 Gram is used to measure . . . weight Liter is used to measure . . . volume Meter is used to measure . . . length Doses are calculated using metric measurements that relate to . . . weight and volume Of the three things above, what isn't used to calculate doses? Meter isn't used to calculate doses International System of Units is sometimes abbreviated . . . SI an abbreviation for the French System International d'Unites why do we use the metric system and not the Apothecary system? metric is more precise Ex babies are weighed in grams & kilograms, and adults in kilograms, not lbs. & oz.s what is used to measure someone's height? linear measurements in meter & centimeters Kilo 1,000 one thousand times Centi 0.01 one hundreths part Milli 0.001 one thousanths part of Micro 0.000001 one millionith part of Hecto 100 one hundred times Deka 10 ten times Deci o.1 one tenth mcg means ? microgram or µg BUT don't use µg b/c it looks like mg and can cause lots of trouble, see why? is it ml or mL ? mL the L is capitalized on purpose gram will be used as gm or Gm what are we talking about? Use standard SI notation Ex gram g microgram mcg milligram mg kilogram kg liter L milliliter mL we don't use quanities with a fraction . . . use: 0.4g or 0/5L NOT 2/5 g or 1/2 L write the abbrevations where? after the quanity Ex 1,000 mg NOT mg 1,000 weight is in grams 1,000 mg = ? 1 g Volume uses the what abbreviation? L for Liter 1,000 mL = 1 L 1mL = 0.001 L cubic centimeter is how much space? the space 1mL of liquid occupies abbreviated as cc mL and cc are used interchangibly BUT mL is used for volume, not cc! ************************** See, a cup will show mL on its side, not cc's. Got to memorize this: 1 kilogram kg = 1,000 g 1 gram g = 1,000 milligrams mg 1 milligram mg = 1,0000 what??? mcg Got to memorize this: 1 Liter = 1,000 milliliters theres the deal with pints and quarts being almost the same as metric. what about this? the thing is pints & quarts aren't used around hospital areas BUT you'll run into it in a home enviroment so you have to know it for that so 1 pint ≈ 500 mL 1 quart ≈ 1,000 mL whats wrong here? not exact, both Apothocary units are less than the metric Conversions b/t Metric Units Now Rule 1 to convert a smaller unit to a larger one, ...? divide by moving the decimal point 3 places to the left Ex 100mL = 0.1L another example of converting a smaller unit to a larger one ... Ex 50mg = ...? 50 mg = 0.05g Placing the zero in front of the decimal is a BIG DEAL To convert a larger number to a smaller one, what? multiply by moving the decimal 3 places to the right Ex 0.75g = 750mg Ex 0.04kg = 40g
