What is the best estimate for liquid volume of a drop food coloring?

The average volume of a drop of food coloring is approximately 0.05 milliliters (mL) or 50 microliters (µL).

This value can vary slightly depending on the specific food coloring brand, the type of dropper used, and other factors such as temperature and viscosity.

Some food coloring brands specifically provide information about the volume of a drop, while others may require experimental measurement or estimation based on the dropper's specifications.
