Should U.S. switich its measurment system?

 

   Several years ago, NASA failed its rocket, and main reason of this accident is because NASA did not use the same measure system as other countries.  In addition, a new issue occurred which is should U.S. switch the measurement to metric system.  I myself support this suggestion.  First, different measure systems can make the students chaotic, especially a immigrant student.  In China, everyone learns metric system; thus, the Chinese students do not know what are "mile", "inch", or "feet".  When I came to the United States fire\st time, I did not have the concepts of U.S. measure system.  Furthermore, various measure systems may cause some accidents, such as the issue of NASA.  On the other hand, the metric system is an international system, so most countries use this measure system.
