Giving some precision to the imprecise -[ HMM ]-

Measuring spoon handles. The spoons are part of a set including conventional teaspoon (5ml) and tablespoon (15ml) sizes, plus fractions of a teaspoon. I've never had to use any of the minuscule informal measurements in this range, but I am amused that someone attempted to standardize these rather vague units called for in recipes.

 

According to one source I've found, here are the equivalents to each unit:

 

Tad: 1/8 teaspoon (0.6ml)*

Dash: 1/8 to 1/16 teaspoon (0.6 to 0.3ml)

Pinch: 1/16 to 1/24 teaspoon (0.3 to 0.2 ml)

Smidgen: 1/32 to 1/48 teaspoon (less than 0.2 ml)

 

* My set includes a 1/8-tsp spoon, which means the Tad spoon in the set is probably closer to 1/10 teaspoon.

 

I'm sure the — excuse the pun — well-seasoned professional or hobbyist will take these measurements with, well, a grain of salt and adapt accordingly to achieve repeatable perfection.
