Drops ↔ mL Converter (Drop Factor)
Convert between drops and millilitres for eye/oral drops and IV sets using the drop factor.
Drop size isn't standard — it depends on the dropper, the liquid's surface tension and the angle, which is why 'drops/mL' ranges from ~15 to 60. Anchors: a 5 mL eye-drop bottle holds ~100–140 drops. For IV infusions the drop factor is printed on the giving-set packet and is essential for the manual drip-rate calculation. Eye-drop counting helps estimate how long a bottle lasts.
