Re: how many drops in milliliter?

In cooking, a drop is about 0.051 milliliter, specifically it is 1/96th of a teaspoon.

In pharmacies, a drop used to be another name for a minim, which would make it 0.0616 milliliters.

But now the drop is standardized in the metric system to equal exactly 0.05 milliliters.

Re: how many drops in milliliter?

In pharmaceutical applications, 1 drop = 1 minum.

Not in cooking though.

If it is water, the standard was changed 15 - 20 years ago to make 20 drops = 1mL. The viscosity of most things is temperature dependent, so this would be at room temperature. Hope this helps.

Re: how many drops in milliliter?

Drop (unit)
For other uses, see Drop.
The drop is a unit of measure of volume, the amount dispensed as one drop from a dropper. It is often used in giving quantities of liquid drugs to patients, and occasionally in cooking.

The volume of a drop is not well-defined: it depends on the device and technique used to produce the drop and on the physical properties of the fluid. This is similar to units like the cup, tablespoon, and teaspoon that depend on the spoon or cup.

There are several exact definitions of a "drop":

the "metric" drop, 1/20 mL (50 μL).
the medical drop, 1/12 mL (83 1/3 μL).
the Imperial drop, 1/36 of a fluidram (1/288 of an Imperial fluid ounce, or 1/1440 of a gill) (approximately 99 μL).
an alternate, possibly apocryphal, definition of the drop is 1/1824 of a gill (approximately 78 μL).
the U.S. drop, 1/60 of a teaspoon or 1/360 of a U.S. fluid ounce (approximately 82 μL).
an alternate definition of the U.S. drop is 1/76 of a teaspoon or 1/456 US fl oz (approximately 65 μL).
According to Webster dictionary, "drop" indicates the smallest volume of a liquid that may be measured. The size of drop may vary with the viscosity of the liquid.

In the past, a drop was another name for a minim. This meaning was used in Pharmacy to describe a volume equal to one 60th of a fluid dram or one 480th of a fluid ounce. This is equal to about 0.0616mL (U.S.) or 0.0592mL (Britain). Pharmacists have since moved to metric measurements, with a drop being rounded to exactly 0.05mL (that is, 20 drops per millilitre). In hospitals, intravenous tubing is used to deliver medication in drops of various sizes ranging from 10 drops/mL to 60 drops/mL. A drop is abbreviated gt, with gtt used for the plural. These abbreviations come from the Latin for drop, gutta.[1] articles.

A drop can also be used less formally as a unit of volume in recipes. According to some older kitchen references, 24 drops = ¼ teaspoon. Using U.S. definitions, this makes the drop equal to about 0.051mL, making it quite comparable to the pharmacist's drop.[1]
