100 grams of protein powder = 0.83 cups (⅞ cup / 13.3 tbsp / 40.0 tsp)
Protein Powder has a density of approximately 120g per cup. Whey and plant-based blends vary by brand — check the label. Source: USDA FoodData Central. This is the figure used everywhere on this page, including the tablespoon and teaspoon values, so the numbers stay consistent whether you're reading the summary line, the table, or the FAQ answers below.
| Grams | Cups | Fraction | Tablespoons | Teaspoons |
|---|---|---|---|---|
| 90g | 0.75 | ¾ | 12.0 | 36.0 |
| 95g | 0.79 | ¾ | 12.7 | 38.0 |
| 100g | 0.83 | ⅞ | 13.3 | 40.0 |
| 110g | 0.92 | ⅞ | 14.7 | 44.0 |
| 120g | 1.00 | 1 | 16.0 | 48.0 |
How the 100g Figure Is Calculated
100g divided by 120g (the weight of one cup of protein powder) equals 0.83 cups. Multiplying that by 16 gives 13.3 tablespoons, and by 48 gives 40.0 teaspoons, since one cup always equals 16 tablespoons or 48 teaspoons regardless of the ingredient.
Protein Powder is lighter than water, which weighs about 236g per cup. That's why 100g of protein powder takes up more volume (197ml) than the same weight of water would (100ml). For a side-by-side look at how other ingredients compare, see the 100 grams to cups page.
If Your Recipe Uses Metric or Imperial Cups
The 0.83 cup figure above uses the US Customary cup (236.588ml). Recipes written outside the US sometimes use a metric cup (250ml) or an imperial (uk) cup (284.131ml) instead. At 100g, that's ¾ metric cups or ⅔ imperial cups of protein powder, close to the US figure but not identical. The cup standard switch in the converter above recalculates this instantly for any gram amount.
Scaling 100g Up or Down
Doubling a recipe that calls for 100g of protein powder means weighing 200g, or measuring 1.67 cups if you're working by volume instead of weight. Halving it means 50g, or 0.42 cups. Weight scales exactly with simple multiplication; cup measurements compound any scooping error each time they're doubled or halved, so weighing is more reliable the more a recipe is scaled.
Protein Powder vs. Other Dry Goods
Within dry goods, density still varies by ingredient. At 100g, cornstarch (128g per cup) measures ¾ cup, while rolled oats (90g per cup) measures 1⅛ cup, compared to ⅞ cup for protein powder. Swapping ingredients in a recipe by cup measurement alone, without adjusting for this difference, changes the actual weight used.
Where 100g of Protein Powder Fits in a Recipe
- A single protein shake serving typically uses 30g to 40g of protein powder.
- Protein pancake recipes often call for 30g mixed into the batter.
- No-bake protein bars usually need about 60g to 90g per batch.
How to Measure It Accurately
Dry Goods
Spoon into the cup and level off. Ingredients like cocoa powder benefit from a quick sift first to break up clumps.
For exact results
Baking soda and baking powder should always be measured with a dry measuring spoon, leveled flat — a heaping spoonful of either can meaningfully change how a baked good rises.

Frequently Asked Questions
What is 100 grams of protein powder in cups?+
100 grams of protein powder is 0.83 cups (⅞ cup), or 13.3 tablespoons.
How do I measure 100 grams of protein powder without a scale?+
Use ⅞ cup, spooned in and leveled off with a straight edge. If you only have tablespoons, use 13.3 tablespoons instead.
Why is protein powder's gram-to-cup ratio different from other ingredients?+
Protein Powder weighs 120g per cup because of its own density. Whey and plant-based blends vary by brand — check the label.
Does a metric or imperial cup change this 100g conversion?+
Yes, slightly. 100g of protein powder is ¾ metric cups or ⅔ imperial cups, versus ⅞ US cups, since each cup standard holds a different volume.
