In this article on the progress in metrication, the author suggests that is is possible to discern a least-cost, benefit-oriented strategy that attend a transition to SI metric. He terms that a pragmatic view of metrication. Chrysler Corporation is in the process of a long-term, gradual transition. The rate of increase in metric usage is determined by timing of product programs, supplier capability, the trend in the country, and the degree of international involvement in a given product program. He suggests that metrication involves two general types of conversion. The first is conversion to metric language of measurement; the second is the change from engineering standards based on the inch system module to engineering standards based on metric system modules. The problems inherent is such a massive conversion necessitate a set of guidelines and a program definition. Examples of typical guidelines are given. It is also suggested that the transition time, when both systems are in use, be as short as possible. Any metrication program progresses from investigation to planning and implementation. The operational aspects of implementing such a program are discussed. The necessity for a balanced, well-modulated approach is pointed out, in order that diverse units proceed at the same rate. Though the cost of such a program is considerable, metrication must be accomplished in the normal course of business, that is, within the allotted budget. Though no set time has been stated for completion of metrication, the general consensus is that the optimum time frame can be inferred from the normal cycle for regeneration of products and replacement of tools and machinery. Any proper timing policy will set the pace of metrication at a level that assures progress at a reasonable cost. The author portrays metrication as both a challenge and an opportunity. There must be joint planning, close communication, and coordination among industry and company groups. One of the most useful mechanisms in this regard will be the American National Metric Council. There must be attention to the importance of standards. The emphasis in the article is that the metrication rate should be paced by the new product cycle. The author suggests that legislative schedules and regulations would cause additional costs and disruptions.
