How many drops are there in one milliliter?

The correct answer is based on the commonly accepted conversion in pharmacy and medicine, where one milliliter is generally understood to contain approximately 20 drops. This standard is derived from the use of standard dropper equipment and the viscosity of water, which is the most common liquid measured in this manner.

In practical terms, different types of liquids can vary in the number of drops per milliliter due to differences in viscosity and surface tension. However, for the purposes of medication preparation and dosage calculations, 20 drops per milliliter serves as a useful and widely accepted standard that pharmacy technicians use when compounding medications or measuring dosages.

It's important for pharmacy technicians to be familiar with this conversion, as it plays a key role in ensuring dosages are administered accurately and consistently. Understanding this unit of measure helps in effective patient care and medication management.
