answer:There is no conversion. The pill form will contain a certain milligram, and your dose will depend on how many pills you are directed to take. If you take a 10mg pill, you receive a dose of 10mg. If you take a 12mg pill, you receive a dose of 12mg. An IV dose will have a concentration (milligrams per milliliter) and a volume (milliliters). Those two numbers will tell you what dose you are getting. For example, if the concentration of the drug is 2mg/ml and you receive 5mls, then your dose is 10mg. If the concentration is 2mg/ml and you receive 6mls Iv, then your dose is 12mg. According to this information, the typical concentration of a solution used for injection seems to be 0.2mg/ml. I don’t work in the human field, so I cannot attest to the accuracy of the information.
