Question: is 5mg the same as 5ml?
Answer: mL is a measurement of volume, while mg is a measurement of mass. ... For instance, if you have a solution that contains 10mg of medication in 5mL and you want to give 5mg of medication, then “give over have” or 5/10 or one half, so half of 5mL is 2.5 mL. 2.5 mL of the solution will contain 5mg of the medication.
