How to Convert Drops to Milliliters

To convert a measurement in drops to a measurement in milliliters, divide the volume by the following conversion ratio: 20 drops/milliliter.

Since one milliliter is equal to 20 drops, you can use this simple formula to convert:

milliliters = drops ÷ 20

The volume in milliliters is equal to the volume in drops divided by 20.

For example, here's how to convert 5 drops to milliliters using the formula above.

milliliters = (5 gtt ÷ 20) = 0.25 mL

Drops and milliliters are both units used to measure volume. Keep reading to learn more about each unit of measure.

What Is a Drop?

Drops are an approximate measurement of the amount of liquid dispensed from a dropper. It's important to note that a drop is not a precise volume measurement. Drops are often used to measure medications or cooking ingredients.

Drops can be abbreviated as gtt, and are also sometimes abbreviated as gt. For example, 1 drop can be written as 1 gtt or 1 gt.

What Is a Milliliter?

The milliliter is a unit of volume equal to 1 cubic centimeter, 1/1,000 of a liter, or about 0.061 cubic inches.[1]

The milliliter is an SI unit of volume in the metric system. In the metric system, "milli" is the prefix for thousandths, or 10-3. A milliliter is sometimes also referred to as a millilitre. Milliliters can be abbreviated as mL, and are also sometimes abbreviated as ml or mℓ. For example, 1 milliliter can be written as 1 mL, 1 ml, or 1 mℓ.

Since one milliliter is equivalent to one cubic centimeter, milliliters are sometimes expressed using the abbreviation for a cubic centimeter (cc) for things such as medical dosages or engine displacements.
