Brian, Harry, Pat sirs: >The cm vs. mm debates may be technically interesting, but they do not do much >toward actually advancing metrication. I agree and plead .....THERE IS NO LIMIT TO ARGUMENTS; since both cm (centi+Metre) and mm (milli+Metre) are sub-units of the METRE and hence Le Systeme International d'Unites (SI). Is is the realisation of base unit - METRE i.e. of imprtance! AND let this not be confused with *how individuals use it and with WHAT measurement occasion!*. By occasion, I mean: Astronomical distances; Distances between 'Towns'; Measuring HIGHT of humans; the Laboratory measurements or the Measurements used in Atomic/sub-atomic particle. The common and natural unit to replace Yard is NAURALLY the Metre! How far do we rate the invention of Metre is a matter of acceptance 'French vs British'? But, British INCH was almost getting the status of ".....a universal measure". My investigation and linking the Indus inch - a unit linked to British inch with METRE take me down to Indus Metre and hence to ancient India via: http://www.brijvij.com/indusEvidence.doc and http://www.brijvij.com/bbv_Ind-stps.aZtec_brCal-links.pdf. Imprtance today is the realisation of METRE and its length rather than 'confusion between cm & mm' which seem to me a practical way for using the Metre which I place as: "METRE is the arc-length represented by 1/100th of Pi/180 (one degree), at Earth centre".

This whole cm vs mm thing is nonsense. It really doesn't matter. My skis are 168 cm....I know that's 1680 mm. I know 2.4 km is 2400 meters. Ok....we all get it. That's what makes the metric system so easy. So--grab a 250 mL (or 25 cL) glass of wine, take a sip and relax. This has to go down as one of the dumbest threads on this list yet-- centimeter hatred. Now that's rich. -------- Original Message -------- Subject: [USMA:50601] cm vs. mm From: Harry Wyeth <hbwy...@earthlink.net> Date: Sun, June 12, 2011 9:01 pm To: "U.S. Metric Association" <usma@colostate.edu> Cc: "U.S. Metric Association" <usma@colostate.edu> May I suggest that the issue of mm vs. cm is pretty low on the agenda for moving forward with adoption of the metric system in the US? I know that Aussies usually refer to short measurements in mm, which is fine. But if an American wants to order a piece of plywood cut at the lumber yard as, say, 155 x 80 cm, I would be really pleased (I once overheard a Kiwi--NZ citizen--asking just such a thing). Telling someone that an easy way to know what a cm is by referring to his finger can be useful. Same with the distance of 10 cm or 100 mm with reference to a palm width. I personally find it easier to visualize the size of a cat, for example, as perhaps 40 cm long than 400 mm. The key to adopting the metric system in the US is just to use it. It doesn't matter if people use it incorrectly at first, or use cm instead of mm, or even use kms instead of km, or KM, or even kph. What we need is leadership from government--this has always been my belief--which could start with, for example, weighing mail in grams and measuring postal packages in mm or cm and on and on. My favorite easy one would be selling milk in liter dairy cartons, as they do in Canada and Australia and probably everywhere else. The cm vs. mm debates may be technically interesting, but they do not do much toward actually advancing metrication. HARRY WYETH
