practically all other English-speaking countries. In addition, it will
be well to have a knowledge of relative weights and measures, so as to
be in a position to use these tables to the best advantage.

31. The table used ordinarily for weighing foods is the table of
AVOIRDUPOIS WEIGHT. Another table of weights, called the table of _Troy
weight_, is used by goldsmiths and jewelers for weighing precious
metals. It should not be confused with avoirdupois weight, however,
because its pound contains only 12 ounces, whereas the avoirdupois pound
contains 16 ounces. The table of avoirdupois weight, together with the
abbreviations of the terms used in it, is as follows:

AVOIRDUPOIS WEIGHT
437-1/2 grains (gr.)..... = 1 ounce............. oz.
16 ounces................ = 1 pound............. lb.
100 pounds............... = 1 hundredweight..... cwt.
20 hundredweight \
}....... = 1 ton............... T.
2,000 pounds /

Although 2,000 pounds make 1 ton, it is well to note that 2,240 pounds
make 1 _long ton_ (L.T.). The long ton is used by coal dealers in some
localities, but the ton, sometimes called the _short ton_, is in more
general use and is the one meant unless long ton is specified.

32. The table of LIQUID MEASURE is used for measuring all liquids, and
is extremely useful to the housewife. This table, together with the
abbreviations of its terms, is as follows:
