20g Bread Flour to Cups
20 grams of bread flour is a small amount, best measured with a spoon rather than a full cup. At 127g per cup, it works out to 2.5 tablespoons.

20 grams of bread flour = 0.16 cups (⅛ cup / 2.5 tbsp / 7.6 tsp)
Bread Flour has a density of approximately 127g per cup. Slightly denser than all-purpose due to higher protein content. 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 |
|---|---|---|---|---|
| 10g | 0.08 | ⅛ | 1.3 | 3.8 |
| 15g | 0.12 | ⅛ | 1.9 | 5.7 |
| 20g | 0.16 | ⅛ | 2.5 | 7.6 |
| 25g | 0.20 | ¼ | 3.1 | 9.4 |
| 30g | 0.24 | ¼ | 3.8 | 11.3 |
The Math for 20g of Bread Flour
20g divided by 127g (the weight of one cup of bread flour) equals 0.16 cups. Multiplying that by 16 gives 2.5 tablespoons, and by 48 gives 7.6 teaspoons, since one cup always equals 16 tablespoons or 48 teaspoons regardless of the ingredient.
Bread Flour is lighter than water, which weighs about 236g per cup. That's why 20g of bread flour takes up more volume (37ml) than the same weight of water would (20ml). For a side-by-side look at how other ingredients compare, see the 20 grams to cups page.
Metric and Imperial Cup Sizes
The 0.16 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 20g, that's ⅛ metric cups or ⅛ imperial cups of bread flour, 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 20g
Doubling a recipe that calls for 20g of bread flour means weighing 40g, or measuring 0.31 cups if you're working by volume instead of weight. Halving it means 10g, or 0.08 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 Bread Flour Compares to Similar Ingredients
Within flours, density still varies by ingredient. At 20g, all-purpose flour (125g per cup) measures ⅛ cup, while coconut flour (112g per cup) measures ⅛ cup, compared to ⅛ cup for bread flour. Swapping ingredients in a recipe by cup measurement alone, without adjusting for this difference, changes the actual weight used.
Typical Uses for Bread Flour
- A basic sourdough loaf often uses 500g of bread flour as its base.
- Pizza dough for two pies typically calls for 300g to 400g.
- Bagels usually need about 480g of bread flour per dozen.
Getting an Accurate Spoon Measurement
Flours
Spoon the flour into the cup, then level it off with a straight edge. Never scoop directly from the bag — that packs it down and adds extra weight.
For exact results
Sifting before measuring lowers the weight per cup by adding air, so a recipe written for sifted flour will call for a slightly larger volume than one written for unsifted. Check whether your recipe specifies sifted flour before comparing it to a standard chart.

Frequently Asked Questions
What is 20 grams of bread flour in cups?+
20 grams of bread flour is 0.16 cups, or 2.5 tablespoons.
Should I use a spoon or a cup for 20g of bread flour?+
At 20g, a tablespoon or teaspoon measurement is usually more practical than a fractional cup. Use 2.5 tablespoons or 7.6 teaspoons.
Is 20 grams of bread flour the same as 20 milliliters?+
Only if it weighed the same as water. 20g of water is about 20ml, while 20g of bread flour is 37ml, because the two have different densities.
Does the answer change for a metric or imperial cup?+
Slightly. 20g of bread flour 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.
