TABLES OF U.S. UNITS OF MEASUREMENT [Анг.]

In these tables where foot or mile is underlined, it is survey foot or U.S. statute mile rather than international foot or mile that is meant.

Units of Length
12 inches (in) = 1 foot (ft)
3 feet = 1 yard (yd)
16-1/2 feet = 1 rod (rd), pole, or perch
40 rods = 1 furlong (fur) = 660 feet
8 furlongs = 1 U.S. statute mile (mi) = 5280 feet
1852 meters = 6076.115 49 feet (approximately)
= 1 international nautical mile

Units of Area
144 square inches (in2) = 1 square foot (ft2)
9 square feet = 1 square yard (yd2)
= 1296 square inches
272-1/4 square feet = 1 square rod (sq rd)
160 square rods = 1 acre = 43 560 square feet
640 acre = 1 square mile (mi2)
1 mile square = 1 section of land
6 miles square = 1 township
= 36 sections = 36 square miles

Units of Volume
1728 cubic inches (in3) = 1 cubic foot (ft3)
27 cubic feet = 1 cubic yard (yd3)

Gunter's or Surveyors Chain Units of Measurement
0.66 foot (ft) = 1 link (li)
100 links = 1 chain (ch)
= 4 rods = 66 feet
80 chains = 1 U.S. statute mile (mi)
= 320 rods = 5280 feet

Units of Liquid Volume
4 gills (gi) = 1 pint (pt)= 28.875 cubic inches
2 pints = 1 quart (qt) = 57.75 cubic inches
4 quarts = 1 gallon (gal) = 231 cubic inches
= 8 pints = 32 gills

Apothecaries Units of Liquid Volume
60 minims (min or ) = 1 fluid dram (fl dr or f )
= 0.225 6 cubic inch
8 fluid drams = 1 fluid ounce (fl oz or f)
= 1.804 7 cubic inches
16 fluid ounces = 1 pint (pt or )
= 28.875 cubic inches
= 128 fluid drams
2 pints = 1 quart (qt) = 57.75 cubic inches
= 32 fluid ounces = 256 fluid drams
4 quarts = 1 gallon (gal) = 231 cubic inches
= 128 fluid ounces = 1024 fluid drams

Units of Dry Volume
2 pints (pt) = 1 quart (qt) = 67.200 6 cubic inches
8 quarts = 1 peck (pk) = 537.605 cubic inches
= 16 pints
4 pecks = 1 bushel (bu) = 2150.42 cubic inches
= 32 quarts

Avoirdupois Units of Mass
[The "grain" is the same in avoirdupois, troy, and apothecaries units of mass.]
27-11/32 grains = 1 dram (dr)
16 drams = 1 ounce (oz)
= 437-1/2 grains
16 ounces = 1 pound (lb)
= 256 drams
= 7000 grains
100 pounds = 1 hundredweight (cwt)
20 hundredweights = 1 ton
= 2000 pounds

In "gross" or "long" measure, the following values are recognized:
112 pounds = 1 gross or long hundredweight
20 gross or long hundredweights = 1 gross or long ton
= 2240 pounds

Troy Units of Mass
[The "grain" is the same in avoirdupois, troy, and apothecaries units of mass.]
24 grains = 1 pennyweight (dwt)
20 pennyweights = 1 ounce troy (oz t)= 480 grains
12 ounces troy = 1 pound troy (lb t)
= 240 pennyweights = 5760 grains

Apothecaries Units of Mass
[The "grain" is the same in avoirdupois, troy, and apothecaries units of mass.]
20 grains = 1 scruple (s ap or )
3 scruples = 1 dram apothe-caries (dr ap or )
= 60 grains
8 drams apothecaries = 1 ounce apothecaries (oz ap or )
= 24 scruples = 480 grains
12 ounces apothecaries = 1 pound apothecaries (lb ap)
= 96 drams apothecaries
= 288 scruples = 5760 grains
