How Many Tablespoons In a 1/3 Cup? | No Guesswork Needed

One-third cup equals 5 tablespoons plus 1 teaspoon, or 16 teaspoons total.

That’s the full answer, and it’s the one most home cooks need. If your recipe calls for 1/3 cup and your measuring cup is missing, you can still get there with tablespoons. You just need one clean conversion and a steady hand.

In U.S. kitchen measures, 1 cup equals 16 tablespoons. Split that into thirds and you get 5 tablespoons plus 1 teaspoon. The math works because 1 tablespoon equals 3 teaspoons, so 1/3 cup lands at 16 teaspoons total.

This comes up all the time when you’re baking cookies, mixing a sauce, or halving a recipe on the fly. A wrong scoop can throw off texture, taste, and bake time. A little extra flour can make dough stiff. Too much oil can leave a dressing flat and greasy. So this tiny conversion pulls a lot of weight in the kitchen.

How Many Tablespoons In a 1/3 Cup? The Exact Breakdown

The cleanest way to measure 1/3 cup with spoons is this:

• 5 tablespoons
• Plus 1 teaspoon

If you only remember one line from this article, make it that one. It’s the practical version of the math, and it’s the one printed in many kitchen conversion charts.

The USDA measurement conversion tables list 1/3 cup as 5 tablespoons plus 1 teaspoon. That same chart also shows 1 cup as 16 tablespoons, which is the source of the conversion most cooks already know.

Why The Math Works

Start with the standard U.S. cup. One cup equals 16 tablespoons. Divide 16 by 3 and you get 5 and 1/3 tablespoons. That leftover third of a tablespoon turns into 1 teaspoon, since 1 tablespoon equals 3 teaspoons.

That gives you three matching ways to read the same amount:

• 1/3 cup
• 5 tablespoons + 1 teaspoon
• 16 teaspoons

The NIST kitchen equivalency chart also places 1/3 cup at 80 mL for home cooking. That metric view is handy when you’re using a jug with milliliter marks instead of cups and spoons.

When This Conversion Matters Most

You can get away with a rough pour in soups and stews. Baking is less forgiving. Flour, sugar, butter, milk, oil, cocoa, and nut butters all behave a bit differently when volume drifts. A small miss can change spread, rise, browning, or crumb.

That’s why cooks reach for this conversion so often. Many measuring spoon sets include tablespoons and teaspoons, but not every set includes a 1/3-cup scoop. Even when it does, the spoon route can be faster when you’re already working over a mixing bowl.

It also helps when you’re doubling or cutting a recipe. Once you know what 1/3 cup looks like in spoons, the rest gets less messy. You’re not stuck pausing mid-recipe to search for a chart or second-guess the fill line on a cup.

Tablespoons In One-Third Cup For Cooking And Baking

Volume conversions are easiest when you can see them side by side. This chart gives you the kitchen amounts that pair most often with 1/3 cup and other nearby cup measures.

Cup Measure	Tablespoons	Teaspoons
1/16 cup	1 tablespoon	3 teaspoons
1/8 cup	2 tablespoons	6 teaspoons
1/6 cup	2 tablespoons + 2 teaspoons	8 teaspoons
1/4 cup	4 tablespoons	12 teaspoons
1/3 cup	5 tablespoons + 1 teaspoon	16 teaspoons
3/8 cup	6 tablespoons	18 teaspoons
1/2 cup	8 tablespoons	24 teaspoons
2/3 cup	10 tablespoons + 2 teaspoons	32 teaspoons
3/4 cup	12 tablespoons	36 teaspoons
1 cup	16 tablespoons	48 teaspoons

That table does more than answer one question. It helps you spot the pattern. Quarter cup jumps to 4 tablespoons. Half cup lands at 8. Full cup goes to 16. Once those anchor points are in your head, 1/3 cup stops feeling odd.

Dry Vs. Liquid Ingredients

For volume, the conversion stays the same whether you’re measuring water, oil, sugar, or flour. One-third cup is still 5 tablespoons plus 1 teaspoon. What changes is how the ingredient settles into the spoon or cup.

Flour can pack down if you dig straight into the bag. Brown sugar can mound hard if you press it in. Peanut butter clings to the spoon and leaves a streak behind. So the conversion is fixed, but your measuring method still matters.

The FDA’s household metric equivalency guidance ties a tablespoon to 15 mL and a cup to 240 mL for labeling. That lines up with the kitchen rule used across U.S. recipe charts.

Best Ways To Measure 1/3 Cup Without A 1/3-Cup Measure

If you’re missing the right cup, you’ve got options. Some are more accurate than others, but all can work when done with care.

Use 5 Tablespoons Plus 1 Teaspoon

This is the straight conversion. It’s the best pick when you have standard measuring spoons and want the exact amount.

Use 16 Teaspoons

This works in a pinch. It’s slower, so it makes more sense for one ingredient than for a whole recipe.

Use Two 1/6-Cup Portions If Your Set Has One

Some measuring sets include a 1/6-cup scoop. Two of those equal 1/3 cup. Not every drawer has one, but it’s handy when it shows up.

Use Metric Marks

If you’ve got a measuring jug with milliliters, fill to 80 mL for home cooking. That can be easier with liquids than juggling spoons over a bowl.

Method	Equivalent To 1/3 Cup	Works Best For
Tablespoons + teaspoon	5 tablespoons + 1 teaspoon	Most dry and liquid ingredients
Teaspoons only	16 teaspoons	Small batches and backup measuring
Metric jug	80 mL	Liquids, oils, milk, water
Two 1/6-cup scoops	2 x 1/6 cup	Dry goods when that scoop is available

Common Slips That Throw Off The Measurement

The biggest slip is rounding 1/3 cup to 5 tablespoons and stopping there. That leaves out the extra teaspoon. In some recipes, that gap won’t wreck dinner. In baking, it can nudge the balance more than you’d think.

Another slip is using eating spoons from the drawer instead of measuring spoons. Tableware isn’t standard. One soup spoon may hold more than another, and that can stack up fast.

Leveling matters too. For dry ingredients, sweep the top flat with a knife or straight edge. For sticky ingredients, a light coat of oil on the spoon helps the full amount slide out instead of clinging to the bowl of the spoon.

A Few Handy Kitchen Shortcuts

If you cook often, a few small patterns can save you from reaching for your phone every time:

• 1 cup = 16 tablespoons
• 1/2 cup = 8 tablespoons
• 1/4 cup = 4 tablespoons
• 1 tablespoon = 3 teaspoons
• 1/3 cup = 5 tablespoons + 1 teaspoon

That last line sits neatly between 1/4 cup and 1/2 cup, which makes it easier to remember. It’s not a neat whole-tablespoon number, and that’s why people pause on it. Once you pair it with the extra teaspoon, it sticks.

So the next time a recipe asks for 1/3 cup and your measuring cup is nowhere to be found, you’re still set. Scoop 5 tablespoons, add 1 teaspoon, and move on.
