*Assumption 1: No concerted national program to increase the use of the metric measurement units and/or metric engineering standards in a world of increasing metric usage.

Assumption 2: A nationally planned program to increase the use of SI metric measurement units (language
only). After a 10-year period of transition, SI metric measurement units will be used throughout the U.S. in
all new and revised documents except for describing existing customary hardware, replacement parts therefor,
and interfaces therewith.

Assumption 3: A nationally planned program to increase the use of metric measurement units and metric
engineering standards. Metric engineering standards, as well as metric measurement units, will be used for all
new and redesigned products after a 10-year period of transition.

** This figure includes only those respondents who do not anticipate that they will increase metric usage under
Assumption I. The figure for NASA is a special case, however, because there are some groups at each Center
which do not plan on increased usage, but who expect problems.

Under Assumption II, five respondents favor a shorter transition period than 10 years, 13 favor a 10-year

transition period, and no respondents favor a transition period longer than 10 years.

2 Under Assumption II, four respondents favor a shorter transition period than 10 years, eight favor a 10-year
transition period, and none favor a transition period longer than 10 years.

3 A total of 51 questionnaires were submitted by HSMHA; however, there was a set of duplicate responses
(from Health Facilities Construction Branch, Headquarters of the Indian Health Service) and one questionnaire
(National Clearinghouse for Smoking and Health) was returned untouched.

Under Assumption II, two respondents favor a shorter transition period than 10 years, one favors a 10-year transition period, and none favors a transition period longer than 10 years.

3 Under Assumption II, one respondent favors a shorter transition period than 10 years, 10 favor a 10-year
transition period, and one favors a transition period longer than 10 years.

"Under Assumption II, three respondents favor a shorter period than 10 years, nine respondents favor a
10-year transition period, and one respondent favors a longer period.

* Five questionnaires were submitted by USIA, however, two were untouched.
