Usually the question of how many drops in 1 ml,occurs in those who were prescribed to take a certain medicine in milliliters, while in the packaging there is no corresponding dispenser. But for different solutions the amount of droplets can vary, it will depend on the composition of the liquid, its density, on the surface tension, on the external forces and on the diameter of the tube from which they drip. Therefore, it is impossible to say unequivocally how many drops in ml.
If the kit does not contain a medicinal product,there is a measuring cup or a pipette indicating the number of ml of the medicine purchased, these data are not indicated in the instructions to the preparation, then it is best to measure the necessary quantity with a conventional syringe. When you need to measure more than 1 ml, you can use a normal 2 or 5-cc syringe, and to measure a smaller volume or need to determine exactly how many drops per ml, it is better to take an insulin syringe, the volume of which is 1 ml, with clearly designated decimals .
50 drops - 1 ml;
15 drops - x ml,
We get 15k * 1ml / 50k = 0.3ml.This means to get 15 droplets, you need to get into the syringe 0.3 ml of the solution, but before the first method it is better to separately recalculate how many drops you will get from the volume you have collected. Perhaps you were mistaken in calculating how many drops in 1 ml. This method of calculation is suitable for any type of liquid, with its help you can measure any number of drops, no matter how many fit in one milliliter. This method is very convenient, for the next dose of medication you do not have to recalculate the drops, just type the desired volume into the syringe and drink it.
If you need translation, how many in 1 gr. ml, it is worth considering that the weight will depend on the density of the substance. So, 1 gram of water corresponds to one milliliter, but 1 ml of alcohol is 0.88 grams.
