How to Convert Drop to Barrel (UK)
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) = 3.055128e-7 Barrel (UK) (bbl (UK)).

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 Barrel (UK) (bbl (UK))
Definition
The UK (imperial) barrel is a unit of volume equal to 36 imperial gallons, or approximately 163.659 liters.
Mathematical Relationship
1 UK barrel = 36 UK gal = 288 UK pt = 5,760 UK fl oz ≈ 163.659 L ≈ 1.637 hL.
Conversion Formula
To liters: multiply by 163.659. To UK gallons: multiply by 36. To US barrels: multiply by 1.373.
Practical Applications
Historical UK brewing trade, legacy contracts and legal references, and traditional measurements in some industries.
Interesting Facts
The UK barrel (36 imp gal ≈ 164 L) is different from both the US liquid barrel (31.5 US gal ≈ 119 L) and the oil barrel (42 US gal ≈ 159 L).
Common Mistakes
Confusing UK, US, and oil barrels — they are all different sizes. Always specify the barrel type.
Educational Tips
A UK barrel = 36 imperial gallons ≈ 164 liters. Remember: there are at least 3 common barrel sizes — UK, US, and oil.
