About these units
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).

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).
