150 grams of baking soda = 0.65 cups (⅔ cup / 10.4 tbsp / 31.3 tsp)
Baking Soda has a density of approximately 230g 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 |
|---|---|---|---|---|
| 130g | 0.57 | ⅝ | 9.0 | 27.1 |
| 140g | 0.61 | ⅝ | 9.7 | 29.2 |
| 150g | 0.65 | ⅔ | 10.4 | 31.3 |
| 160g | 0.70 | ⅔ | 11.1 | 33.4 |
| 170g | 0.74 | ¾ | 11.8 | 35.5 |
How the 150g Figure Is Calculated
150g divided by 230g (the weight of one cup of baking soda) equals 0.65 cups. Multiplying that by 16 gives 10.4 tablespoons, and by 48 gives 31.3 teaspoons, since one cup always equals 16 tablespoons or 48 teaspoons regardless of the ingredient.
Baking Soda is lighter than water, which weighs about 236g per cup. That's why 150g of baking soda takes up more volume (154ml) than the same weight of water would (150ml). For a side-by-side look at how other ingredients compare, see the 150 grams to cups page.
If Your Recipe Uses Metric or Imperial Cups
The 0.65 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 150g, that's ⅝ metric cups or ½ imperial cups of baking soda, close to the US figure but not identical. The cup standard switch in the converter above recalculates this instantly for any gram amount.
Scaling 150g Up or Down
Doubling a recipe that calls for 150g of baking soda means weighing 300g, or measuring 1.30 cups if you're working by volume instead of weight. Halving it means 75g, or 0.33 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.
Baking Soda vs. Other Dry Goods
Within dry goods, density still varies by ingredient. At 150g, baking powder (192g per cup) measures ¾ cup, while active dry yeast (192g per cup) measures ¾ cup, compared to ⅔ cup for baking soda. Swapping ingredients in a recipe by cup measurement alone, without adjusting for this difference, changes the actual weight used.
Where 150g of Baking Soda Fits in a Recipe
- Most cookie recipes use just 4g to 6g (about 1 teaspoon) of baking soda.
- Quick breads typically call for 5g to 8g per loaf.
- Pancake batter usually needs 4g to 5g for a full 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 150 grams of baking soda in cups?+
150 grams of baking soda is 0.65 cups (⅔ cup), or 10.4 tablespoons.
How do I measure 150 grams of baking soda without a scale?+
Use ⅔ cup, spooned in and leveled off with a straight edge. If you only have tablespoons, use 10.4 tablespoons instead.
Why is baking soda's gram-to-cup ratio different from other ingredients?+
Baking Soda weighs 230g per cup because of its own density. Usually measured in teaspoons rather than cups in recipes.
Does a metric or imperial cup change this 150g conversion?+
Yes, slightly. 150g of baking soda is ⅝ metric cups or ½ imperial cups, versus ⅔ US cups, since each cup standard holds a different volume.
