Area Measure (Metric)

100 square millimeters = 1 sq centimeter

10,000 square centimeters = 1 sq meter = 1,000,000 sq millimeters

100 square meters = 1 are (a)

100 ares = 1 hectare (ha) = 10,000 sq meters

100 hectares = 1 sq kilometer = 1,000,000 sq meters

Area Measure (U.S.)

144 square inches = 1 sq ft

9 square feet = 1 sq yd = 1,296 sq in.

30 1/4 square yards = 1 sq rd = 272 1//4 sq ft.

160 sq rods = 1 acre =4,840 sq yds = 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 (U.S.)

1,728 cubic inches = 1 cu ft.

27 cubic feet = 1 cu yd.

Liquid Measure (U.S.)

When necessary to distinguish the liquid pint or quart from the dry pint or quart, the word "liquid" or the abbreviation "liq" should be used in combination with the name or abbreviation of the liquid unit.

4 gills (gi) = 1 pint (pt) (=28.875 cu in.)

2 pints = 1 quart (qt) (=57.75 cu in.)

4 quarts = 1 gal (=231 cu in.) = 128 fl oz = 1,024 fl drs

60 minims (min.) = 1 fluid dram (fl dr) (= 0.2256 cu in.)

8 fluid drams = 1 fluid ounce (fl oz) (= 1.8047 cu in.)

16 fluid ounces = 1 pt (= 28.875 cu in.) = 128 fl drs

2 pints = 1 qt (= 57.75 cu in.) = 32 fl oz = 256 fl drs

4 quarts = 1 gal (= 231 cu in.) = 128 fl oz = 1,024 fl drs

Dry Measure

When necessary to distinquish the dry pint of quart from the pint of quart; the word "dry" shuld be used in combination with the name or abbreviation of the dry unit.

2 pints = 1 qu (=67.2006 cu in.)

8 quarts = 1 peck (pk) (=537.605 cu in.) = 16 pts
