About these units
Wine Bottle (btl)
The standard wine bottle holds 750 mL, about 25 US fluid ounces.
Standardisation of the 750 milliliter bottle is recent. Wikipedia does not explain why that figure was chosen, only that it has become the standard unit for wine sales. In the United States, bottles before 1979 followed the fifth, one fifth of a US gallon, about 757 mL. In 1979 the US adopted metric sizes for wine and spirits, making the basic bottle 750 mL as in Europe.
Larger formats are counted in multiples of this bottle: a magnum is two, a double magnum four and a Methuselah eight, while smaller ones include the half bottle of 375 mL and the 187.5 mL piccolo. A 750 mL bottle is exactly three quarters of a liter, roughly 25.4 US fluid ounces. Because the number is set by law for trade, a bottle sold today is the same size in Bordeaux, Napa or Sydney, whatever the shape of the glass.
1 wine bottle = 0.75 liters (exactly).

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).
