One and a half (1.5) teaspoons is the equivalent of one fourth (.25) fluid ounces. But since you didn't specify if you meant how much in volume or weight, I had to go with fluid ounces. If you wanted grams, then there is no formula to calculate a conversion of weight to volume, especially since ingredients have different weights.
