Oh, I see, the equation T = 1/(2pi RC) works in SI units (and also in Gaussian units). This doesn't change the principal scientific objection, though. Andrew Usher

I mean, 8 fluid ounces make one cup, 16 avoirdupois ounces make 1 avoirdupois pound, and 12 Troy ounces make 1 Troy pound... and, of course, each ounce is quite distinct from the other. It's not like a fluid ounce of water weighs 1 troy ounce or 1 avoirdupois ounce, god forbid. -- Beware of bugs in the above code; I have only proved it correct, not tried it. -- Donald E. Knuth

That's easy to explain historically - the US volume units originate before anyone used the fluid ounce in English. The Imperial units came later and they do have the correct fluid ounce (= 1 oz. av. water). You probably know that I use certain British spellings, and have as long as I have been on the internet. This is intentional as I believe that there should be an international standard spelling for English. Similarly there should be an international standard for English units and it's obvious that this should have Imperial volume units but US weight units (although we should join the British in abolishing the troy pound which has no purpose but to cause occasional confusion).

The standardization problem is not divided into "left" and "right". The issue of metric versus English is very similar to the argument about whether to buy a PC or a Mac computer. The software and even some hardware parts are incompatible because of this difference. No one (?) will claim that an IBM clone is any more Communist than a Mac, nor will they claim that a Mac is any more communist than a PC. The main problem isn't in dictionaries. It is mostly in the machine shop. Many of the devices in the machine shop are calibrated to either the metric or the English system. A good machine shop should have devices that are calibrated to anything the customer brings in. Having both metric and English running around doubles the cost of a machine shop. The argument for standardization is not the cost of translation. The problem is that machine parts are not compatible. This can best be seen in the automotive industry. Parts made metric are off and can't be used in English systems, and visa versa. This makes it harder to import or export stuff. If you buy a foreign car, it is difficult to find compatible parts to use in repairs. Therefore, once one buys a foreign car one is obligated to buy foreign. However, the same goes for people buying American stuff. My person experience is with optical devices and breadboards. Suppose one makes a breadboard with holes drilled at distances on or about 1 inch apart. A metric breadboard is drilled at 2.5 inches apart, while an English system. breadboard is drilled at 2.54... apart. I am not gung ho on standardizing our units. I think that it is arguably unnecessary. The costs of changing over will be comparable to the costs of keeping the status quo. Having given my argument for standardization, let me say that I don't think metric belongs everywhere. I don't think it belongs on the road. If we changed our traffic signs from English (miles) to metric (kilometers), there would be an increase in traffic accidents. I don't think it is worth the cost in lives. There are few machines calibrated to miles or kilometers. This would be like the U.S. changing right side of the street driving to left side of the street driving. There would be an increase in accidents since most drivers would be used to the other way of driving. You wouldn't see such a problem in the machine shops. Of course, if the U.S. did change, new drivers in the states would have fewer accidents. However, the increase due to this would be small. I object to you blaming the standardization issue on "leftists" and "liberals." There are as many capitalists on the standardization side as Socialists. It has nothing to do with "political correctness," "the abuse of language," or anything other "political agenda".

I've been using both systems since I can remember. I measure my height in Imperial, buy 2x4's when I need lumber, but I buy gas at 1.04$/litre and I drive my car at 120km/hour. What's wrong with that? But if I had to live with only one of those systems, I'd go SI right now because it's simpler. Working in base 10 always been easier. You want to go on using Imperial, fine with me. But it's an evidence that SI will be THE world standard someday. Sorry to blow your bubble. Francois |
