Quick Answer: There are 10 tablespoons plus 2 teaspoons in 2/3 cup. You can also write it as 10 2/3 tablespoons, but that is harder to measure in a real kitchen. The easiest exact method is to measure 10 full tablespoons, then add 2 teaspoons.
If you are in the middle of a recipe and wondering how many tablespoons in 2/3 cup, here is the simple answer:
2/3 cup = 10 tablespoons + 2 teaspoons
That is the cleanest way to measure it if you do not have a 2/3 cup measuring cup.
You can also use a 1/3 cup measure twice, fill a liquid measuring cup to the 2/3 line, or use a kitchen scale if you want the most accurate measurement.
How Many Tablespoons Are in 2/3 Cup?
There are 10 tablespoons plus 2 teaspoons in 2/3 cup.
Here is the math:
- 1 cup = 16 tablespoons
- 2/3 cup = 16 × 2/3
- 2/3 cup = 10.666 tablespoons
- 0.666 tablespoon = 2 teaspoons
- So, 2/3 cup = 10 tablespoons + 2 teaspoons
The most practical kitchen answer is:
2/3 cup = 10 tablespoons + 2 teaspoons
Quick 2/3 Cup Conversion Chart
| Measurement | Equivalent |
|---|---|
| 2/3 cup | 10 tablespoons + 2 teaspoons |
| 2/3 cup | 10 2/3 tablespoons |
| 2/3 cup | 32 teaspoons |
| 2/3 cup | About 158 milliliters |
| 2/3 cup | About 5.3 fluid ounces |
| 2/3 cup | About 0.67 cup |
If a recipe calls for 2/3 cup and you only have a tablespoon, measure 10 tablespoons + 2 teaspoons. That gives you the exact amount without guessing.
Easiest Ways to Measure 2/3 Cup
There are a few simple ways to measure 2/3 cup, depending on what tools you have.
Method 1: Use 10 Tablespoons Plus 2 Teaspoons
This is the best method if you only have measuring spoons. Measure 10 full tablespoons, then add 2 teaspoons. That equals 2/3 cup exactly.
Method 2: Use a 1/3 Cup Twice
This is the easiest method if you have a 1/3 cup measure. Fill it twice. No math needed.
Method 3: Use a Liquid Measuring Cup
Most liquid measuring cups have a 2/3 cup line. Fill to the 2/3 mark and check at eye level. Works best for water, milk, broth, soy sauce, oil, or vinegar.
Method 4: Use a Kitchen Scale
A kitchen scale is the most accurate method, especially for baking and meal prep recipes you repeat weekly. The weight changes by ingredient: 2/3 cup honey weighs 224g, while 2/3 cup rolled oats weighs only 60 to 65g.

How Many Teaspoons Are in 2/3 Cup?
There are 32 teaspoons in 2/3 cup. Here is the math: 1 cup = 48 teaspoons, so 2/3 cup = 48 × 2/3 = 32 teaspoons. Measuring 32 teaspoons works, but it takes time. Use 10 tablespoons plus 2 teaspoons instead when possible.
How Many Milliliters Are in 2/3 Cup?
There are about 158 milliliters in 2/3 cup. For most cooking, rounding to 160 ml is fine. For baking, use the exact recipe measurement.
| Cups | Milliliters |
|---|---|
| 1/4 cup | 59 ml |
| 1/3 cup | 79 ml |
| 1/2 cup | 118 ml |
| 2/3 cup | 158 ml |
| 3/4 cup | 177 ml |
| 1 cup | 237 ml |
How Many Fluid Ounces Are in 2/3 Cup?
There are about 5.3 fluid ounces in 2/3 cup. Here is the math: 1 cup = 8 fluid ounces, so 2/3 cup = 5.33 fluid ounces.
Dry vs Liquid Measurements: Does It Matter?
For basic cooking, sauces, marinades, and most meal prep recipes, a small difference usually will not ruin the dish. For baking, accuracy matters more.
Use a liquid measuring cup for water, milk, broth, soy sauce, vinegar, and oil. Fill to the 2/3 cup line and check at eye level.
Use dry measuring cups for flour, sugar, rice, oats, breadcrumbs, protein powder, and seasoning blends. Scoop the ingredient in, then level it off with the back of a knife.
For sticky ingredients like honey, peanut butter, Greek yogurt, and tahini, a kitchen scale is usually easier and cleaner than a cup.
Common 2/3 Cup Ingredient Conversions by Weight
The volume is the same, but the weight changes by ingredient. Brand, texture, and packing method can all shift the number slightly.
| Ingredient | 2/3 Cup Approx. Weight |
|---|---|
| Water | 158 g |
| Milk | 163 g |
| Olive oil | 144 g |
| Honey | 224 g |
| Greek yogurt | 150 to 160 g |
| Cottage cheese | 145 to 155 g |
| Dry rice | 125 to 130 g |
| Rolled oats | 60 to 65 g |
| All-purpose flour | 80 to 85 g |
| Granulated sugar | 130 to 135 g |
| Brown sugar, packed | 140 to 145 g |
| Peanut butter | 170 to 175 g |
For repeat meal prep recipes, weigh the ingredient once and write it down. Future prep is faster when you work directly with a scale.
High-Protein Meal Prep Ingredients at 2/3 Cup
These numbers come up constantly on Sunday prep days. Most conversion guides skip protein foods entirely. This table covers the ones you will actually reach for when building bowls, sauces, and egg dishes.
| Ingredient | 2/3 Cup Weight | Approx. Protein |
|---|---|---|
| Cooked chicken breast, diced | 85 to 90 g (about 3 oz) | 26 to 28 g |
| Cooked ground turkey, crumbled | 115 to 120 g | 30 to 32 g |

| Canned tuna, drained | 120 to 130 g | 28 to 32 g |
| Canned chickpeas, drained | 100 to 110 g | 8 to 9 g |
| Shelled edamame | 85 to 90 g | 8 g |
| Whey protein powder, unflavored | 55 to 65 g (varies by brand) | 40 to 50 g |
Protein powder varies most by brand. Always weigh it rather than measuring by volume if you are tracking macros closely.
Why 2/3 Cup Comes Up So Often in Meal Prep
The 2/3 cup measurement shows up often because it is a common middle-size portion. You will see it in marinades, stir-fry sauces, salad dressings, rice portions, oatmeal bowls, Greek yogurt bowls, cottage cheese bowls, dry rubs, batch sauces, protein pancake batter, and meal prep bowls.
If you are building your meal prep routine, this high-protein meal prep grocery list can help you shop for the ingredients you will measure most often.
Common Meal Prep Measurements Using 2/3 Cup

Is 2/3 Cup the Same as 10 Tablespoons?
Not exactly. 10 tablespoons is slightly less than 2/3 cup. The exact amount is 10 tablespoons plus 2 teaspoons. If you only use 10 tablespoons, you are short by 2 teaspoons. For sauces and marinades, that usually does not matter. For baking, use the full amount.
Can You Round 2/3 Cup to 11 Tablespoons?
You can, but it will be slightly over.
| Measurement | Result |
|---|---|
| 10 tablespoons | Slightly under 2/3 cup |
| 10 tablespoons + 2 teaspoons | Exact 2/3 cup |
| 11 tablespoons | Slightly over 2/3 cup |
For cooking, 11 tablespoons is usually fine for sauce, broth, or marinade. For baking, use the exact measurement.
Best Way to Measure 2/3 Cup for Baking
- Use a 2/3 cup measure if you have one.
- Use a 1/3 cup measure twice.
- Use 10 tablespoons plus 2 teaspoons.
- Use a kitchen scale if the recipe provides grams.
For flour, do not scoop directly from the bag. Spoon flour into the measuring cup, then level it off. Scooping packs flour and adds too much.
Best Way to Measure 2/3 Cup for Sauces and Marinades
For sauces and marinades, you have more flexibility. Use a liquid measuring cup, 10 tablespoons plus 2 teaspoons, a 1/3 cup twice, or a kitchen scale for sticky ingredients like honey.
If you make the same sauce every week, write down the gram weight after measuring once. Future prep is faster when you can add straight to a bowl on the scale.

3 Measuring Mistakes That Derail Meal Prep Recipes
The #1 mistake is scooping protein powder directly from the tub with a dry measuring cup. Protein powder compresses when scooped. You can end up 10 to 15% over the intended amount without realizing it. Fix: spoon protein powder loosely into the cup first, then level off with a straight edge. Better still, weigh it. 2/3 cup of whey protein powder = roughly 55 to 65g depending on brand.
Mistake 2: Measuring peanut butter or tahini in a cup instead of by weight. Sticky nut butters do not level off cleanly, so the volume is inconsistent. A 2/3 cup of peanut butter can vary by 15 to 20g depending on how you pack it. Fix: use a scale. 2/3 cup peanut butter = about 170 to 175g.
Mistake 3: Using a liquid measuring cup for dry oats or flour. Liquid cup markings are calibrated for water. When you eyeball dry ingredients in a liquid cup, the visual line does not match true volume. You end up with more oats or flour than the recipe calls for. Fix: use a standard dry measuring cup, scoop, then level off.
