450 Grams of Baking Powder in Cups
450 grams of baking powder 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 192g per cup, it equals 2.34 cups.

450 grams of baking powder = 2.34 cups (2⅓ cups / 37.5 tbsp / 112.5 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 |
|---|---|---|---|---|
| 400g | 2.08 | 2⅛ | 33.3 | 100.0 |
| 425g | 2.21 | 2¼ | 35.4 | 106.3 |
| 450g | 2.34 | 2⅓ | 37.5 | 112.5 |
| 475g | 2.47 | 2½ | 39.6 | 118.8 |

How 450g Converts, Step by Step
450g divided by 192g (the weight of one cup of baking powder) equals 2.34 cups. Multiplying that by 16 gives 37.5 tablespoons, and by 48 gives 112.5 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 450g of baking powder takes up more volume (555ml) than the same weight of water would (451ml). For a side-by-side look at how other ingredients compare, see the 450 grams to cups page.
If You're Using a Metric or Imperial Cup
The 2.34 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 450g, that's 2¼ metric cups or 1⅞ 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.
Scaling This 450g Amount
Doubling a recipe that calls for 450g of baking powder means weighing 900g, or measuring 4.69 cups if you're working by volume instead of weight. Halving it means 225g, or 1.17 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 Powder Next to Other Dry Goods
Within dry goods, density still varies by ingredient. At 450g, active dry yeast (192g per cup) measures 2⅓ cups, while chocolate chips (170g per cup) measures 2⅔ cups, compared to 2⅓ cups for baking powder. 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
- 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.
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 450 grams of baking powder in cups exactly?+
450 grams of baking powder equals 2.34 cups, based on a density of 192g per cup.
Why doesn't 450g of baking powder match a simple fraction?+
450g isn't a multiple of baking powder's per-cup weight, so the cup value lands between common fractions. The closest practical measure is 2⅓ cups.
What's the most reliable way to measure 450g of baking powder?+
A kitchen scale set to grams gives an exact 450g reading. Cups only approximate this amount, since 2⅓ cups rounds to the nearest practical fraction.
Is 450g 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 powder.
