How to Convert Drop to Milliliter
To mL: multiply by 0.05 (approximate). To µL: multiply by 50. 20 drops ≈ 1 mL for aqueous solutions.
1 drop ≈ 0.05 mL = 50 µL ≈ 1/20 mL. Approximately 20 drops = 1 mL (for water-like liquids).
For example, 1 Drop (gtt) = 0.05 Milliliter (mL).

About Drop (gtt)
Definition
The drop (medical/pharmacological) is an approximate unit of volume equal to about 0.05 milliliters, or 50 microliters.
Mathematical Relationship
1 drop ≈ 0.05 mL = 50 µL ≈ 1/20 mL. Approximately 20 drops = 1 mL (for water-like liquids).
Conversion Formula
To mL: multiply by 0.05 (approximate). To µL: multiply by 50. 20 drops ≈ 1 mL for aqueous solutions.
Practical Applications
Eye drop medication, ear drops, essential oil use, flavoring extracts in cooking, and IV drip rate measurement.
Interesting Facts
The size of a drop varies significantly: water drops from a glass dropper (~50 µL) differ from rain drops (~50,000–100,000 µL) by a factor of 1,000.
Common Mistakes
Assuming all drops are the same size — oily liquids produce larger drops than water. Always check the dropper calibration.
Educational Tips
20 drops ≈ 1 mL for water-based solutions. In IV therapy, standard drip sets deliver 10, 15, or 20 drops/mL depending on the design.
About Milliliter (mL)
Definition
The milliliter is a unit of volume equal to one thousandth of a liter (10⁻³ L), exactly equal to one cubic centimeter.
Mathematical Relationship
1 mL = 10⁻³ L = 1 cm³ = 1 cc = 1,000 µL. There are 1,000 mL in one liter.
Conversion Formula
To liters: divide by 1,000. To fluid ounces (US): multiply by 0.033814. To teaspoons (US): multiply by 0.202884.
Practical Applications
Medicine dosing, cooking measurements, beverage volumes (e.g., 330 mL soda can), and cosmetic product sizing.
Interesting Facts
A standard soda can holds 330–355 mL. A shot glass holds about 44 mL. One mL of water weighs exactly 1 gram at 4 °C.
Common Mistakes
Confusing mL with mg (volume vs. mass). Also, 1 mL of oil or alcohol does NOT weigh 1 gram — only water does (at 4 °C).
Educational Tips
1 teaspoon ≈ 5 mL, 1 tablespoon ≈ 15 mL. These are the best kitchen anchors. A standard medicine syringe holds 5 mL.
