8g Baking Powder to Cups
8 grams of baking powder is a small amount, best measured with a spoon rather than a full cup. At 192g per cup, it works out to 0.7 tablespoons.

8 grams of baking powder = 0.04 cups (⅛ cup / 0.7 tbsp / 2.0 tsp)
Baking Powder has a density of approximately 192g per cup. Usually measured in teaspoons rather than cups in recipes. 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 |
|---|---|---|---|---|
| 6g | 0.03 | ⅛ | 0.5 | 1.5 |
| 7g | 0.04 | ⅛ | 0.6 | 1.8 |
| 8g | 0.04 | ⅛ | 0.7 | 2.0 |
| 9g | 0.05 | ⅛ | 0.8 | 2.3 |
| 10g | 0.05 | ⅛ | 0.8 | 2.5 |
The Math for 8g of Baking Powder
8g divided by 192g (the weight of one cup of baking powder) equals 0.04 cups. Multiplying that by 16 gives 0.7 tablespoons, and by 48 gives 2.0 teaspoons, since one cup always equals 16 tablespoons or 48 teaspoons regardless of the ingredient.
Baking Powder is lighter than water, which weighs about 236g per cup. That's why 8g of baking powder takes up more volume (10ml) than the same weight of water would (8ml). For a side-by-side look at how other ingredients compare, see the 8 grams to cups page.
Metric and Imperial Cup Sizes
The 0.04 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 8g, that's ⅛ metric cups or ⅛ imperial cups of baking powder, close to the US figure but not identical. The cup standard switch in the converter above recalculates this instantly for any gram amount.
Making More or Less Than 8g
Doubling a recipe that calls for 8g of baking powder means weighing 16g, or measuring 0.08 cups if you're working by volume instead of weight. Halving it means 4g, or 0.02 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.
How Baking Powder Compares to Similar Ingredients
Within dry goods, density still varies by ingredient. At 8g, active dry yeast (192g per cup) measures ⅛ cup, while chocolate chips (170g per cup) measures ⅛ cup, compared to ⅛ cup for baking powder. Swapping ingredients in a recipe by cup measurement alone, without adjusting for this difference, changes the actual weight used.
Typical Uses for Baking Powder
- Cakes typically use 8g to 12g (about 2 teaspoons) of baking powder.
- Biscuits often call for 10g to 15g per batch.
- Muffin recipes usually need about 8g.
Getting an Accurate Spoon Measurement
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 8 grams of baking powder in cups?+
8 grams of baking powder is 0.04 cups, or 0.7 tablespoons.
Should I use a spoon or a cup for 8g of baking powder?+
At 8g, a tablespoon or teaspoon measurement is usually more practical than a fractional cup. Use 0.7 tablespoons or 2.0 teaspoons.
Is 8 grams of baking powder the same as 8 milliliters?+
Only if it weighed the same as water. 8g of water is about 8ml, while 8g of baking powder is 10ml, because the two have different densities.
Does the answer change for a metric or imperial cup?+
Slightly. 8g of baking powder is ⅛ metric cups or ⅛ imperial cups, close to the US figure but not identical, since each standard defines the cup at a different volume.
