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 Fluid Ounce (fl oz)
One 128th of a US gallon, 29.5735 mL. Not the same as the weight ounce, and about 4% larger than the imperial fluid ounce.
Fluid ounce began as an attempt to link volume to weight: the volume occupied by one ounce of some substance, such as wine in England or water in Scotland. Definitions varied by region and by liquid. When Britain defined its imperial gallon in 1824 as the space of ten pounds of water, the imperial fluid ounce came out so that an ounce of water weighs about one avoirdupois ounce. The US fluid ounce followed a different path and comes from the older wine gallon.
The US fluid ounce is exactly 1/128 of a US gallon, 29.5735295625 milliliters, about 4 percent bigger than the imperial one at 28.4130625 milliliters. American nutrition labels use yet another figure, treating one fluid ounce as 30 milliliters, a convenient rounding for serving sizes. The name is a trap, because a fluid ounce measures space while a weight ounce measures mass. A US fluid ounce of water weighs a bit more than an ounce of weight, while a fluid ounce of honey weighs considerably more.
1 US fluid ounce = 0.02957352956 liters (approximately).
