the first and most important thing any engineer or technician (or anyone living in the modern world) is learn the prefixes for the metric system. The basic ones are very simple.





da (deca) = x10


k (kilo) = x1000


M (Mega) = x1000000


G (Giga) = x1000000000


T (Tera) = x1000000000000





d (deci) = /10


c (cent) = /100


m (milli) = /1000


碌 (micro) = /1000000


n (nano) = /1000000000


p (pico) = /1000000000000How do you figure out how many grams AND milligrams this is?
1mcg = 1/1,000,000 grams.


300mcg = 300 / 1,000,000mcg/g = 0.000300 grams.





1mg = 1/1,000 grams.


300mcg = 300 / 1,000mg/g = 0.300mg.





3.0mg = 3.0mg.


3.0mg / 1,000mg/g = 0.003g.
