Tablespoons to Millilitres (tbsp to mL)

Common questions

How many mL is 1 tablespoon?

One US tablespoon is exactly 14.78676478125 mL and displays as 14.7867647813 mL. A supplied 15 mL spoon convention is a different volume, absent from the menu. Other US examples: 0.5 tbsp displays as 7.39338239063 mL, 1.5 as 22.1801471719 mL, 2 as exactly 29.5735295625 mL, 3 as 44.3602943438 mL, 4 as exactly 59.147059125 mL, 6 as exactly 88.7205886875 mL, 8 as exactly 118.29411825 mL and 16 as exactly 236.5882365 mL. Those exact cases fit the twelve-significant-digit display.

Is a tablespoon 15 mL or 14.79 mL?

Tablespoon (US) here is exactly 14.78676478125 mL. A separately supplied 15 mL convention is about 1.44% larger; 14.79 mL is the US definition rounded to two decimal places. The difference is about 0.21 mL per spoon, 3.41 mL for sixteen spoons and 21.3 mL for one hundred. At two decimal places, sixteen US tbsp is 236.59 mL against 240 mL, and one hundred is 1,478.68 mL against 1,500 mL. These are arithmetic comparisons; the converter does not measure a spoon, infer a recipe convention or judge measurement error.

How do I convert mL back to tablespoons?

Divide by 14.78676478125, or press the Swap units button between the two boxes, which turns this page into a millilitres to tablespoons converter without reloading it. It then reads 5 mL as 0.338140227018 tbsp, 10 mL as 0.676280454037 tbsp, 15 mL as 1.01442068106 tbsp, 20 mL as 1.35256090807 tbsp, 30 mL as 2.02884136211 tbsp, 50 mL as 3.38140227018 tbsp, 100 mL as 6.76280454037 tbsp and 250 mL as 16.9070113509 tbsp. That 1.0144 is the same 1.44 percent from the other direction: a 15 mL spoon is just over one US tablespoon.

What about the Australian tablespoon?

If the source explicitly supplies a 20 mL tablespoon convention, convert that volume by selecting Milliliter. One supplied 20 mL amount displays as 1.35256090807 US tbsp; four are 80 mL, displaying as 5.41024363229 US tbsp. One US tbsp divided by 20 mL is about 0.7393 of that supplied spoon. The 20 mL convention is four supplied 5 mL teaspoons and one third larger than a supplied 15 mL spoon. Teaspoon (US) here is exactly 4.92892159375 mL. A country or recipe alone does not establish any of those conventions.

What is the formula, and is the factor exact?

Use mL = US tbsp × 14.78676478125, and US tbsp = mL / 14.78676478125 in reverse. The factor is exact: 231 international in³ per US liquid gallon, with 2.54 cm per inch, 128 fluid ounces per gallon and 2 tablespoons per fluid ounce. Decimal-rational arithmetic preserves those definitions before twelve-significant-digit display rounding. One tbsp displays as 14.7867647813 mL, and three as 44.3602943438 mL from exactly 44.36029434375. Two tbsp is exactly 29.5735295625 mL and sixteen exactly 236.5882365 mL, both fitting the display.

How do I enter half a tablespoon, or a third of one?

Use a finite decimal scalar; slash fractions such as 1/2 and compound inputs are refused. The field accepts signs, correctly grouped thousands, scientific notation and matching suffixes. For US tablespoons: 0.5 displays as 7.39338239063 mL, 0.25 as 3.69669119531 mL, 0.75 as 11.0900735859 mL and 1,000 as 14,786.7647813 mL. One exact third is one US teaspoon, exactly 4.92892159375 mL. The finite input 0.333333333333 has a slightly smaller exact product yet happens to display the same 4.92892159375 mL. Fraction Calculator supports the separate exact fraction; re-entering its decimal here uses that finite decimal.

Is a tablespoon of flour also 14.79 mL?

A supplied volume of one US tablespoon is exactly 14.78676478125 mL, displaying as 14.7867647813 mL, independently of what occupies that volume. A named ingredient or physical spoon alone does not establish its convention or fill quantity. Unit Converter keeps volume and mass separate. A supplied volume does not establish the mass of an ingredient or an actual filled scoop. Mass = volume × an applicable supplied density in matching units, with the material and conditions specified. Grams to Cups uses named ingredient density conventions rather than arbitrary user-entered density; its US cup is rounded to 236.588 mL, while Unit Converter uses exactly 236.5882365 mL.

Does the page keep this pair, and does anything leave my browser?

This focused page opens on Tablespoon (US) to Milliliter (mL), 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. Show 5 more adds the imperial fluid ounce, pint and gallon plus cubic inch and cubic foot to the readout; both menus always include them. 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.
