Quick Answer: 2/3 Cup Butter = How Many Tablespoons?
2/3 cup of butter = 10 tablespoons + 2 teaspoons
This is also sometimes written as 10⅔ tablespoons.
The Maths
- 1 cup = 16 tablespoons
- 2/3 of 16 = 10.667 tablespoons
- 0.667 tablespoons × 3 teaspoons per tablespoon = 2 teaspoons
- Therefore: 2/3 cup = 10 tablespoons + 2 teaspoons

2/3 Cup Butter in Grams
2/3 cup of butter = approximately 151 grams
This assumes standard butter density of 227g per cup (US standard).
If you have a kitchen scale, weighing is the most accurate method — especially if butter has been sitting out at room temperature and may have softened/expanded slightly.
How to Measure 2/3 Cup of Butter Without a Measuring Cup
Method 1: Tablespoons
Measure 10 tablespoons + 2 teaspoons. This is the most accessible method in any kitchen.
Method 2: Water Displacement
- Fill a 1-cup measuring cup with 1/3 cup of cold water.
- Add butter pieces until the water level reaches 1 cup.
- The amount of butter you added = 2/3 cup.
- Drain the water and use the butter.
This method works because water + butter will displace to the exact cup level. It’s particularly useful for softened or melted butter that won’t pack neatly into a dry measuring cup.
Method 3: Weight (Most Accurate)
Place your bowl on a kitchen scale, tare to zero, and add butter until the scale reads 151 grams.
Method 4: From a Butter Block
In India, butter (Amul, Britannia) is sold in 100g, 200g, or 500g blocks. For 2/3 cup (151g):
- From a 200g block: use about ¾ of the block
- From a 500g block: cut off roughly 30% of the block
- Most accurate: weigh it
Indian Butter Measurement Conversions
| Amount | Grams | Amul Butter Equivalent |
|---|---|---|
| 1 tbsp | 14 g | About 1/7 of a 100g pack |
| 1/4 cup (4 tbsp) | 57 g | Just over half a 100g pack |
| 1/3 cup | 76 g | ¾ of a 100g pack |
| 2/3 cup | 151 g | 1½ × 100g packs |
| 1 cup | 227 g | Just over 2 × 100g packs |
Salted vs Unsalted Butter
The conversion (2/3 cup = 151g = 10 tbsp + 2 tsp) is the same regardless of whether butter is salted or unsalted — the volume and weight are identical.
However, if a recipe calls for unsalted butter and you only have salted: reduce any added salt in the recipe by about 1/4 teaspoon per 1/2 cup of butter used. For 2/3 cup, reduce added salt by about 1/3 teaspoon.
Substituting Butter
If you need to substitute for 2/3 cup (151g) of butter:
| Substitute | Amount for 2/3 cup butter | Best For |
|---|---|---|
| Ghee | 2/3 cup (same amount) | Most baking; adds a nutty flavour |
| Coconut oil (solid) | 2/3 cup | Vegan baking; slight coconut flavour |
| Vegetable oil | ½ cup (reduce by ¼) | Moist cakes; not for cookies/pastry |
| Margarine | 2/3 cup (same amount) | Most baking |
