United States Linear Measure
12 inches (in.) = 1 foot (ft.) 3 ft. = yard (yd.) = 36 inches 5½ yards = 1 rod (rd.) = 16½ feet 320 rods = 1 mile (mi.) = 1760 yards = 5,280 feet
Chain Measure (Gunter's or Surveyor's Chain)
7.92 inches = 1 link (li.) 100 li. = 1 chain (ch) = 66 feet 80 ch. = 1 mile (mi) The engineer's chain is 100 feet long and consists of 100 links of 12 inches each. 52.8 chains = 1 mile.
Square Measure
144 square inches (sq. in.) = 1 square foot (sq. ft.) 9 sq. ft. = 1 sq. yard (sq. yd.) 30¼ sq. yard = 1 square rod (sq. rd.) = 272¼ sq. ft. 160 sq. rd. = 1 acre (a) = 4,840 sq. yd. = 43,560 sq. ft.
Surveyor's Measure
625 square links (sq. li.) = 1 square rod (sq. rd.) 16 sq. rods = 1 square chain (sq. ch.) 10 sq. ch. = 1 acre (a) 640 a. = 1 square mile (sq. mi.) 36 sq. mi. (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.
