I don't understand how to do this and frankly I am going to fail unless someone can explain it in really simple terms please and thank you.

.015g x 1000mg/1g = 15 mg
since 1000 mg = 1 gram, it's liking multiplying by 1, but it lets you cancel the grams and leave the milligrams.

In the metric system all prefixes are based on powers of 10. Thus 20 mm = 2 cm = .02 m.
Try this: ?mg = 0.015 g (1000 mg/1 g) The g's cancel and the math says to multiply 0.015 * 1000 = 15.0 mg.
This is called dimensional analysis. Using it you can do ANY conversion.

0.015g = 15 mg
1g x 1000 = 1000 mg

hahaha its 15 mg
milli means 1/1000 of a gram. so just move the decimal point three spaces.

1 g = 1000mg
.015*(1g)=1000(mg/g)*(.015g)
= 15mg

1g = 1,000mg...Therefore grams x 1,000 = milligrams
0.015g x 1,000mg/g = 15mg (g cancels).
