About these units
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).

Pinch (pinch)
Traditionally what you can hold between thumb and forefinger; the conventional measure is 1/16 of a teaspoon (about 0.31 mL).
Whatever two fingers can grip, the old definition went: a pinch is the amount of a dry ingredient such as salt, spice or sugar that can be taken between the thumb and forefinger. Nothing official fixes it, so the size depends on the hand, the ingredient and the cook. Sources differ even on the convention. Some measuring spoon makers and American cookbooks use one sixteenth of a US teaspoon, while others give one eighth or one twenty-fourth.
The figure used here is one sixteenth of a US teaspoon, about 0.31 mL, which makes a pinch half a dash and twice a smidgen. Wikipedia's cooking measures table prints a smaller 0.23 mL for the same fraction because it derives it from a fluid ounce fraction that does not agree with its teaspoon fraction. The British tradition is larger, with a pinch set at a quarter of a UK teaspoon, roughly 0.89 mL according to the Wikipedia article on the pinch. Sizes are conventional, and a pinch measured on a scale would vary from one try to the next.
1 pinch = 0.0003080575996 liters (approximately).
