Wake up and smell the coffee! It isn't going to happen, for several reasons, including 1. Your research skills are better than those of most others following this thread, and 2. You are better able to distinguish "swallow's tongue" conversion factors from official definitions, and 3. They don't have a reputation to reconstruct, and 4. They don't know people at NIST that they can call on for help in this search for the official definition, and 5. You've got them all convinced that you are an expert in this area, and everyone expects that you could easily prove your point, and 6. A lot of people who know more about this than you do have unsucessfully searched for an official definition, and 7. Dr. Barry Taylor, the NIST expert in this particular field who must be a METROLOGIST if you are a mere capital-M Metrologist, is the one who gives us the conditional definition which is a clear indicator that an official definition does not exist. Face the facts. Hard as it might be to believe (even for me, when I first came to this realization!), THERE IS NO SUCH OFFICIAL DEFINITION OF A POUND FORCE. Nobody has ever gone to the trouble of officially defining these ******* offspring of pounds as units of mass, and nobody will bother doing so in the future.

wrote: Wake up and smell the coffee! Hi Gene, You've missed one point (beyond I am not a coffee drinker) to which I can respond: I don't give a damn. :-) Your condescending attitude towards others all convinced that you are an expert is obviously spun from your imagination as absolutely no one here has commented for me, with me, to me, or about me (your QRM hardly allows them that). As for reputation.... You, admittedly, have absolutely no experience in the matter, and this is not rec.sci.amateur.hour. Given your petulance out of the gate discussing the subject, you don't even qualify for honorary troll. You have no style, and the cut-and-paste philosophy runs thick in this group as it is. Yours certainly is no more distinctive, and when it is laid out by the ream like so much textual fertilizer, it won't grow the crops to save the farm. C'mon now Gene, we both know what I have to say on the matter is wholly irrelevant to how you are going to boast about it around town. Sort of like the tailor who wore on his belt "Killed seven with one blow" and was only boasting about flies while gushing it up about giants. Talk about (emphasis on talk) reputations made. ;-) 73's Richard Clark, KB7QHC |

I live in one of the windiest parts of the country, and I am quite capable of recognizing the sound of hot air rushing by. If there is, in fact, an official definition of the pound as a unit of force, it isn't going to be a closely guarded secret, even post-11 Sep 2001. If you are a Metrologist, it should be a piece of cake to find it. So for you, or anyone else who would like to help you out, here are a few hints. Some of you likely are or have been science teachers. Use the resources you have at hand to find this elusive official definition of the pound as a unit of force. Tell me exactly what the standard is, who defined it, and when. Or go to someone you had as a science teacher, and enlist their help. Go to a science teacher who is teaching your kids or grandkids. Look in the textbooks you used, and see if the authors have any footnotes citing the authority for whatever definition they use. Look for the official definition in the CRC Handbook of Chemistry and Physics, or in the Engineer's Handbook. Look for the official definition in Encyclopædia Britannica, or in World Book Encyclopedia, or the World Almanac, and whatever source is cited in any of these. Write or email NIST, and be sure to ask them not only what the official definition is, but what makes it official and how long it has been in use.

More possibilities-- Go to sci.physics or slug.support and ask the people there to point you to the official definition of the pound as a unit of force. Search Lexis (http://www.lexis-nexis.com) for a legal definition, if you are a subscriber to this service or know someone who has access to it.

Tell me exactly what the standard is, who defined it, and when. I'm not a science teacher, but it wasn't hard to find. Look in the _Handbook of Mathematical Functions_ under "Physical Constants and Conversion Factors," by A.G. McNish of the National Bureau of Standards (this is an old book). There it is, clear as a drunkard's gin, 1 pound force = 4.44822 Newtons. Speaking of Newtons, Newton, is the catty a unit of weight, force, or mass, and where is the official definition of same? What! No official definition of a unit that has been in use for thousands of years? Why are you arguing about old measurement standards on a newsgroup that is supposed to be devoted to the amateur use of antennas? There should be a newsgroup devoted to the obsessions of amateur physicists where like-minded people could rail at one another without bothering anyone else. You should understand that there are very few people in the world who ever bother to let the concept of pound force disturb their sleep at night. Perhaps you shouldn't let it bother yours, either. 73, Tom Donaly, KA6RUH |

McNish of the National Bureau of Standards (this is an old book). There it is, clear as a drunkard's gin, 1 pound force = 4.44822 Newtons. Speaking of Newtons, How old? When was it published (before or after 1959, in particular). I will bet that Richard Clark won't endorse your finding as being any sort of "official definition." What do you say, Richard? Did he find a hidden treasure? McNish also gives a conversion factor for pounds to kilograms, doesn't he? From what you have given us, he identified the "pounds force" as such. What does he call the pounds which are converted to kilograms? Just "pounds"? Or "pounds mass"? Or just "pounds avoirdupois" and "pounds troy" without saying that they are pounds mass? I'll also bet that McNish didn't call them "Newtons"--it is newtons, not capitalized in English. Now, let's assume that this were an official definition. Then what is the "standard acceleration of gravity" in English units? A pound force is equal to a pound mass times the standard acceleration of gravity. We already know a pound is officially defined as 0.45359237 kg, so that standard acceleration of gravity will be 1 lbf divided by 1 lb. 1 lbf/1 lb =4.44822 N/0.45359237 kg = (4.44822 kg m/s²)/0.45359237 kg = 4.44822/0.45359237 m/s² or about 9.80664643896 m/s² (4.44822/0.45359237 m/s²)(1 ft/0.3048 m) = 4.44822/0.138254954376 ft/s² = 32.17403687... ft/s² That is indeed awfully close to the standard acceleration of free fall which is official for defining kilograms force. But it isn't the same, if that is an official definition of a pound force. Gene wrote, Newton, is the catty a unit of weight, force, or mass, and where is the official definition of same? What! No official definition of a unit that has been in use for thousands of years? There are lots of official definitions--but since I don't read Chinese, I'm not about to venture a guess as to whether or not any of them are found on the Internet. They are units of mass, of course. Originally represented by independently maintained standards, and varying somewhat in different countries. Just as pounds were and just as kilograms still are. But at various times and places, and for various purposes such as international trade, catties were officially redefined in several different ways: as exactly 1 1/3 lb avoirdupois, as exactly 600 g, and as exactly 500 g are just a few of those official redefinitions--there might also have been one in terms of troy units, perhaps 20 oz troy = 1 2/3 lb troy, and perhaps other redefinitions in terms of either Spanish or Portuguese libras. Gene Nygaard http://ourworld.compuserve.com/homepages/Gene_Nygaard/ That's the kind of reply I expected. You didn't reply, however, to my contention that your posts are off topic and excessively obsessive. I'd like to know something, though. What made you believe that anyone here would be interested in your petty distinction between pounds and pounds? I expect Richard is enjoying himself, as he collects much laughter up the sleeve, but I think the whole thing is strange, even for this newsgroup. 73, Tom Donaly, KA6RUH |
