How much is a dash or a pinch when COOKING?

Traditionally, a “pinch” simply meant the amount you could literally pinch between your forefinger and thumb, which usually falls somewhere between 1/16 and 1/8 of a teaspoon. A smidgen is half a pinch (1/32 of a teaspoon), and a dash is a liquid measurement that translates to to 1/8 of a teaspoon.

all of them except "c"
