How many milliliter is 150mg?

Answer 1

This cannot be answered directly since liter is a measurement of volume and gram is a measurement of weight or mass. However if water at 4 deg C is the reference of what is being measured, then 1 gram = 1 milliliter, therefore 125 mg = .125 ml.

Answer 2

This cannot be sensibly answered. A milliliter (mL or ml) is a measure of volume, kg is a measure of weight or mass.

Answer 3

Depends on the density. 150 mg Mercury wouldn't be as many ml as 150 mg of water.
