US Minims to US Gallons (min to gal)
1 US minim equals 0.00001627604167 US gallons (rounded).
How to convert US minims to US gallons
To convert US minims to US gallons, multiply the number of US minims by 0.00001627604167. The factor is rounded to 10 significant digits. To go the other way, multiply US gallons by 61,440.
US gallons = US minims × 0.00001627604167
Example: 10 US minims = 0.0001627604167 US gallons.
Pints, quarts, gallons and fluid ounces differ between the US and the UK. Units are labeled 'US' or 'imperial' to avoid confusion.
About these units
US Minim (min)
One sixtieth of a fluid dram (about 0.0616 mL), roughly one drop.
A drop is a poor unit of volume, because its size shifts with the liquid's thickness and density. The Royal College of Physicians of London tried to fix that in the 1809 edition of its pharmacopoeia, which introduced the minim as a replacement for the drop. The US minim is 1/60 of a fluid dram and 1/480 of a fluid ounce, exactly 61.611519921875 microlitres, or about 0.0616 mL.
Measuring so little needed special glassware. The minim-tube was a graduated pipette, an idea traced to a design of 1791 by the French chemist François-Antoine-Henri Descroizilles, and a minimometer was another name for such a graduated tube. The British imperial minim is slightly smaller, about 0.0592 mL, and the UK Weights and Measures Act 1963 provided for its abolition, which took effect on 1 February 1971. Today dosing is metric, and a drop-sized quantity is usually stated in microlitres or tenths of a millilitre.
1 US minim = 0.00006161151992 liters (approximately).

US Gallon (gal)
Exactly 231 cubic inches or 3.785411784 liters (128 US fluid ounces). About 17% smaller than the imperial gallon.
The US gallon is a survivor of English wine trade. Around 1706, a statute in Queen Anne's reign fixed the wine gallon at exactly 231 cubic inches, settling confusion among the competing gallons for wine, ale and corn. British colonies in North America used that wine gallon, and in 1824 Britain replaced all its gallons with a new imperial one while the United States kept the old measure. It was adopted as the legal US standard in 1836 and is still defined as exactly 231 cubic inches, or 3.785411784 liters.
That makes the US gallon about 17 percent smaller than the imperial gallon, a difference that explains why American and British fuel-economy figures cannot be compared directly. Everyday uses are milk jugs, paint cans and gasoline pumps. One gallon divides evenly into four quarts, eight pints, sixteen cups and 128 fluid ounces. A gallon of water weighs a little over 8 pounds, an easy figure to remember when loading a car with water jugs.
1 US gallon = 3.785411784 liters (exactly).
