Dear Bruce, In a recent posting to the USMA listserver (Re: [USMA:20377] Re: Billion definition) you stated:
Standard IEEE/ASTM SI 10-1997, (is) the primary American National Standard on metric practice, Could you elaborate on this a little further for me please? How do NIST Special documents 330 and 811 fit into the hierarchy that you imply? I am not disagreeing with you, I simply don't know how the system works in the USA. Thanks for your help.
