The widespread use of the metric system by most of the major industrial powers of the world has prompted the Canadian government to investigate and consider use of the system. This booklet was developed to aid the consuming public in Canada in gaining some knowledge of metrication and how its application would affect their present economy. Included are: (1) an operational definition of metrication, (2) an explanation of the planned conversion process and what it would mean in terms of automobiles, food, clothing, furnishings, hardware and lumber, household equipment, paper, maps, weather, drugs, postage rates, and photographic materials, and (3) anticipated problems with the system resulting from conversion.
