What is a US fluid ounce?

A US fluid ounce is a unit of volume in the US customary system equal to exactly 29.5735295625 milliliters, commonly used for measuring small liquid volumes in the United States.

What is meant by a drop as a unit of volume?

A drop is an informal, non-SI unit representing the volume of a single liquid droplet, typically approximated as about 0.05 milliliters in medical and pharmaceutical contexts.

Why might drop volumes vary in practical use?

Drop volumes vary due to differences in liquid properties and dispensing geometry, meaning that the volume of each drop is not fixed and can differ depending on conditions.
