How to Convert Drop to Nanoliter
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) = 50000 Nanoliter (nL).

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 Nanoliter (nL)
Definition
The nanoliter is a unit of volume equal to 10⁻⁹ liters, or one billionth of a liter.
Mathematical Relationship
1 nL = 10⁻⁹ L = 10⁻⁶ mL = 1,000 pL = 10⁻³ µL. One microliter = 1,000 nL.
Conversion Formula
To microliters: divide by 1,000. To picoliters: multiply by 1,000. To liters: multiply by 10⁻⁹.
Practical Applications
Micro-dosing drug compounds, DNA micro-array printing, micro-fluidic diagnostic chips, and nano-dispensing robots.
Interesting Facts
Some advanced liquid handlers can dispense volumes as small as 2.5 nL with high accuracy, enabling drug discovery at microscale.
Common Mistakes
Confusing nL with mL — there are one million nL in a single mL. Always double-check prefix meanings.
Educational Tips
Nanoliter = one millionth of a mL. Think of it as a tiny drop invisible to the eye — about the volume of a cube 100 µm on each side.
