The purpose of this study was the identification of effective means of educating the general public to think in terms of the metric system. Toward this end, extension home eoncomists in New York State were surveyed concerning their plans to implement teaching of the metric system. A literature review was conducted over four basic topics: (1) experiences of other nations adopting the metric system, (2) recent changes of a similar nature (e.g., Britain's adoption of decimal currency), (3) the role of change agents, and (4) characteristics of adult learners. The major findings involved the importance of using mass media in educating the public. Several suggestions to Cooperative Extension Services are provided. (SD)
