How many drops are in 1 mL if the drop factor is 20 drops/mL?

When the drop factor is given as 20 drops per mL, this means that for every milliliter of fluid, there are 20 individual drops produced. The drop factor essentially defines the volume of liquid that corresponds to each drop, establishing a direct relationship between milliliters and the number of drops. Therefore, since you are specifically looking for the number of drops in 1 mL, the answer is directly derived from this ratio: there are indeed 20 drops in 1 mL when the drop factor is 20 drops/mL. This clarity on the drop factor allows for accurate administration of medications or fluids, highlighting the importance of understanding how to convert between these measurements in dosage calculations.
