You're standing over a bowl of half-mixed cookie dough. The recipe calls for tablespoons, but you can only find that one sticky teaspoon buried in the drawer. It's frustrating. You need to know exactly how 4 tsps equals how many tablespoons before the baking soda starts reacting or your sauce breaks.
Let's cut to it. 4 teaspoons equals 1 and 1/3 tablespoons.
Most people assume kitchen measurements are always clean, even numbers. They aren't. While three teaspoons make a perfect tablespoon, that fourth one throws a wrench in the works. It creates a fraction that makes people second-guess their entire culinary existence. You aren't alone in this. Honestly, even professional chefs occasionally have to pause and do the mental gymnastics when scaling a recipe up or down by 25 percent.
The Basic Math of the Tablespoon
To understand why four teaspoons equals 1.33 tablespoons, you have to look at the standard US Customary System. In the United States, the ratio is a hard 3:1.
Three teaspoons (tsp) make up one tablespoon (tbsp).
So, if you have four teaspoons, you have one full tablespoon (3 tsp) plus one leftover teaspoon (1 tsp). Since 1 is a third of 3, you get 1 1/3.
It gets weirder if you're looking at decimals. On a digital scale or a calculator, you’ll see 1.333... recurring. In the kitchen, we usually just round that to 1.3. But accuracy matters. If you are baking a delicate souffle or a batch of macarons, that extra third of a teaspoon represents a significant portion of your leavening agent.
Why Getting 4 tsps Right Matters
Imagine you're making a spicy dry rub. If you accidentally put in two tablespoons instead of 1 1/3, you’ve just increased the heat by 50 percent. That's the difference between a pleasant kick and a ruined dinner.
Precision is everything.
In baking, it's even more dire. Baking is chemistry, not just "cooking." If you’re measuring out 4 teaspoons of baking powder and you round up to two tablespoons because it’s "close enough," your cake might rise too fast and then collapse into a sad, dense crater. The ratio of 4 tsps equals how many tablespoons isn't just trivia; it's the structural integrity of your dessert.
The Metric Twist You Didn't Ask For
Here is where things get genuinely annoying. If you are using a recipe from the UK, Australia, or basically anywhere else that uses the metric system, a "tablespoon" might not be what you think it is.

In the US, a tablespoon is roughly 14.8 ml.
In the UK and Canada, it’s usually rounded to 15 ml.
In Australia? A tablespoon is actually 20 ml.
If you are using an Australian recipe and it asks for a tablespoon, they are actually asking for four teaspoons. So, in Melbourne, 4 tsps equals exactly one tablespoon. If you use a US tablespoon (3 tsp) there, your recipe will be short. Always check the origin of your recipe. It's a small detail that saves a lot of heartache.
Quick Conversion Reference
- 1 tsp = 1/3 tbsp
- 2 tsp = 2/3 tbsp
- 3 tsp = 1 tbsp
- 4 tsp = 1 1/3 tbsp
- 5 tsp = 1 2/3 tbsp
- 6 tsp = 2 tbsp
How to Measure 4 Teaspoons Without the Mess
If you don't want to keep track of a tiny 1/3 tablespoon measure (which barely exists anyway), just use the teaspoons. Seriously.
There is no rule that says you have to convert to the largest possible unit. If a recipe calls for 1 1/3 tablespoons, just scoop four level teaspoons. It’s actually more accurate because you aren't trying to eyeball a "third" of a larger spoon.
Make sure you are leveling off your spoons. Use the back of a butter knife. Don't "heap" the spoon unless the recipe explicitly tells you to. A "heaped" teaspoon can actually hold nearly double the volume of a level one, which completely throws off your 4 tsps equals how many tablespoons conversion.
The Liquid vs. Dry Debate
Weight is always better than volume. If you really want to be an expert, get a kitchen scale.
A teaspoon of water weighs about 5 grams. So, 4 teaspoons of water is 20 grams.
However, a teaspoon of flour is much lighter, and a teaspoon of salt is much heavier.
Volume measurements (teaspoons and tablespoons) are notoriously unreliable for dry ingredients because of "packing." If you scoop flour directly from the bag, you’re packing it down. You might end up with 20% more flour than someone who sifts it first. This is why professional bakers almost always talk in grams and kilograms. It removes the guesswork of whether your 4 teaspoons are "packed" or "loose."
Common Kitchen Mistakes
One big mistake is using "silverware" spoons. The spoons you eat cereal with are not measuring spoons. They are decorative. They vary wildly in size. I’ve seen "teaspoons" in silverware sets that actually hold two teaspoons of liquid. If you use those for a recipe, you’re guessing.
Another one? Mixing up the abbreviations.
"tsp" is teaspoon (lowercase).
"Tbsp" or "T" is tablespoon (uppercase).
If you misread 4 tsp as 4 Tbsp, you are putting in three times the amount required. That is a recipe for disaster. Literally.
Practical Steps for Your Kitchen
Stop guessing. If you find yourself constantly searching for 4 tsps equals how many tablespoons, it’s time to change your setup.
First, buy a set of measuring spoons that includes the "odd" sizes. Some sets come with a 1 1/2 tablespoon spoon or a 2-teaspoon spoon. These are lifesavers.
Second, tape a conversion chart to the inside of your pantry door. You think you’ll remember that 4 teaspoons is 1 1/3 tablespoons, but when the onions are burning and the timer is beeping, your brain will betray you.
Third, when in doubt, stay small. It is always easier to count out four small spoons than it is to try and estimate a fraction of a large one.
Grab a permanent marker. Write "3 tsp = 1 Tbsp" on the handle of your tablespoon. It sounds silly, but it’s a visual cue that reinforces the math every time you cook. You’ll eventually stop searching for the answer because the answer will be in your hand.
Clean your spoons, level your measurements, and stop worrying about the fractions. You've got this.
