80 Grams of Baking Soda in Cups
80 grams of baking soda doesn't land on a clean fraction, so the result below is calculated exactly rather than rounded to a common measure. Based on a density of 230g per cup, it equals 0.35 cups.

- 0.35 (⅓)
- Tablespoons

80 grams of baking soda = 0.35 cups (⅓ cup / 5.6 tbsp / 16.7 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 |
|---|---|---|---|---|
| 70g | 0.30 | ⅓ | 4.9 | 14.6 |
| 75g | 0.33 | ⅓ | 5.2 | 15.7 |
| 80g | 0.35 | ⅓ | 5.6 | 16.7 |
| 85g | 0.37 | ⅜ | 5.9 | 17.7 |
| 90g | 0.39 | ⅜ | 6.3 | 18.8 |
How 80g Converts, Step by Step
80g divided by 230g (the weight of one cup of baking soda) equals 0.35 cups. Multiplying that by 16 gives 5.6 tablespoons, and by 48 gives 16.7 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 80g of baking soda takes up more volume (82ml) than the same weight of water would (80ml). For a side-by-side look at how other ingredients compare, see the 80 grams to cups page.
If You're Using a Metric or Imperial Cup
The 0.35 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 80g, that's ⅓ metric cups or ¼ 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 This 80g Amount
Doubling a recipe that calls for 80g of baking soda means weighing 160g, or measuring 0.70 cups if you're working by volume instead of weight. Halving it means 40g, or 0.17 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 Next to Other Dry Goods
Within dry goods, density still varies by ingredient. At 80g, baking powder (192g per cup) measures ⅜ cup, while active dry yeast (192g per cup) measures ⅜ cup, compared to ⅓ cup for baking soda. Swapping ingredients in a recipe by cup measurement alone, without adjusting for this difference, changes the actual weight used.
Where This Amount Shows Up in Recipes
- 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.
Measuring This Precisely
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 80 grams of baking soda in cups exactly?+
80 grams of baking soda equals 0.35 cups, based on a density of 230g per cup.
Why doesn't 80g of baking soda match a simple fraction?+
80g isn't a multiple of baking soda's per-cup weight, so the cup value lands between common fractions. The closest practical measure is ⅓ cup.
What's the most reliable way to measure 80g of baking soda?+
A kitchen scale set to grams gives an exact 80g reading. Cups only approximate this amount, since ⅓ cup rounds to the nearest practical fraction.
Is 80g likely a typo for a rounder amount?+
Possibly, if a recipe seems to expect a cleaner number. Check the nearby amounts table below for the closest common gram values for baking soda.
