Please verify sense 2, "1/25th of a teaspoon — from the 1975 U.S Bureau of Standards"
- what is the "U.S Bureau of Standards"? does this mean NBS (now NIST), or ANSI?
- which 1975 standard? Can't we cite a standard number if this is real?
Maybe this is real, but my gut makes me very suspicious.... 184.108.40.206 08:55, 19 November 2011 (UTC)
- I'd say it's nonsense. Check this  as an example. In order to avoid this becoming another unsolved discussion, I deleted the sense and wrote a usage note. --Hekaheka 06:10, 21 November 2011 (UTC)
