Unit Conversion calculators
This calculator converts a volume in tablespoons to fluid ounces using the exact ratio: divide the tablespoon value by 2. One US tablespoon is defined as exactly one 256th of a US gallon, and one fluid ounce as exactly one 128th of a gallon, so this conversion carries no rounding at all.
Recipes that build up in tablespoons, especially for sauces, dressings, and small-batch liquids, are often easier to measure or compare once converted into fluid ounces, the unit most liquid ingredients are labeled with on packaging. This page covers the liquid, fluid ounce measurement, not the dry ounce, a weight unit that depends on ingredient density.
For the reverse direction, converting fluid ounces back into tablespoons, or converting a tablespoon value into cups or teaspoons instead, see the related converters below.

The Tablespoons to Fluid Ounces Formula
To convert tablespoons to fluid ounces, divide the tablespoon value by 2. For example, 5 tablespoons divided by 2 equals 2.5 fl oz.
To go the other way, use the Fluid Ounces to Tablespoons converter instead, which multiplies by 2 for you. For a tablespoon value that needs to become teaspoons, see the Tablespoons to Teaspoons converter below.
Why a Fluid Ounce Equals Exactly 2 Tablespoons
A US fluid ounce is defined as exactly 1/8 of a cup and a tablespoon as exactly 1/16 of a cup, so a fluid ounce holds exactly 2 tablespoons. Equivalently, both units trace back to the same US gallon, which is why the 2:1 ratio carries no rounding error at all.
This Is Specifically the Fluid Ounce, Not the Dry Ounce
"Tbsp to oz" can be ambiguous in everyday recipe language, the same way "cups to oz" is. This calculator uses the fixed fluid ounce ratio, correct for liquids. A dry ounce is a weight measurement that depends on the ingredient's density, so a tablespoon of a dry ingredient will weigh a different number of dry ounces depending on what it is.
For ingredients measured by the spoon, the Tablespoons to Grams Converter gives the weight of a tablespoon of water, milk, flour, sugar, honey, or butter. A fluid ounce measures volume and a pound measures weight, so the Fluid Ounces to Pounds Converter uses the ingredient's density to connect the two. Butter is also sold in sticks, so the Butter Converter switches between cups, sticks, tablespoons, and grams.
