How to Convert Drop to Barrel (Oil)
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) = 3.144905e-7 Barrel (Oil) (bbl (oil)).

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 (Oil) (bbl (oil))
Definition
The oil barrel is a unit of volume equal to 42 US gallons (approximately 158.987 liters), the standard for measuring crude oil and petroleum products.
Mathematical Relationship
1 oil barrel = 42 US gal = 158.987 L = 34.97 UK gal = 5,376 US fl oz.
Conversion Formula
To liters: multiply by 158.987. To US gallons: multiply by 42. To cubic meters: multiply by 0.158987.
Practical Applications
Crude oil trading and pricing, refinery throughput, national oil production statistics, and petroleum reserve reporting.
Interesting Facts
Global oil consumption is about 100 million barrels per day. Oil is no longer actually shipped in barrels — the unit persists purely as a standard of measurement.
Common Mistakes
Confusing the oil barrel (42 gal) with the US liquid barrel (31.5 gal). Always use 'bbl (oil)' or specify the type.
Educational Tips
Oil is priced per barrel (~42 gallons). When you see '$70/barrel,' that means about $1.67/gallon before refining and distribution costs.
