TERMINOLOGY:

UNITS:

gram : common measurement of weight. Used in this table: pg (picograms), g (grams), mg (milligrams), etc. per liter
katal (kat) : a unit of catalytic activity, used especially in the chemistry of enzymes. Used in this table: µkat (microkatals), nkat (nanokatals) per liter
micrometer (µm) : a unit of length. Mean Corpuscular Volume is expressed in cubic micrometers
mole : also “gram molecular weight,” a quantity based on the atomic weight of the substance. Many test results in the Système Internationale are expressed as the number of moles per liter. In US units, these measurements are usually in grams per liter. Used in this table: mmol (millimoles), µmol, (micromoles), nmol (nanomoles), pmol (picomoles) per liter

Some units of measurement include the following fractions and multipliers:
mega (M) : 10 ⁶ or x1,000,000
kilo (k) : 10 ³ or x1,000
deca or deka : 10 ¹ or x10
deci (d) : 10 ^-1 or ÷10
milli (m) : 10 ^-3 or ÷1,000
micro (µ) : 10 ^-6 or ÷1,000,000
nano (n) : 10 ^-9 or ÷1,000,000,000
pico (p) : 10 ^-12 or ÷1,000,000,000,000
