a pound is 16 oz.(by weight) technical name avoirdupois ounce and 16
fluid oz is a pint (by volume). Also take into consideration imperial and
US fluid ounce differ as well. Imperial ounces are smaller in size.

There is no comparision between weight and volume. Denser stuff weighs
more for the same size or volume...but fill the same volume. for example
1 pound of water or 16 avoirdupois ounces can be converted to 16.68 fluid
ounces note the difference.


....a pound of lead and a pound of feathers both weigh the same... a pound
of lead wouldn't be a full 8 fliud ounces (I'm guessing here and guess at
less than 1 fluid oz for the 1 pound of lead.) Whereas the 1 pound of
feathers would be multiple 8 ounce measuring cups probably a gallon or
more. A gallon is 16 cups.

There are scales that will convert weight to mass...but they use a code
for each item and come with a booklet with the codes. These booklets are
not very informitive...you get a conversion code for flour but not for
wheat groats etc or whole wheat or rye flour etc...You are better off
creating your own booklet by weighing ingredients by cup and writing it
down and then using your info to get correct weight to volume conversion.
But change brands of an item and all bets are off.
