Video transcript

To measure 1 mL in a dropper, fill the dropper to the marked 1 mL line. If the dropper isn't marked, count the number of drops it produces per mL, as this varies by dropper size. Typically, 20 drops of water approximately equal 1 mL. Calibration may be needed for different liquids since viscosity can affect drop size.

Questions and answers

  1. How many drops are in 1 mL?

    Typically, there are about 20 drops in 1 mL of water, but this can vary based on the dropper size and liquid viscosity.

  2. What should I do if my dropper isn't marked?

    You can measure 1 mL by counting the number of drops it produces, as each drop's size can differ between droppers.

  3. Does viscosity affect how much liquid is in a drop?

    Yes, the viscosity of the liquid can significantly affect drop size, leading to variations in how much liquid is dispensed.
