There are 6 teaspoons in 1 fluid ounce (US).
Explanation:
- 1 US fluid ounce = 2 tablespoons
- 1 tablespoon = 3 teaspoons
- Therefore, 1 fluid ounce = 2 × 3 = 6 teaspoons
If you are referring to weight ounces (dry ounces), the conversion depends on the ingredient's density, so it's not a fixed number. But for liquid measurements, 6 teaspoons per fluid ounce is standard.
