I looked at ISO-31 (1999 version or thereabouts) a year or two ago. I could not make a copy of it because of copyright rules. However I did notice that it listed miles, yards, feet and inches as deprecated units.
Standards and recommendations such as this do not necessarily have the force of law in many countries, but in the event of a dispute they will often be deemed persuasive evidence. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of John M. Steele Sent: 14 March 2009 15:21 To: U.S. Metric Association Subject: [USMA:43817] Re: Units for international trade I Have never heard of it. Having skimmed it, it seems willing to accomodate not only SI units, but also Imperial, Customary, and any other units used widely enough. Its main orientation seems to be assigning a TLA (three letter acronym) to every unit so it can be communicated by Telex (does anyone still use Telex?) With the tables of interest removed from the ASCII copy, I have no clue if it is reasonable. The SI units have official symbols which I think are clearly preferable to TLAs. For the Customary units, we will probably arrogantly use our own standard abbreviations (given in FPLA and UPLR), the rest of the world be damned. :) None of ours conflict with SI. Brit use of "m" for miles is objectionable, but I am not aware of other conflicts. Certainly identification of US vs UK unit (where a difference exists) could be important in the list. Since the tables are removed, I can't tell if this is achieved. --- On Sat, 3/14/09, Pat Naughtin <[email protected]> wrote: > From: Pat Naughtin <[email protected]> > Subject: [USMA:43815] Units for international trade > To: "U.S. Metric Association" <[email protected]> > Date: Saturday, March 14, 2009, 6:18 AM > Dear All, > > Can anyone tell me anything about this document, and its > current world status as opposed to its status in the > European community? > > http://www.unece.org/trade/untdid/download/r1224.txt > > Cheers, > > Pat Naughtin > > PO Box 305 Belmont 3216, > Geelong, Australia > Phone: 61 3 5241 2008 > > Metric system consultant, writer, and speaker, Pat > Naughtin, has helped thousands of people and hundreds of > companies upgrade to the modern metric system smoothly, > quickly, and so economically that they now save thousands > each year when buying, processing, or selling for their > businesses.
