Assuming a drop of water, it's about 50,000 micrograms (or 50 milligrams)
It depends on the drop factor of the particular dropper that you are using. The volume of 30 drops can vary depending on the drop size. Generally, for water, 20 drops is approximately equal to 1 milliliter.
16 drops of water or any water soluble substance makes 1 ml
1 milliliter (mL) is equal to 1000 microliters (uL).
There are approximately 200 drops of water in 1 ml, so in 10 ml there would be around 2000 drops.
Approximately 20 drops of liquid are equivalent to 1 milliliter.
Approximately 16 drops is equal to 0.8 ml.
1 ml = 1000 microliter
If the drop is considered equal to 0,05 mL the answer is 0,35 mL.
1000 ml makes 1litre
56 drops is 2.8mL
20 drops = 1ml 20 drops = 1cc 1ml = 1cc
Each dose from a 15 ml container would be 4 ml (15 ml / 60 doses). Given that 1 ml equals 32 drops, each dose would contain 128 drops (4 ml * 32 drops).
Eight mL is 160 drops.
120 drops. 20 drops / mL.
There are approximately 240 drops in 10 ml. Therefore 2.5 ml contains about 60 drops.
~60 drops solution: 20 drops/mL * 3 mL = 60 drops
Each dose would be 2.5 ml, which means each dose would require 80 drops (2.5 ml * 32 drops/ml).
