How do you calculate drug MG?
So, 1 mg is found in 0.5 ml of solution. So, if there is 1 mg of active drug in 0.5 ml, we can multiply 0.5 ml of solution by five to get our answer (as we want 5 mg of the drug). 0.5 multiplied by five is equal to 2 and a half millilitres.

How do you calculate ampules of a drug?
If you have an ampoule of 500mg in 4ml, and you need 200mg, it can appear to be a daunting calculation. The first step is to find out what volume contains 1mg (4/500) and then multiply it by how many mg you want (200). The common error here is to get it upside down, and divide what you’ve got by what you want.
How do you calculate mg per mL?
To find the number of milligrams in a millilitre you need to divide 500mg by 100; 1ml of 0.5% lidocaine contains 5mg per ml.
What is mg/mL concentration?
Milligrams per milliliter (mg/mL) is a measurement of a solution’s concentration. In other words, it’s the amount of one substance dissolved in a specific volume of a liquid. For example, a salt water solution of 7.5 mg/mL has 7.5 milligrams of salt in each milliliter of water.
