half ounce = how many teaspoon
Best Answer: Just so you know, ounce is a unit of weight. Fluid ounce is a unit of volume. 2 Tbsp = 1 fluid ounce. 3 tsp = 1 Tbsp. So 3 tsp = 1/2 fluid ounce. If you want to convert teaspoons to ounces (weight), you'll have to know the density of the item in order to do the conversion. There a lot of good websites that have programs that can do this.
