Pinch (unit)
A pinch is a small, indefinite amount of a substance, typically a powder like salt, sugar, spice, or snuff. It is the "amount that can be taken between the thumb and forefinger".
Some manufacturers of measuring spoons and some U.S. cookbooks give more precise equivalents, typically 1/16 US customary teaspoon; some sources define it as 1/8 or 1/24 teaspoon. There is no generally accepted standard.

In the United Kingdom, a pinch is traditionally 1/2 UK salt spoon, the equivalence of 1/4 UK teaspoon. 1/2 UK salt spoon is an amount of space that can accommodate 15 British imperial minims (1/4 British imperial fluid drachm or 1/32 British imperial fluid ounce; about 14·41 US customary minims (0·24 US customary fluid dram or 0·03 US customary fluid ounce) or 0·89 millilitres) of liquid.
