Still today we \ntend to convert to the old english system (old generation) but the new \ngeneration are fully imbedded in the SI system.\n\nThe harder part is the temperature system and the volume measures. A big plus \nit is a decimal based system no more 1/64 1/32 and so on odd fraction. As in \nAsterix a small village still resist the conversion...\n\nI remember the advertisement campaign at that time \"don't convert think metric\" \neasier to say than doing.\n\nHere is the excerpt.\n\nMetric Conversion is the process of making metric units, eg, metre (m), litre \n(L), kilogram (kg), degree Celsius (°C), the common units of measurement in \nCanada. Although the metric system was legalized in Canada in 1871, the British \nimperial system of units, based on yards, pounds, gallons, etc, continued to \npredominate. In the 1960s, with rapidly advancing technology and expanding \nworldwide trade, the need for an international measurement system became \nincreasingly apparent. Britain decided to convert to the metric system and the \nUS was studying a similar move.\n\nA number of Canadian associations representing diverse interests, including \nconsumers, educators and professionals, made representations to the government \nfavouring the metric system. In January 1970 the White Paper on Metric \nConversion in Canada set out Canadian government policy. It stated that a \nsingle, coherent measurement system based on metric units should be used for \nall measurement purposes, including legislation. In line with this policy, the \nWeights and Measures Act was amended by Parliament in 1971 to recognize the \nSystème International d'Unités (SI), the latest evolution of the metric system, \nfor use in Canada. Also in 1971, Parliament passed the Consumer Packaging and \nLabelling Act, requiring that metric units be shown on labels of most consumer \nproducts.\n\nTo implement metric conversion the government established a Preparatory \nCommission in 1971, later called Metric Commission Canada. The commission's \nrole was to ensure a planned and co-ordinated conversion in all sectors of the \nCanadian economy and to disseminate information on metric conversion. Beginning \nin 1973 the commission organized over 100 sector committees, with members from \nnational associations and major organizations representing business and \nindustry, consumers, labour, health, education and government. Each sector \ncommittee was responsible for preparing a sector conversion plan and monitoring \nits implementation. The commission as a whole approved sector conversion plans \ndeveloped through consensus.\n\nThe process of replacing imperial units with SI units in all kinds of \ndocuments, measuring devices, manufacturing processes, products and packages \ninvolved a countless variety of tasks. The technical basis for the change to SI \nunits was established by 2 national standards of Canada, the International \nSystem of Units (SI) and the Canadian Metric Practice Guide, first published in \n1973 by the Canadian Standards Association and approved by the Standards \nCouncil of Canada.\n\nAfter choosing appropriate SI units, practical approaches to implementation \nwere debated by sector committees, with each sector determining policies and \nstrategies to suit its interests. Soft conversion (arithmetical conversion of \npre-existing measurement values) versus hard conversion (round, rational values \nin metric units, possibly requiring physical change in product size) was a \nmajor issue. The use of both imperial and metric measurements was another area \nof controversy. Dependence on the US for many parts and products was a \nconstraint for many sectors. The dedicated efforts of Canadian industry allowed \nconversion to proceed with few major problems, although it took 2-5 years \nlonger than planned.\n\n\n\nLuc Leblanc VE2DWE\nSkype VE2DWE\nwww.qsl.net/ve2dwe\nWAC BASIC CW PHONE SATELLITE\n\n \n\n\n",
