That's a pretty nifty website that was presented on the USMA mail list.
I knew of its predecessor SR-22 (?) when it comprised only a
downloadable database and one had to use M$ Access to use it. It's a
pleasure to see it in a more user-friendly form now at
http://www.nal.usda.gov/fnic/foodcomp/cgi-bin/measure.pl
Years ago, my Registered Dietitian wife and I used Handbook 8. We've
come a long way!
Now, if we could just get them to use the correct symbol for micrograms!
Ironically, in Appendix B (p 72) of the documentation
http://www.ars.usda.gov/SP2UserFiles/Place/12354500/Data/SR23/sr23_doc.pdf
both μg and mcg are shown -- in that order. Further, μg is used
throughout their text in that documentation and mcg is used only in one
field name. But in using the GUIed website, I saw mcg used in the Units
column -- no μg.
Also, I could find no description in the documentation or the GUIed
website as to what was meant by "cup" and "teaspoon". The FDA uses the
definition of a teaspoon (tsp) as 5 mL. The traditional teaspoon (in the
U.S.) is 1/3 of a tablespoon or 1/6 of a fluid ounce, making it 1/48 of
a cup. Using the data for sugar (4.2 g/tsp, 200 g/cup) it appears that
this system uses the 5 mL teaspoon but the true definition of a liquid
cup: 1/4 quart or (0.946352/4) L. That would mean that this system uses
liquid measures throughout, even for dry products. The latter of course,
are traditionally measured in dry quarts, pecks, and bushels --
especially for produce (fruits and vegetables). Of course, Americans,
who tend to measure recipe ingredients by volume instead of by mass, use
only one set of measuring cups in the kitchen. And those probably are
liquid cups.
