In order to answer this I will need more information. I would need to know the size of each pill.
18 grams = 18,000 mg 18,000 / 500 = 36 pills
24.
600 mg = 0.6 grams, so you can divide 25 / 0.6
1 gram = 0.001 milligrams so 0.125 grams = 125 milligrams. So you need 125 pills.
Pills come in many sizes
225 80 mg pills. There are 1000mg in one gram. So it depends on the strength of the pills. It's simple math.
1 gram is equal to 1000 mg, so it would take 8 pills.
Two.
Four. There are 1000 milligrams per gram. If you need two grams, that will equal 2000 milligrams. Divide 2000 by 500 to get four.
Pills come in different sizes.
28.34 grams equal an ounce.
The abbreviation g stands for grams, therefore it is equal to 12345 grams.
