ML to Tablespoons Converter

How to Use This Tool

One tablespoon equals 14.79 mL. Divide milliliters by 14.79 to get tablespoons. Multiply tablespoons by 14.79 to get milliliters.

1 tbsp to mL works out to 14.79 mL. 2 tbsp to mL comes to 29.57 mL — almost exactly 30 mL. That’s why 30 mL shows up stamped on so many medicine cups and cocktail jiggers.

Formula both directions

• mL to tablespoons: tbsp = mL ÷ 14.79
• Tablespoons to mL: mL = tbsp × 14.79
• Cooking shortcut: most US recipes round to 15 mL per tablespoon. The 0.21 mL gap never shows up in a home kitchen.

Why 14.79 is the number

A US tablespoon equals 1/2 fluid ounce. A US fluid ounce equals 29.5735 mL, so half of that is 14.7868 mL, which rounds to 14.79.

The number comes from the fluid ounce, not from any metric design goal. That’s why cooking charts round it up to a clean 15 mL. The 1.4% gap disappears in normal kitchen measuring error, even though the legal definition still runs through the fluid ounce and the gallon.

Worked examples

Two tablespoons of olive oil for a European recipe: 2 × 14.79 = 29.57 mL, essentially 30 mL. Most European recipes round to exactly this figure.

A 50 mL dose measured with tablespoons: 50 ÷ 14.79 = 3.38 tbsp. That’s an awkward number to eyeball with a spoon — exactly the kind of amount where a marked measuring cup beats guessing.

One tablespoon converted to teaspoons: 14.79 mL ÷ 4.93 mL per tsp = 3 tsp. That’s why “3 teaspoons equal 1 tablespoon” is one of the most memorized kitchen ratios.

The mistake that trips people up

Not every country’s tablespoon is the same size. The US tablespoon holds 14.79 mL. The UK and most metric countries define a tablespoon as 15 mL.

Australia is the outlier. An Australian tablespoon holds 20 mL — noticeably larger, because it’s defined as 4 teaspoons instead of 3.

Follow a US recipe with an Australian tablespoon, or the reverse, and every “tablespoon” measurement is off by roughly 25 to 35%. That matters a lot in baking, where ratios are precise. It matters less in something forgiving like soup.

A second mixup trips people up too: mistaking “tbsp” for “tsp” in handwritten or abbreviated recipes. A tablespoon holds 3 times what a teaspoon holds. Misread the abbreviation, and a measurement gets tripled or cut to a third — a mistake that shows up fast in baking.

Where these searches come from

“1 tbsp to ml” and “2 tbsp to ml” are overwhelmingly recipe-driven searches. Someone is cooking from a US recipe with a metric measuring set. Or they’re adapting an international recipe listed in mL to fit a standard American spoon set.

That’s different from a “how many ml in a tablespoon” guide search, which tends to be a one-off curiosity question. This converter is built for the in-the-middle-of-cooking lookup, with both directions ready at a glance.

Medicine dosing is the second major use case. Liquid medications often list dosage in mL on the label, but get administered with a kitchen tablespoon instead of a proper dosing spoon.

That’s risky. Kitchen tablespoons vary in actual volume more than a marked measuring spoon does. If a dose is listed in mL, treat a tablespoon conversion as a rough guide only. Use an actual marked dosing device for anything more precise than “approximately.”

Two everyday anchors help here. A standard shot glass holds about 44 mL, close to 3 tablespoons. That’s handy for eyeballing a “3 tbsp” measurement without pulling out a spoon.

A tablespoon of butter weighs about 14 g, close in volume to 14.79 mL. That’s why US butter sticks come pre-scored into tablespoon segments — each notch marks roughly one true tablespoon.

Frequently Asked Questions

How many mL is 1 tablespoon?
One tablespoon equals 14.79 mL (14.7868 mL exactly), commonly rounded to 15 mL for cooking.

How many mL is 2 tablespoons?
2 × 14.79 = 29.57 mL, essentially 30 mL.

How many tablespoons is 30 mL?
30 ÷ 14.79 = 2.03 tbsp, close enough to 2 tablespoons for any recipe.

Is a metric tablespoon the same as a US tablespoon?
Not quite. A US tablespoon holds 14.79 mL. A metric or UK tablespoon holds 15 mL. An Australian tablespoon holds 20 mL.

How many teaspoons are in a tablespoon?
Three teaspoons make one tablespoon in the US system: 14.79 mL ÷ 4.93 mL equals 3.

Why do some charts round 1 tbsp to 15 mL instead of 14.79 mL?
Because 15 mL is a clean, easy-to-measure number. The 1.4% gap between 14.79 and 15 mL is invisible in normal cooking.
