Why does the volume of a drop vary?

The size of a drop depends on the liquid's properties like viscosity and surface tension, as well as the method used to dispense it, resulting in variability.

Is this conversion precise for medical dosing?

While useful for estimation, drops are informal units and should be used cautiously for dosing, recognizing variations in drop size.

What is the difference between the standard and legal US cup?

The standard US cup equals approximately 236.588 mL, while some nutritional labeling uses a 'legal' cup defined as 240 mL, which can slightly affect conversions.
