Usually, the question of how many drops in 1 ml arises for those who are prescribed to take a certain medicine in milliliters, while there is no corresponding dispenser in the package. But for different solutions, the number of drops may vary, it will depend on the composition of the liquid, its density, surface tension, external forces acting and the diameter of the tube from which they drip. Therefore, it is impossible to say unequivocally how many drops in ml.

Back in the days of the Soviet Union, a table was created that indicated the number of drops for different liquids, including medicinal solutions. So, if in 1 ml of distilled water there are only 20 drops, then in the same volume of wormwood tincture - 56, and medical ether - 87. One drop of ordinary water is about 0.03-0.05 ml, an alcohol-containing solution - 0.02 ml.

If the medicine does not come with a measuring cup or pipette indicating the number of ml of the purchased medicine, these data are not indicated in the instructions for the drug, then it is best to measure the required amount with a regular syringe. When neededto measure more than 1 ml, you can use a regular 2 or 5 cc syringe, and for measuring a smaller volume or need to find out exactly how many drops in 1 ml, it is better to take an insulin syringe that has a volume of 1 ml, with clearly marked decimal divisions.

If you need to drink a certain number of drops, and there is no drop dispenser or pipette included with the medicine, you can simply draw 1 ml of the solution into the insulin syringe and measure how many drops are in 1 ml. Based on the data obtained, you can already find out how many tenths of a ml you need to draw into the syringe in order to get the right number of drops. For example, you need to take 15 drops of a certain medicine. Having typed 1 ml into an insulin syringe without a needle, carefully scoop out its contents, while counting the number of drops. Let's say that you got 50 drops for this volume of medicine. By drawing up a simple proportion:

50 drops - 1 ml;

15 drops - x ml, We get 15k1ml / 50k=0.3 ml. This means that in order to get 15 drops, you need to draw 0.3 ml of the solution into the syringe, but before the first dose, it is better to separately count how many drops you get from the volume you have dialed. You may have made a mistake when calculating how many drops are in 1 ml. This calculation method is suitable for any type of liquid, it can be used to measure any number of drops, regardless of how many of them fit in one milliliter. This method is very convenient, for the next medication you do not have to recalculatedrops, just draw the right amount into the syringe and drink it.

It is also quite convenient to give water to small children in this way: it is better for them to insert the syringe directly into their mouth, directing the flow of liquid not into the throat, but over the cheek. So the baby will not be able to spit out the medicine and will not choke. If the dosage of the drug is more than 5 ml, then it is more convenient to use not a syringe, but cutlery for its use. So, in an ordinary teaspoon is placed 5 ml of liquid, and in the dining room - 15.

If necessary, how much in 1 gr. ml, it should be borne in mind that the weight will depend on the density of the substance. So, 1 gram of water corresponds to one milliliter of it, but 1 ml of alcohol is 0.88 grams.
