What Is a Third of 1 Teaspoon?

A third of 1 teaspoon is ⅓ teaspoon.
Measure it as: 1/4 tsp + 1/8 tsp (rounded to the nearest measurable spoon — level it off slightly generously.)

How to measure ⅓ teaspoon

Spoon measurements scale on a simple ladder: 1 tablespoon = 3 teaspoons, and 1 teaspoon = 2 half-teaspoons = 4 quarter-teaspoons. So a third of 1 teaspoon works out to 1/4 tsp + 1/8 tsp (rounded to the nearest measurable spoon — level it off slightly generously.) — every part of it comes straight from a standard measuring spoon set.
