WITHIN SYSTEMS
MEMORIZE:
1 gram (g or G) = 1000 milligrams (mg)1 liter (l or L) = 1000 milliliters (ml or
mL)3 teaspoons (t) = 1 tablespoon (T) 1 cubic centimeter (cc) = 1 milliliter (ml)

BETWEEN SYSTEMS
MEMORIZE: 1 gram (G, GM, gm) = 15 grains (gr) 60 milligrams (mg) = 1 grain (gr) 1 tablespoon (T) = 15 ml 1 kilogram (kg) = 2.2 pounds (lb) 1 ounce (oz) = 30 ml or 30 cc 1 cc = 15 drops (gtt) or 15 minims (mx) 1 inch (in) = 2.5 centimeters (cm)

STEPS TO CONVERSION

WITHIN SYSTEMS1) Write down what you know in a ratio
or fraction format:
Example: 1 Gram 1000 milligrams
![Page 10: DRUG CALCULATIONS MAKING IT EASY. CLASS OUTLINE 1) review roman numerals 2) review apothecary measurements 3) review conversions 4) review 3 steps.](https://reader030.fdocuments.in/reader030/viewer/2022032703/56649d385503460f94a11c8c/html5/thumbnails/10.jpg)
2) Write down what you desire in a ratio or fraction format to complete the proportion:
Example: 3 Grams x milligrams
![Page 11: DRUG CALCULATIONS MAKING IT EASY. CLASS OUTLINE 1) review roman numerals 2) review apothecary measurements 3) review conversions 4) review 3 steps.](https://reader030.fdocuments.in/reader030/viewer/2022032703/56649d385503460f94a11c8c/html5/thumbnails/11.jpg)
Remember:
The numerator and denominator must be the same unit of measurement
The unknown value is referred to as “x”
![Page 12: DRUG CALCULATIONS MAKING IT EASY. CLASS OUTLINE 1) review roman numerals 2) review apothecary measurements 3) review conversions 4) review 3 steps.](https://reader030.fdocuments.in/reader030/viewer/2022032703/56649d385503460f94a11c8c/html5/thumbnails/12.jpg)
The completed proportion:
1 Gram 3 Grams 1000 mg : : x milligrams
Cross multiply
![Page 13: DRUG CALCULATIONS MAKING IT EASY. CLASS OUTLINE 1) review roman numerals 2) review apothecary measurements 3) review conversions 4) review 3 steps.](https://reader030.fdocuments.in/reader030/viewer/2022032703/56649d385503460f94a11c8c/html5/thumbnails/13.jpg)
1 GM x X mg(s) = 3 GM x 1000 mg Drop the terms used for units of
measurement: 1 X = 3(1000)Solve for X: divide both sides of the
equation by the number preceding X:X = 3000 1 1 X = 3000

BETWEEN SYSTEMS
1) Write down what you know in a fraction format:
15 grains 1 gram
![Page 15: DRUG CALCULATIONS MAKING IT EASY. CLASS OUTLINE 1) review roman numerals 2) review apothecary measurements 3) review conversions 4) review 3 steps.](https://reader030.fdocuments.in/reader030/viewer/2022032703/56649d385503460f94a11c8c/html5/thumbnails/15.jpg)
2) Complete the proportion by writing down what you desire:
15 grains 30 grains 1 gram : : X grams
HINT: Keep the units of measurements in the correct spaces!
![Page 16: DRUG CALCULATIONS MAKING IT EASY. CLASS OUTLINE 1) review roman numerals 2) review apothecary measurements 3) review conversions 4) review 3 steps.](https://reader030.fdocuments.in/reader030/viewer/2022032703/56649d385503460f94a11c8c/html5/thumbnails/16.jpg)
Drop the units of measurement Cross multiply
15 x X = 30 x 1 15X = 30
Solve for X: Divide each side by the number in front of X : X = 2 ANS: 2 Grams
