What Is a Third of 1½ Teaspoons?
A third of 1½ teaspoons is ½ teaspoon.

How to measure ½ teaspoon
- With standard cups & spoons: 1/2 tsp
- By volume: 2.5 ml, or 0.08 fluid ounces — handy if you have a measuring jug.
- By weight (most accurate): see the gram table below for common ingredients.
Spoon measurements scale on a simple ladder: 1 tablespoon = 3 teaspoons, and 1 teaspoon = 2 half-teaspoons = 4 quarter-teaspoons. So a third of 1½ teaspoons works out to 1/2 tsp — every part of it comes straight from a standard measuring spoon set.
