old fashion, out of touch with the world (similar to a reporter using "chugging" to describe an Amtrak train) etc, the fact remains that it is our system and it hasn't been changed (not without trying, but still not changed).It is not really "our" system, it is the English system (with somemodifications). And it was changed by us to be based on the metricstandards. What hasn't changed much is our everyday usage. 4 feet 8 1/2 inches is still the gauge not some other mucky muck number4 feet 8.5 inches and 1435 mm are the same distance and both are"standard" gauge. I'm 63, and while you can teach old dogs new tricks, many times old dogs don't want to learn new tricks when it is not necessary. And at this point in time and space it is not necessary.It is one thing to have a preference for using one system over theother (obviously, most Americans prefer the customary system), but thatdoesn't call for complaining when someone else uses the other system.I am 69 years old, have always lived in

I know a lot of industry in the states are already there, however a lot of state departments of transportations have gone back to imperial measurements. I doubt if they will ever go back to metric, what do you think? Probably a lot of Americans don't even realize that the metric system has been legal in the States since Jul. 28 1866.

Euric http://www.unc.edu/~rowlett/units/ "What countries besides the U.S. have not adopted the metric system?"This question comes from U.S. students, who've been assigned by their teachers to find out. Many of the teachers think the answer is "Liberia and Burma" (make that Myanmar). Let's give Liberia and Myanmar a break! All countries have adopted the metric system, and most countries (if not the U.S.) have taken steps to eliminate most uses of traditional measurements. However, in all countries people still use traditional units sometimes, at least in colloquial expressions. Becoming metric is not a one-time event that has either happened or not. It is a process that happens over time. Every country is somewhere in this process of going metric, some much further along than others, but no country should forget its traditional units completely. At least, that's the philosophy of this dictionary!

Without waiting for Paul to respond (remember, we all get to speak here g), I'll say that I'm confident that the U.S. will eventually be totally metric (with the possible exception of some really pervasive legacy stuff, such as tire and wheel diameters, socket-wrench drivers, etc.). However, given that I'm on the dark side of 68, I don't believe it will be in my lifetime. As I plan to be shot in bed by a jealous husband when I'm 99, that means I don't see it happening within the next three decades. I hope I'm wrong. And, of course, I believe we'll be well ahead of where we are now. It's a pity Joe Reid didn't live to see the mess in Canada cleaned up.

Carleton, sir: A passenger car averages 25 m long. 25 x 70 = 1750 m. One mile is 1609.344 m, so a 70-car train would be considerably longer. The failure of metric reform! You talk of the 'confusion' in the same breath - metre and mile. Instead you could simply say: If, a passenger car averages 25 m long. 40 cars would be ONE kilometre (25 x 40 = 1000 m).

And make the calendar work with Leap Week Rule! * * * * From: Carleton MacDonald [EMAIL PROTECTED] Reply-To: [EMAIL PROTECTED] To: U.S. Metric Association [EMAIL PROTECTED] Subject: [USMA:29662] Metric discussion regarding railroads - long but perhaps interesting Date: Mon, 3 May 2004 10:52:00 -0400 Looks like I started something on a railroad-oriented list. Someone said that a half-mile long passenger train was the longest he had seen. Then he described a 70-car train. I pointed out how long it was - and away things went; it got rather interesting. This is rather long and if you don't want to read it this is a good time to click delete. But it shows that consideration of metric goes well beyond our own group, and is an underlying current in the general population. Despite what the whiners would have us believe, there is more support for conversion that one would think. The moderators of this railroad list let things stray a bit if they seem to be interesting. Carleton I started out with: A passenger car averages 25 m long. 25 x 70 = 1750 m. One mile is 1609.344 m, so a 70-car train would be considerably longer. Marty answered: Please recall that when you look out your office window, you are looking at the USA and the USA uses a different set of measurements then something known as m.. Regardless what you think of those measurements that the USA uses,, they still are the standard for this country and should be used. From the above note I gather that a 70 car trains is longer then a mile but the other numbers mean absolutely nothing to me. Marty Someone else responded with a rhyme: A yard is a meter A quart is a liter. And Marty said: NO, in this country a yard is 3 feet a quart is 2 pints If you want to play with meter and liter's go to Canada or almost anywhere else but this not anywhere else this is here and I don't care what the world does, I don't care how many people think our system is archaic, old fashion, out of touch with the world (similar to a reporter using chugging to describe an Amtrak train) etc, the fact remains that it is our system and it hasn't been changed (not without trying, but still not changed). 4 feet 8 1/2 inches is still the gauge not some other mucky muck number I'm 63, and while you can teach old dogs new tricks, many times old dogs don't want to learn new tricks when it is not necessary. And at this point in time and space it is not necessary. Marty And the response from Vancouver, BC: Well, I'm sorry you feel that way about the measurement systems, but do note that there are members from all over the world on this list, plus many others from the US that *DO* understand metric measurements. If you don't want to learn metric, then feel free to skip the post. Personally, I'm fine with the metric system, and don't think I don't wanna learn is a valid reason not to make certain changes. Robert Vancouver, BC To which Tony from Australia responded: Marty, Just remind me - Are those miles of yours - Statute Roman Russian Swedish Irish Nautical? And then Merritt from the USA chimed in: Actually, regardless of what you think, the metric system is a standard for this county (the USA, that is--I don't know where the original posters office is and what he sees when he looks out the window). It may not be used as much by the average person as the English system, but is is a legal standard, and all our English measurements are based on it, not the other way around. From the above note I gather that a 70 car trains is longer then a mile but the other numbers mean absolutely nothing to me. From the above, I take it you went to school many many years ago, or you wouldn't be saying that.
