How to Convert Drop to Liter
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) = 0.00005 Liter (L).

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 Liter (L)
Definition
The liter is a metric unit of volume equal to 1,000 cubic centimeters (1 dm³), used worldwide for measuring liquid volumes.
Mathematical Relationship
1 L = 1 dm³ = 10⁻³ m³ = 1,000 mL = 1,000 cm³. One cubic meter contains 1,000 liters.
Conversion Formula
To gallons (US): multiply by 0.264172. To quarts (US): multiply by 1.05669. To fluid ounces (US): multiply by 33.814.
Practical Applications
Fuel volumes, milk/juice containers, water bottles, engine oil, swimming pool volumes, and cooking.
Interesting Facts
One liter of water weighs almost exactly 1 kilogram. The word 'liter' comes from an old French unit called the 'litron' (about 0.831 L).
Common Mistakes
Assuming 1 liter = 1 US quart — a liter is slightly larger (1 L ≈ 1.057 qt). Also, confusing 'L' with 'lb' (pound).
Educational Tips
A liter is a little over a US quart. A 2-liter soda bottle and a 1-liter water bottle are great visual references.
