There is half an ounce in each tablespoon. In other words, it takes 2 tablespoons to equal 1 dry ounce. A tablespoon is also equivalent to 3 teaspoons, about 15 milliliters, and between 14 and 15 grams. Two tablespoons, or 1 ounce, also equals 1/8 cup.
Measurement equivalent charts provide easy instructions by which to convert various measurements while cooking. It is important to remember that 1 ounce by American measurement is not the same as 1 ounce in a country that uses the metric system, such as Britain. Finding a chart including both systems allows for the translation of recipes internationally.
