Study Notes
Metric System
- Mass: g or gram
- Length: m or meter
- Volume: L or liter
- 1 cubic centimeter (cc) of water is roughly equal to 1 milliliter (mL) and weighs 1 gram.
Apothecary System
-
Volume (fluids):
- 60 minims (mm) = 1 fluidrachm/fluidram (f 3)
- 8 fluidrachms = 1 fluid ounce (f 3)
- 16 fluid ounces = 1 pint (pt)
- 2 pints = 1 quart (qt)
- 4 quarts = 1 gallon (gal)
-
Mass (weight):
- 20 grains (gr) = 1 scruple (3)
- 3 scruples = 1 drachm/dram (3)
- 8 drachms = 1 ounce (3)
- 12 ounces = 1 pound (lb)
Avoirdupois System
-
Volume:
- 1 fluidrachm = 60 minims
- 1 fluid ounce = 8 fluid drams = 480 minims
- 1 pint = 16 fluid ounces = 7680 minims
- 1 quart = 2 pints = 32 fluid ounces = 15360 minims
- 1 gallon = 4 quarts = 128 fluid ounces = 7680 fluid drams
-
Mass (weight):
- The grain is common to both the apothecary and avoirdupois systems
- 437.5 grains = 1 ounce
- 16 ounces = 1 pound
Exact Equivalents
-
Length:
- 1 meter = 39.37 inches
- 1 inch = 2.54 centimeters
-
Volume:
- 1 milliliter = 16.23 minims
- 1 minim = 0.06 milliliters
- 1 fluid dram = 3.69 milliliters
- 1 fluid dram = 29.57 milliliters
- 1 pint = 473 milliliters
- 1 US gallon = 3785 milliliters
-
Mass:
- 1 gram = 15.432 grains
- 1 kilogram = 2.20 pounds (avoirdupois)
- 1 grain = 0.065 grams or 65 milligrams
- 1 ounce (avoirdupois) = 28.35 grams
- 1 dram (apothecary) = 31.1 grams
- 1 pound (avoirdupois) = 454 grams
- 1 pound (apothecary) = 373.2 grams
Other Equivalents
- 1 ounce (avoirdupois) = 437.5 grains
- 1 dram (apothecary) = 480 grains
- 1 US gallon = 128 fluid drams
- 1 fluid dram (of water) = 455 grains
- 1 grain (apothecary) = 1 grain (avoirdupois)
Approximate Equivalents
- 1 fluid dram = 1 teaspoonful = 5 mL
- 4 fluid ounces = 120 mL
- 8 fluid ounces = 1 cup = 240 mL
- 1 grain = 65 mg
- 1 kilogram ≈ 2.2 pounds (lb)
