About these units
Dash (dash)
A quick shake from a bottle; the conventional measure is 1/8 of a teaspoon (about 0.62 mL).
Recipes asking for a dash of bitters or a dash of salt rely on a word that simply means a quick, sudden motion, here a brief shake or splash from a bottle or shaker. There is no legal definition, and Wikipedia's article on cooking weights and measures lists the dash among the drop, smidgen and pinch as the units most commonly understood to be approximate. Early cookbooks relied on such vague amounts until Fannie Farmer pushed exact volume measures in her 1896 book.
Where a number is wanted, the convention is that a dash is one eighth of a US teaspoon, twice a pinch and half a saltspoon. One eighth of a US teaspoon is about 0.62 mL, the figure used here. The same Wikipedia table prints 0.46 mL, which comes from a fluid ounce fraction and does not match its own teaspoon fraction, so that smaller number is best treated as a slip. In real use a dash from a bar bottle depends on the nozzle and the wrist, so the conventional size is only a guide.
1 dash = 0.0006161151992 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).
