• Volume: A teaspoon is a smaller unit of measurement compared to a tablespoon. In the United States, a teaspoon is equal to approximately 4.93 milliliters (ml) or 0.17 fluid ounces (fl oz). On the other hand, a tablespoon is larger, equal to approximately 14.79 ml or 0.50 fl oz.

• Usage: Teaspoons are typically used to measure smaller amounts of ingredients, such as spices, extracts, or small quantities of liquids. They are commonly used in recipes that require precise measurements, especially for ingredients that can strongly impact the taste, like salt, baking powder, or vanilla extract. Tablespoons, due to their larger size, are used for measuring larger quantities of ingredients, such as liquid ingredients, oils, or certain dry ingredients like sugar or flour.

It's worth noting that teaspoon and tablespoon measurements may vary slightly depending on the region. In some countries, like the United Kingdom, Australia, and Canada, the metric measurements for these units differ. For example, in the UK, a teaspoon is 5 ml, while a tablespoon is 15 ml.

To ensure accuracy in your recipes, it's always best to refer to the specific measurements mentioned in the recipe or use a standard measuring spoon set to avoid confusion or inconsistencies.
