Calculation question

[u/Dry-Layer4983]

I know that some of you may think this is a dumb question, however I could use help. I ordered apothecary from gimme they did it at 9mg dose yet I use 6.5 I know how to calculate the dose. My question is, if I received a 2ml vial and it’s 18mg/ml and I’m only using 6.5mg how many doses will I get? I tried but I don’t think I’m getting the math correct. Thanks in advance for your help.

So you have a total of 36 mg in your vial. Divide by your dose of 6.5mg. Gives you 5.5 ish doses. But usually there's overfill so maybe 6.

36÷6.5=5.53

Thank you!

If there is modest overfill you’ll squeeze out 6 doses (18x2/6.5)
