17. Just so you know NASA was using the metric system during

Mercury, Gemini, Apollo and the Space Shuttle. We lost at least on unmanned mission to Mars because of some idiot contractor calibrating in SAE. BTW- I did work for NASA back in the day and my Mom worked at NASA in Houston from the very beginning. We were suppose to come into the modern world by adapting the Metric System, but "saner" heads prevailed.

In the 1970's there was a major effort to increase the use of the metric system, and Congress passed the Metric Conversion Act of 1975 to speed this process along. However, American consumers generally rejected the use of metric units for highway distances, weather reports, and other common measurements, so little was accomplished except for the encouragement of faster metric conversion in various scientific and technical fields.

In 1988, Congress passed the Omnibus Trade and Competitiveness Act, which designates "the metric system of measurement as the preferred system of weights and measures for United States trade and commerce." Among many other things, the act requires federal agencies to use metric measurements in nearly all of their activities, although there are still exceptions allowing traditional units to be used in documents intended for consumers. The real purpose of the act was to improve the competitiveness of American industry in international markets by encouraging industries to design, produce, and sell products in metric units.

The debate over metric conversion continues. Although metric units have become more familiar and more widely used, the United States remains a "soft metric" country. (The phrase "soft metric" refers to designations like "1 pint (473 mL)" in which metric equivalents are simply tagged onto traditional measurements.)

Proponents of the metric system in the U.S. often claim that "the United States, Liberia, and Burma (or Myanmar) are the only countries that have not adopted the metric system." This statement is not correct with respect to the U.S., and probably it isn't correct with respect to Liberia and Burma, either. The U.S. adopted the metric system in 1866. What the U.S. has failed to do is to restrict or prohibit the use of traditional units in areas touching the ordinary citizen: construction, real estate transactions, retail trade, and education. The U.S. has not made the crucial transition from "soft metric" to "hard metric", so that "1 pint (473 mL)" becomes "500 mL (1.057 pint)", with the traditional equivalent fading into smaller type sizes and finally disappearing.
