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.)

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.
