The conversion of fluid ounces to teaspoons is a common measurement task in cooking and baking. The exact number of teaspoons in 4 ounces depends on the density of the liquid being measured. For water, 4 ounces is equal to 8 teaspoons. For denser liquids, such as oil or honey, 4 ounces will be less than 8 teaspoons.
Knowing the conversion between ounces and teaspoons is important for accurate measurement in recipes. Using the wrong amount of liquid can affect the texture and flavor of the final product. For example, if a recipe calls for 4 ounces of water and you accidentally use 8 teaspoons instead, the batter or dough may be too thin. Conversely, if you use less than 4 ounces of water, the batter or dough may be too thick.
