How to Convert Drop to Picoliter
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) = 50000000 Picoliter (pL).

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 Picoliter (pL)
Definition
The picoliter is a unit of volume equal to 10⁻¹² liters, or one trillionth of a liter.
Mathematical Relationship
1 pL = 10⁻¹² L = 10⁻⁹ mL = 1,000 fL = 10⁻⁶ µL. One nanoliter = 1,000 pL.
Conversion Formula
To liters: multiply by 10⁻¹². To nanoliters: divide by 1,000. To femtoliters: multiply by 1,000.
Practical Applications
Inkjet printer droplet volumes (1–80 pL), PCR reaction miniaturization, and micro-array spotting.
Interesting Facts
A standard inkjet printer deposits droplets of 1–10 pL. Some advanced printers use 1.5 pL droplets for high-resolution photos.
Common Mistakes
Confusing pL with µL (microliter) — there are one million pL in a single µL.
Educational Tips
Picoliter is the realm of inkjet drops and micro-fluidic reactions. 1 pL = a cube about 10 µm on a side — cell-sized.
