(6 mi. sq.) = 1 township (tp.) = 2,304 a.   Cubic Measure               1728 cubic inches (cu. in.) = 1 cubic foot (cu. ft.)             27 cu. ft. = 1 cubic yard (cu. yd.)   United States Liquid Measure               4 gills (gi) = 1 pint (pt)             2 pt. = 1 quart (qt) = 8 gills             4 qt. = 1 gallon (gal.) = 8 pints = 32 gills             31½ gal. = 1 barrel (bbl) = 126 quarts.             2 bbl. = 1 hogshead (hhd) = 63 gallons = 252 quarts.   Apothecaries' Fluid Measure               60 minims (m.) = 1 fluid dram (fl. dr.)             8 fl. dr. = 1 fluid ounce (fl. oz.) = 480 minims             16 fl. oz. = 1 pint (0) = 128 fl. dr. = 7,680 m.             8 0. = 1 gallon (cong.) = 128 fl. oz. = 1,024 fl. dr.   U.S. Dry Measure               2 pints (pt.) = 1 quart (qt.)             8 qt. = 1 peck (pk) = 16 pints             4 pk. = 1 bushel (bu.) = 32 quarts = 64 pints             105 quarts = 1 barrel (for fruits and vegetables) = 7,056 cubic inches.   Avoirdupois Weight               27 11/32 grains (gr.) = 1 dram (dr.)             16 dr. = 1 ounce (oz.) = 437½ grains             16 oz. = 1 pound (lb.) = 156 drams = 7000 grains             100 lbs. = 1 hundred weight (cwt.) = 1600 ounces             20 cwt. = 1 ton (t.) = 2,000 pounds   Troy Weight               24 grains (gr.) 1 pennyweight (dwt.)             20 dwt. = 1 ounce (oz.) = 480 grains             12 oz. = 1 pound (lb.) = 240 dwt. = 5,760 gr.   Apothecaries' Weight               20 grains (gr.) = scruple             3 scruples = 1 dram = 60 grains             8 drams = 1 ounce = 24 scruples = 480 grains             12 ounces = 1 pound (lb.) = 96 drams = 288 scruples =             5,760 grains   The Metric System   The metric system is based on a unit of length (the meter.). A cubic box one-tenth of a meter on the side has the unit of capacity, a liter, and the water contained in a liter weighs one kilogram.  The unit of weight, the gram, in the metric system is the weight of water contained in a cubical box one-hundredth of a meter on a side. (Note: These values are not precisely correct but hold for all but the most refined measurements.)   The entire system is then built up by multiplying or dividing the unit by ten, one hundred and one thousand, using always the same prefix to indicate what the unit is multiplied or divided by, thus:   milli means 1/1000 or divided by 1000 centi means 1/100 or divided by 100 deci means 1/10 or divided by 10 deka means 10 or multiplied by 10 hecto means 100 or multiplied by 100 kilo means 1000 or multiplied by 1000   The tables then become:               Length   10 milli-meters = 1 centi-meter 10 centi-meters = 1 deci-meter 10 deci-meters = 1 meter 10 meters = 1 deka-meter 10 deka-meters = 1 hecto-meter 10 hecto-meters = 1 kilo-meter               Weight   10 milli-grams = 1 centi-gram 10 centi-grams = 1 deci-gram 10 deci-grams = 1 gram 10 grams = 1 deka-gram 10 deka-grams = 1 hecto-gram 10 hecto-grams = 1 kilogram               Capacity   10 milli-liters = 1 centi-liter 10 centi-liters = 1 deci-liter 10 deci-liters = 1 liter (1 cubic deci-meter) 10 liters = 1 deka-liter 10 deka-liters = 1 hecto-liter 10 hecto-liters = 1 kilo-liter               Area   100 sq. meters = 1 are. 100 are. = 1 hectare 100 hectares = 1 sq. kilometer   In the metric system there is but one standard of weight, one standard of measure for liquids and dry commodities alike, and but one standard of length.   (Source:  Amended at 22 Ill.
