metric system

* portions increased ( multiplied) or decreased (divided) by multiples of 10 (10-100-1,000) *conversions achieved by moving decimal point to the right for multiplication or to the left for division,

converting within the same system

*determine the equivalent values *write down what you know in a fraction, followed by what you desire and solve for example: how many mL in 2.5 ounces? 75ml 1. look up equivalent of 30ml=1 oz. 2. write down what you know: 30 ml/1 ounce 3. you want XmL/2.5 ounces 4. cross multiply: 30 ml/1 oz X xmL/2.5 oz =30ml/2.5 oz = 75 mL

metric apothecary & household equivalents

gtt-drop 4ml-dram 15 ml - 4 drams 1 tbsp. 30 ml - 8 drams - 2 tbsp. = 1 ounce 1 kg (1,000 g) = 2.2 lb. 1 mg = 1,000 mcg 2.5 cm = 1 inch

converting smaller to larger unit

move decimal point to the left 1/1L - 10/10dl- 100/100cL - 1,000/1,000 mL

converting larger unit to smaller unit

move decimal point to the right multiple by 10 * 1/1 liter 10/10 deciliters 100/100 centiliters 1000/ 1,000 ml

ratio and porportion

select equivalent value and then set up proportion using colon or fraction format example: Give 1.5 ounces of an elixir that is available in ml 1.change ounces to ml, equivalent value :30 ml= 1 ounce 2. write what you know: 30ml:1 oz = Xml:1.5 oz 3. solve for X: x=30 X 1.5 =45 ml
