How many fluid ounces is 1 tablespoon?

Half of one exactly: 0.5 fl oz, and the converter prints a clean 0.5 rather than a run of decimals. The amounts asked for next most often: half a tablespoon is 0.25 fl oz, 1.5 tbsp is 0.75 fl oz, 2 tbsp is exactly 1 fl oz, 3 tbsp is 1.5 fl oz, 4 tbsp is 2 fl oz, 6 tbsp is 3 fl oz, 8 tbsp is 4 fl oz, 12 tbsp is 6 fl oz and 16 tbsp is 8 fl oz. Type any of them into the From box and the headline changes without pressing anything.

How many tablespoons are in a fluid ounce?

Two exactly, in US measure. Half a fluid ounce is 1 tbsp, 2 fl oz is 4 tbsp, 4 fl oz is 8 tbsp, and 8 fl oz, which is one US cup, is 16 tbsp. The Swap units button between the two boxes turns this page into a fluid ounces to tablespoons converter without reloading it, and the list under the answer then reads the other way too, with the tablespoon row among the units it prints.

Is this the US tablespoon, the metric one or the Australian one?

Tablespoon (US) here is exactly 14.78676478125 mL, half a US fluid ounce and three US teaspoons. It is the only tablespoon entry. A separately supplied 15 mL tablespoon convention is about 1.4% larger; a supplied 20 mL convention is one third larger than 15 mL. Confirm the source convention instead of inferring it from a country, recipe or spoon. Select Milliliter in From for those supplied volumes: 15 mL displays as 0.507210340528 US fl oz and 20 mL as 0.676280454037 US fl oz.

Does an imperial fluid ounce change the answer?

Yes, by about 4 percent. A US fluid ounce is 29.5735295625 mL against 28.4130625 mL for the imperial one, so measured against the imperial ounce a US tablespoon is 0.520421365393 fl oz rather than a clean 0.5, and 1 imperial fluid ounce is 1.92151988081 US tablespoons rather than 2. Both unit menus carry Fluid ounce (imperial) at all times, so you can select it in the To box; the converter counts it as uncommon, so it only joins the list under the answer once the switch marked Show 5 more is ticked.

How many tablespoons make a cup, and what is a quarter cup?

One exact US cup is 16 US tablespoons or 8 US fluid ounces. Three quarters of a cup is 12 tbsp, half a cup 8 tbsp and a quarter cup 4 tbsp, which is 2 US fl oz. Exact separate fraction arithmetic gives two thirds of a cup as 10 tbsp + 2 tsp and one third as 5 tbsp + 1 tsp. This scalar field accepts neither slash fractions nor compound spoon inputs; a finite rounded decimal of one third is a different quantity. Six tbsp is exactly 0.375 US cups and 3 US fl oz.

Is a fluid ounce the same as an ounce on the scale?

US fluid ounce is a volume of exactly 29.5735295625 mL; an avoirdupois ounce is a mass of exactly 28.349523125 g. Volume and Mass stay separate here. Bridging them requires an applicable supplied density and conditions: mass = volume × density in matching units. There is no water-density shortcut in this converter. Grams to Cups uses named ingredient density conventions; its US cup is rounded to 236.588 mL, while Unit Converter uses exactly 236.5882365 mL. It does not accept an arbitrary user-entered density.

Is dividing by 2 exact, or is the answer rounded?

The US tablespoon-to-US-fluid-ounce ratio is exactly 1/2: a US gallon is exactly 231 in³, a fluid ounce is 1/128 of it and a tablespoon 1/256. Inputs of 0.25, 0.5, 0.75 and 1.5 tbsp give exactly 0.125, 0.25, 0.375 and 0.75 fl oz. Long terminating results can still round at twelve significant digits, so exact definitions do not guarantee an unrounded headline. The mL readout for 1 tbsp is 14.7867647813, rounded from exactly 14.78676478125.

How do I enter half a tablespoon or one and a half?

Use a finite decimal scalar: 0.5 tbsp is 0.25 fl oz, 0.25 tbsp is 0.125 fl oz, 0.75 tbsp is 0.375 fl oz and 1.5 tbsp is 0.75 fl oz. The field accepts signs, correctly grouped thousands, scientific notation and matching unit suffixes. It refuses slash fractions such as 1/2 and compound values. Fraction Calculator supports separate rational arithmetic; entering its rounded decimal here uses that finite decimal rather than the exact fraction.

Why does the page open on tablespoons, and does anything leave my browser?

This focused page opens on Tablespoon (US) to Fluid ounce (US), while preserving the main converter’s saved unit pair. When storage is usable, a saved value and uncommon-unit preference can travel between pages. Its suffix must still match From. Valid deliberate scalar edits can save those fields after a short delay; invalid or incomplete drafts preserve the saved record. Unusable or conflicting records remain until you use Forget saved settings, which keeps the current conversion on screen. Your input and converted values are calculated in the browser and are not uploaded by the converter. The definitions arrive with the page, so conversion needs no external data lookup and keeps working offline after the page has loaded. The core conversion needs no account. Copy result copies the displayed headline without digit-grouping commas; each visible conversion row has its own Copy button. Displayed and copied values round to twelve significant digits. If native copying fails, a complete selectable summary identifies the input, selected pair and conventions and includes every unit in the category, including uncommon units.

Tablespoons to Fluid Ounces (tbsp to fl oz)

A US fluid ounce is exactly 2 US tablespoons, so this conversion is one halving: fluid ounces = tablespoons ÷ 2. Both units are definitions rather than measurements, because a US gallon is exactly 231 cubic inches and an inch is exactly 2.54 cm, which puts the tablespoon at exactly 14.78676478125 mL and the fluid ounce at exactly 29.5735295625 mL. That makes 1 tbsp exactly 0.5 fl oz, 3 tbsp 1.5 fl oz, 4 tbsp 2 fl oz and 16 tbsp 8 fl oz, which is one US cup. This page opens the converter on the Volume category with Tablespoon (US) in the From box and Fluid ounce (US) in the To box, whatever pair you converted last, and it answers while you type. Halving a finite decimal gives another terminating decimal, although long results can still round to twelve significant digits. One US tablespoon is exactly 0.5 US fl oz; one US teaspoon displays as 0.166666666667 US fl oz. Under the answer the same spoonful is listed in the volume units the converter treats as common: millilitres, litres, cubic metres, teaspoons, fluid ounces, cups, pints, quarts and gallons, with those last six in their US sizes. Those figures print to twelve significant digits, so the millilitre row reads 14.7867647813 for one tablespoon, rounded from the exact 14.78676478125. The actual menus use Milliliter (mL) and Liter (L). The tablespoon here is the US customary one and it is the only tablespoon in the menu, so the 15 mL metric spoon and the 20 mL Australian one are worked out in the questions below, along with the imperial fluid ounce.

Tablespoons in fluid ounces, teaspoons, millilitres and cups

Every figure is this converter's own output for that many US tablespoons. The fluid ounce, teaspoon and cup columns are exact, because halving, tripling and dividing by 16 all terminate. Millilitres are the one rounded column, shown to two decimal places: one tablespoon is exactly 14.78676478125 mL.

Common questions

How many fluid ounces is 1 tablespoon?: Half of one exactly: 0.5 fl oz, and the converter prints a clean 0.5 rather than a run of decimals. The amounts asked for next most often: half a tablespoon is 0.25 fl oz, 1.5 tbsp is 0.75 fl oz, 2 tbsp is exactly 1 fl oz, 3 tbsp is 1.5 fl oz, 4 tbsp is 2 fl oz, 6 tbsp is 3 fl oz, 8 tbsp is 4 fl oz, 12 tbsp is 6 fl oz and 16 tbsp is 8 fl oz. Type any of them into the From box and the headline changes without pressing anything.
How many tablespoons are in a fluid ounce?: Two exactly, in US measure. Half a fluid ounce is 1 tbsp, 2 fl oz is 4 tbsp, 4 fl oz is 8 tbsp, and 8 fl oz, which is one US cup, is 16 tbsp. The Swap units button between the two boxes turns this page into a fluid ounces to tablespoons converter without reloading it, and the list under the answer then reads the other way too, with the tablespoon row among the units it prints.
Is this the US tablespoon, the metric one or the Australian one?: Tablespoon (US) here is exactly 14.78676478125 mL, half a US fluid ounce and three US teaspoons. It is the only tablespoon entry. A separately supplied 15 mL tablespoon convention is about 1.4% larger; a supplied 20 mL convention is one third larger than 15 mL. Confirm the source convention instead of inferring it from a country, recipe or spoon. Select Milliliter in From for those supplied volumes: 15 mL displays as 0.507210340528 US fl oz and 20 mL as 0.676280454037 US fl oz.
Does an imperial fluid ounce change the answer?: Yes, by about 4 percent. A US fluid ounce is 29.5735295625 mL against 28.4130625 mL for the imperial one, so measured against the imperial ounce a US tablespoon is 0.520421365393 fl oz rather than a clean 0.5, and 1 imperial fluid ounce is 1.92151988081 US tablespoons rather than 2. Both unit menus carry Fluid ounce (imperial) at all times, so you can select it in the To box; the converter counts it as uncommon, so it only joins the list under the answer once the switch marked Show 5 more is ticked.
How many tablespoons make a cup, and what is a quarter cup?: One exact US cup is 16 US tablespoons or 8 US fluid ounces. Three quarters of a cup is 12 tbsp, half a cup 8 tbsp and a quarter cup 4 tbsp, which is 2 US fl oz. Exact separate fraction arithmetic gives two thirds of a cup as 10 tbsp + 2 tsp and one third as 5 tbsp + 1 tsp. This scalar field accepts neither slash fractions nor compound spoon inputs; a finite rounded decimal of one third is a different quantity. Six tbsp is exactly 0.375 US cups and 3 US fl oz.
Is a fluid ounce the same as an ounce on the scale?: US fluid ounce is a volume of exactly 29.5735295625 mL; an avoirdupois ounce is a mass of exactly 28.349523125 g. Volume and Mass stay separate here. Bridging them requires an applicable supplied density and conditions: mass = volume × density in matching units. There is no water-density shortcut in this converter. Grams to Cups uses named ingredient density conventions; its US cup is rounded to 236.588 mL, while Unit Converter uses exactly 236.5882365 mL. It does not accept an arbitrary user-entered density.
Is dividing by 2 exact, or is the answer rounded?: The US tablespoon-to-US-fluid-ounce ratio is exactly 1/2: a US gallon is exactly 231 in³, a fluid ounce is 1/128 of it and a tablespoon 1/256. Inputs of 0.25, 0.5, 0.75 and 1.5 tbsp give exactly 0.125, 0.25, 0.375 and 0.75 fl oz. Long terminating results can still round at twelve significant digits, so exact definitions do not guarantee an unrounded headline. The mL readout for 1 tbsp is 14.7867647813, rounded from exactly 14.78676478125.
How do I enter half a tablespoon or one and a half?: Use a finite decimal scalar: 0.5 tbsp is 0.25 fl oz, 0.25 tbsp is 0.125 fl oz, 0.75 tbsp is 0.375 fl oz and 1.5 tbsp is 0.75 fl oz. The field accepts signs, correctly grouped thousands, scientific notation and matching unit suffixes. It refuses slash fractions such as 1/2 and compound values.
