Metric Occupational Training Workbooks

Metric System (SI) knowledge and fluency in metric measurement usage is a valuable workforce skill set. SI skills and abilities can set personnel apart from others that do not have metric experience. Here are a few tips when implementing metric training within an organization:

  • Define the learner audience. Determine who within the organization needs to know the metric system and to what extent they need to know it. Some personnel may require an in-depth working knowledge, while others may need to know less. Most will likely need to know only a few metric units. Defining the learner audience will help minimize training expenses, one of the primary costs of metrication.
  • Train only as needed. Train only as necessary to meet the goal of enabling personnel to perform their jobs with the same or greater efficiency using metric measurements. Training can often be accomplished completely on-the-job (OJT).
  • Train at the right time. Metric system training should take place just prior to when personnel will use the new knowledge on-the-job. Training earlier than needed is usually ineffective because there isn't an opportunity for workers to immediately apply or practice the new skills.

The Metric Occupational Training workbook series was developed in the 1970's by the Center for Vocational Education with the U.S. Department of Health Education and Welfare's Bureau of Occupational and Adult Education to provide useful educational information on length, area, volume, weight, temperature, and unit conversion. The workbooks include learning activities and quizzes that apply metric measurements within a variety of occupations but should be interpreted for today's occupations.
