20 drops = 1.000 mL

  • With the standard dropper standard, one drop is 0.05000 mL (20 drops per mL).
  • 20 drops converts to 1.0000 mL using this dropper standard.
  • Real drop size varies by liquid viscosity, temperature, and dropper angle. For clinical accuracy, always use calibrated equipment.

Next stepIf you are working with essential oils or European Pharmacopoeia medicines, switch the dropper type for a more accurate result.
