How the dilution math works
Reconstitution math starts by converting milligrams to micrograms. Since one milligram equals 1,000 micrograms, the total vial amount is multiplied by 1,000. That total is then divided by the amount of diluent added in milliliters.
With a U-100 insulin syringe, 100 units equals 1 mL. Once the concentration is known, the tool calculates how many micrograms are represented by each unit and how many units correspond to the entered reference amount.
