International System of Units is sometimes abbreviated . . .

SI

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

Milli

0.000001 one millionith part of

Hecto

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
