You’re standing over a bowl of expensive vanilla bean paste or maybe a potent bottle of cough syrup. The recipe or the label asks for two tablespoons. You reach for that decorative ceramic spoon you bought at a craft fair, or maybe a soup spoon from the silverware drawer. Stop.
If you’ve ever wondered how many ml is two tablespoons, the quick, "Google-snippet" answer is 30 ml.
But here’s the thing: that answer is only "mostly" right. Depending on where your recipe was written, where your measuring spoons were manufactured, or even whether you’re measuring a liquid versus a powder, that 30 ml figure can fluctuate enough to ruin a delicate souffle or, more importantly, mess up a medication dosage. Most people think a tablespoon is a universal constant. It isn’t.
The Math Behind How Many ML is Two Tablespoons
In the United States, we technically play by two different sets of rules. There is the "Legal" cup and spoon used for nutrition labeling, and the "Customary" system used for actual cooking.
Under the US Customary system, one tablespoon is approximately 14.8 ml. Double that, and you get 29.6 ml. However, the FDA mandates that for food labeling purposes, a tablespoon is rounded to exactly 15 ml. So, when you ask how many ml is two tablespoons, the standard industry answer is 30 ml.
But wait. If you are using a recipe from the United Kingdom, Australia, or New Zealand, you’ve entered a different world. In the UK, a tablespoon is traditionally 15 ml, matching the US labeling standard. But in Australia? A tablespoon is a whopping 20 ml. If you’re following an Aussie recipe and you use two US tablespoons, you’re missing 10 ml of volume. That is a massive discrepancy when you're working with stabilizers like gelatin or leavening agents.
Why Your Silverware Isn't a Measuring Tool
Let's be real. We've all done it. We grab a big spoon from the drawer because we’re too lazy to find the ring of plastic measuring spoons buried in the "junk" drawer.
The term "tablespoon" originally referred to a literal spoon used at a table. But modern cutlery is designed for aesthetics and mouthfeel, not volume. A standard dinner spoon can hold anywhere from 7 ml to 13 ml. Rarely does it hit that 15 ml mark perfectly.
I once tried to bake a simple pound cake using a "heaping" dinner spoon of baking powder instead of a measured tablespoon. The cake rose like a monster, hit the top of the oven, and سپس collapsed into a bitter, metallic-tasting puddle. Science doesn't care about your intuition. It cares about volume.

The Metric Conversion Reality
If you're working with a scale—which honestly, you should be—the conversion gets even more specific because of density. But for water-based liquids:
- 1 Tablespoon = 15 ml
- 2 Tablespoons = 30 ml
- 3 Tablespoons = 45 ml
- 4 Tablespoons = 60 ml (which is also exactly 1/4 cup)
Medicine vs. Muffins: When Accuracy is Life or Death
While a few extra milliliters of milk won't kill your pancake batter, the stakes change when you're in the medicine cabinet.
A study published in the International Journal of Clinical Practice highlighted that using household spoons for medication leads to dosing errors ranging from 8% underdose to 141% overdose. That’s terrifying.
If a doctor tells you to take two tablespoons of a supplement or a liquid medication, they are assuming the 30 ml standard. But because human hands are shaky and household spoons are inconsistent, medical professionals are increasingly pushing everyone to use syringes or graduated dosing cups marked in milliliters.
The Dry Ingredient Trap
When we talk about how many ml is two tablespoons, we are talking about volume. But volume is a fickle friend when it comes to solids.
Take flour. If you scoop two tablespoons of flour directly from the bag, you’re packing it down. You might end up with 35 ml worth of mass in a 30 ml space. If you sift it first, you might only get 25 ml.
This is why professional bakers loathe volume measurements. They want grams. 15 ml of water weighs exactly 15 grams. 15 ml of honey? That's about 21 grams. 15 ml of flour? Somewhere around 8 to 9 grams.
If you want to be a better cook, stop thinking about "how many ml" and start thinking about "how many grams." But, if you must stay in the world of volume, always level off your spoons with a flat edge. No "heaping" allowed unless the recipe specifically calls for it.
How to Calibrate Your Kitchen
Think your measuring spoons are accurate? Test them. It’s a fun five-minute science experiment.
- Place a small bowl on a digital kitchen scale.
- Tare the scale to zero.
- Fill your "15 ml" tablespoon with room-temperature water.
- Pour it into the bowl.
The scale should read 15 grams. If it says 12 grams or 18 grams, your "tablespoon" is a liar. Throw it away. Seriously. Cheap plastic spoons from dollar stores are notoriously inaccurate, often warping during high-heat dishwasher cycles.
Cultural Nuances You Didn't Ask For (But Need)
The "Dessertspoon" is the ghost of the kitchen. You'll see it in older British recipes. It sits right between a teaspoon and a tablespoon, usually measuring 10 ml.
Then there's the "Caffè" spoon in Italy or the "Spoonful" in various Mediterranean cultures which can mean anything from 5ml to "whatever your grandmother thinks is right."
In the United States, we are firmly entrenched in the 15 ml per tablespoon camp. If you buy a bottle of Gatorade and look at the serving size, or a bottle of cough syrup, that 15 ml (one tablespoon) or 30 ml (two tablespoons) is the benchmark.
Practical Steps for Perfect Portions
Forget the guesswork. If you want to master the 30 ml pour, follow these rules:
Buy a Graduated Beaker
Small "mini" measuring glasses that look like shot glasses but have ml, tsp, tbsp, and oz markings are superior to spoons. They allow you to see the meniscus—that little curve the liquid makes—at eye level.
Watch the Viscosity
When measuring thick liquids like molasses or honey for your 30 ml requirement, coat the spoon with a tiny bit of neutral oil or cooking spray first. The liquid will slide right out, ensuring you actually get the full 30 ml into the bowl instead of leaving 5 ml stuck to the plastic.
The "Dip and Sweep" Method
For dry ingredients, never use the spoon to pack the ingredient. Dip it in, let it overflow, and sweep the excess off with the back of a butter knife. This is the only way to ensure your two tablespoons of cocoa powder don't turn your cake into a chalky mess.

Check the Origin
If you're using a recipe from a blog, check the "About" page. Is the author in Perth? If so, their "two tablespoons" is 40 ml. Is the author in London? It's 30 ml. Is the author in New York? It's 29.6 ml (but they'll call it 30).
The reality is that 30 ml is the gold standard for two tablespoons in 90% of the world. Just keep a syringe handy for your meds and a scale handy for your bread, and you'll never have to worry about these tiny increments again.
Actionable Next Steps
- Verify your equipment: Perform the "water on a scale" test mentioned above to see if your current tablespoon set is actually 15 ml.
- Switch to a "Mini-Measure" glass: Pick up a graduated glass measure for liquids; it's significantly more accurate than using nested spoons where surface tension can cause over-pouring.
- Check your medication: If you are currently using a kitchen spoon for prescriptions, call your pharmacist and ask for a free oral syringe to ensure you're getting exactly the 15 or 30 ml prescribed.
- Adjust for International Recipes: If cooking from an Australian source, add an extra teaspoon for every tablespoon called for to compensate for their 20 ml standard.
