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 $1/undefined$, $1/undefined$, or even $1/24$ teaspoon, but there is no generally accepted standard.
