Weight (kg) x dosage (kg) = required dosage

Amount in IV fluid

(Concentration% / 100) x volume [mL] = dosage amount [g]

Basic dosage calculation

(Desired dose/amount on hand) x volume = dose [units/mL]

IV drop rate formula

(Volume [mL] / time[min]) x drop factor [gtts/min]= flow rate [gtts/min]

IV mL rate formula

(Volume [mL] / time[hr]= flow rate [mL/hr]
