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) = 0.001759753986 Fluid Ounce (UK) (fl oz (UK)).

The drop (medical/pharmacological) is an approximate unit of volume equal to about 0.05 milliliters, or 50 microliters.
1 drop ≈ 0.05 mL = 50 µL ≈ 1/20 mL. Approximately 20 drops = 1 mL (for water-like liquids).
To mL: multiply by 0.05 (approximate). To µL: multiply by 50. 20 drops ≈ 1 mL for aqueous solutions.
Eye drop medication, ear drops, essential oil use, flavoring extracts in cooking, and IV drip rate measurement.
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.
Assuming all drops are the same size — oily liquids produce larger drops than water. Always check the dropper calibration.
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.
The UK fluid ounce is a unit of liquid volume equal to 1/160 of an imperial gallon, or approximately 28.413 milliliters.
1 UK fl oz = 1/20 UK pt = 1/160 UK gal ≈ 28.4131 mL. It is about 4% smaller than a US fluid ounce.
To mL: multiply by 28.4131. To US fl oz: multiply by 0.96076. To UK pints: divide by 20.
Older UK recipes, some beverage labels in Commonwealth countries, and traditional pharmaceutical dosing.
Paradoxically, the UK fluid ounce is smaller than the US fluid ounce (28.41 vs. 29.57 mL), even though UK pints and gallons are larger.
Assuming UK and US fluid ounces are the same — they differ by about 4%. This seems small but accumulates in recipes.
UK fl oz ≈ 28.4 mL, US fl oz ≈ 29.6 mL. The UK has more fl oz per pint (20) vs. US (16), but each UK fl oz is smaller.
