Understanding the Relationship

To determine how many drops are in a milliliter, we use the formula: X drops × 0.05 gtt = 1 ml. Alternatively, dividing 1 ml by 0.05 gives us the answer: 20 gtt is equivalent to 1 ml.

Conversion Formula

One drop is equal to 0.05 ml. Therefore, to find milliliters from drops, multiply the number of drops by 0.05: (20 × 0.05) gtt = 1 ml.
