It was also designed as a logical system, tied to defined physical constants. I recently watched a video about how the new standard for a kilogram was the number of atoms in a precisely measured silicon sphere. The kilometre was originally defined in relation to the distance from the equator to the poles, but is currently determined by the wavelength of light emitted by the kryton-86 items. This shows the metric system is defined in terms of physical constants and not some unmeasurable item such as the length of a long dead king's arm. > > If a country is serious about a change, than all measures must be > provided for a while in both units and after while the old units must > disappear. In Canada, when Km and °C came in, there was a switch over date, the road sides had stickers placed over the old speed limit in miles to show in Km. Weather reporting swithed to Celcius. As for physical things, there was a date given, where dimensions had to be specified in metric, but this applied to things made after that date and older items could still be sold. However, manufacturers switched production well before that date. The switch over was also phased in, so only one thing changed at a time. -- To unsubscribe e-mail to: users+unsubscr...@global.libreoffice.org Problems? http://www.libreoffice.org/get-help/mailing-lists/how-to-unsubscribe/ Posting guidelines + more: http://wiki.documentfoundation.org/Netiquette List archive: http://listarchives.libreoffice.org/global/users/ All messages sent to this list will be publicly archived and cannot be deleted
