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) = 0.00281560068 Tablespoon (UK) (tbsp (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 tablespoon is a unit of culinary volume equal to approximately 17.758 milliliters, or 3 UK teaspoons.
1 UK tbsp ≈ 17.758 mL = 3 UK tsp. About 20% larger than a US tablespoon (14.787 mL).
To mL: multiply by 17.758. To US tablespoons: multiply by 1.201. To metric tablespoons: multiply by 1.184.
Traditional British baking and cooking, Commonwealth recipes, and older pharmaceutical references.
Australia officially uses a 20 mL tablespoon, the UK uses ~17.8 mL, and the US uses ~14.8 mL — three different sizes for the same name!
Mixing up UK and US tablespoons in international recipes. A UK tbsp is ~20% larger than a US tbsp.
Modern UK cooking is shifting to metric (15 mL). When following old UK recipes, add ~20% more than a US tbsp would indicate.
