= 43,560 sq ft.
640 acres = 1 sq mi.
1 mile square = 1 section (of land)
6 miles square = 1 township = 36 sections
= 36 sq mi.
Cubic Measure
1,728 cubic inches = 1 cu ft.
27 cubic feet = 1 cu yd
Liquid Measure
4 gills (gi) = 1 pint (pt) (= 28.875 cu in.)
2 pints = 1 quart (qt) (= 57.75 cu in.)
4 quarts = 1 gallon (gal) (= 231 cu in.)
= 8 pts = 32 gills
Apothecaries' Fluid Measure
60 minims (min.) = 1 fluid dram (fl dr) (= 0.2256 cu in.)
8 fluid drams = 1 fluid ounce (fl oz) (= 1.8047 cu in.)

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.)
2711/32 grains = 1 dram (dr)
16 drams = 1 oz = 4371/2 grains
16 ounces = 1 lb = 256 drams = 7,000 grains
100 pounds = 1 hundredweight (cwt)1
20 hundredweights = 1 ton (tn) = 2,000 lbs1
In “gross” or “long” measure, the following values are recognized:
112 pounds = 1 gross or long cwt1
20 gross or long hundredweights = 1 gross or long ton
= 2,240 lbs1
1. 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 designated “net” or “short” when necessary to distinguish them from the corresponding units in gross or long measure.
