One drop from an eyedropper typically measures about 0.05 milliliters (ml). However, this can vary depending on the size and design of the dropper, as well as the liquid’s viscosity.
Here’s a general range:
1 ml = approximately 20 drops.
Therefore, 1 drop ≈ 0.05 ml.
If precision is important, you may want to measure it using a calibrated dropper or syringe.
