how many drops is a ml?

The number of drops in a milliliter (mL) depends on the size of the drops and the viscosity of the liquid. In general, a mL of water is approximately 20 drops. However, this can vary depending on the specific liquid and the size of the drops.

A drop is a unit of volume that is often used to measure small quantities of liquid. It is a non-standard unit of measure that is not formally defined, but is commonly used in medicine, cooking, and other applications.

The size of the drops is determined by the viscosity of the liquid and the size of the dropper or pipette that is used to dispense the liquid. Viscosity is a measure of a liquid's resistance to flow, and liquids with higher viscosity tend to form larger drops when they are dispensed.

In general, smaller drops are more accurate and precise when measuring small volumes of liquid, as they are less likely to vary in size. However, smaller drops may be more difficult to see or count, particularly if the liquid is not clear.

In order to accurately measure the number of drops in a mL, it is important to use a calibrated dropper or pipette and to follow the manufacturer's instructions for proper use and handling. It is also important to measure the drops in a consistent manner, using the same technique and equipment each time.
