Dry Measure

Dry Measure

When necessary to distingush the dry pint or quart from the liquid pint or quart, the word “dry” should be used in combination with the name or abbreviation of the dry unit.

 

2 pints	=	1 qt 67.2006 cu in.
8 quarts	=	1 peck (pk) 537.605 cu in. 16 pts
4 pecks	=	1 bushel (bu) 2,150.42 cu in. 32 pts

 

Avoirdupois Weight

When necessary to distinguish the avoirdupois dram from the apothecaries' dram, or to distinguish the avoirdupois dram or ounce from the fluid dram or ounce, or to distinguish the avoirdupois ounce or pound from the troy or apothecaries' ounce or pound, the word “avoirdupois” or the abbreviation “avdp” should be used in combination with the name or abbreviation of the avoirdupois unit. (The “grain” is the same in avoirdupois, troy and apothecaries' weights.)

 

27 11/32 grains	=	1 dram (dr)
16 drams	=	1 oz 437 ½ grains
16 ounces	=	1 lb 256 drams 7,000 grains
100 pounds	=	1 hundredweight (cwt)*
20 hundredweights	=	1 ton (tn) 2,000 lbs*

In “gross” or “long” measure, the following values are recognized:

 

112 pounds 20 gross or long	=	1 gross or long cwt*
hundredweights	=	1 gross or long ton 2,240 lbs*

 

When the terms “hundredweight” and “ton” are used unmodified, they are commonly understood to mean the 100-pound hundredweight and the 2,000-pound ton, respectively; these units may be designed “net” or “short” when necessary to distinguish them from the corresponding units in gross or long measure.
