On November 28, 2001, NASA Public Affairs Office issued a new policy on use of the metric system (below) that responds to Recommendation 8 in G-00-021, Assessment of NASA's Use of the Metric System. We appreciate the positive step the Office of Public Affairs has taken by developing a formal metric use policy. Although we feel that the policy could certainly be stronger, the policy appears to set a reasonable balance between the Government's desire to increase use of the metric system and the need to ensure that NASA press releases are easily understood by the public. All recommendations of this report are now considered closed.
METRIC USE POLLICY FOR NASA PUBLIC AFFAIRS Section 5164 of Public Law 100-418, the Omnibus Trade and Competitiveness Act of 1988, directs executive branch departments and agencies to: -- use, to the extent economically feasible, the metric system in procurements, grants and other business-related activities, and -- seek out ways to increase understanding of the metric system of measurement through educational information and guidance, and in government publications. In an attempt to more clearly comply with the spirit of the law, NASA's Office of Public Affairs will adopt a more formal metric use policy. It is NASA policy to use language that most clearly illustrates the story. Metric terms should be included in a story when they are relevant. -- Use metric terms on first reference when they are the primary form in which the source of a story has provided statistics. Follow the metric units with equivalents in the terms more widely known in the United States. Normally, the imperial equivalent should be in parentheses after the metric figure. A general statement such as "A kilometer equals about five-eighths of a mile" would be acceptable. However, avoid repeated use of parenthetical remarks in a story that uses kilometers many times. There may also be times when a more general imperial conversion best communicates the thought. Writing "about the length of a football field" may be a more clear illustration than simply adding a standard "(120 yards)" parenthetical conversion to a press release. -- There is no need to provide imperial equivalents if the metric standard has become more widely known. For example, most Americans are familiar with 2-liter soft drink measurements. There is no reason to convert to imperial ounces. -- If the mission uses imperial measurements, there is no need to provide a metric conversion unless the conversion more clearly articulates the thought.
