Ingredient measurements
Bread Flour: cups to grams
The stored estimate for bread flour is the same as for all-purpose flour. That is a measuring convention, not a promise that the two flours behave alike in dough. Packing the cup changes the amount of flour relative to the water.

Measuring tip
For several cups of bread flour, weigh the total in one bowl if you can. If using cups, loosen, spoon and level each one consistently; do not compact flour to make the last cup fit.
Measuring several cups for bread dough
For a dough that lists three cups of bread flour, this is the starting weight estimate. Weigh it before adding water so repeated scoops do not change the flour-to-water balance.
- Amount in the recipe (US cups)
- 3 cups
- Estimated scale weight
- About 360 g
Choose the cup size in the recipe
The same ingredient fills a larger cup with more weight. These comparisons keep the stored density fixed and change only the cup capacity. Use a marked measuring cup, not a drinking mug.
- US customary: the basis of both ingredient tables above. The tablespoon column uses 16 US tablespoons per cup.
- UK recipes: follow the author’s stated cup capacity or use the supplied grams or millilitres. A UK recipe does not automatically mean a 250 mL cup.
- Fluid ounces: US and UK markings describe different volumes. They are separate choices in the volume converter below, and neither is an ounce by weight.
Convert cooking volumes
Use this calculator to change between cups, millilitres, decilitres and spoons. Select the measurement system printed in the recipe. It converts volume only; use the ingredient tables above for estimated grams.
1 cup (US) in every unit
A US cup is about 236.6 ml; a metric cup is 250 ml. Choose the measurement system used by your recipe rather than assuming all cups and spoons hold the same amount.
Questions
How many grams is 1 cup of bread flour?
This chart estimates about 120 grams per US customary cup of bread flour. It is a stored kitchen estimate, not an exact weight for every brand or measuring method. Use the recipe’s gram amount if one is given.
How many cups is 100 g of bread flour?
Using this estimate, 100 g is about 0.83 US cups. The table also expresses that same total volume as approximately 13.3 US tablespoons; those spoonfuls are not extra to add to the cups.
Why does my recipe give a different weight per cup?
Cup size, preparation and the way the ingredient fills the measure can differ. A loose powder has air between its particles; packing it makes more fit. Liquids also have different densities. A recipe’s own weight is the better choice for reproducing that recipe.
Which cup should I use for a US or UK recipe?
These charts use the US customary cup, about 236.59 mL. Use the author’s stated capacity for a UK recipe rather than choosing by country alone. If it specifies a 250 mL metric cup, the same density estimate gives about 127 g of bread flour per cup. The 240 mL US legal cup is another distinct setting.
How to use the estimate and check a reference
The tables scale ToolsNow’s stored estimate of 120 g per US customary cup of bread flour. To convert another cup amount, multiply it by that weight. To work backwards from grams, divide by the same weight. Round at the end rather than adding together already-rounded table rows.
For comparison, King Arthur Baking’s ingredient weight chart gives weights with preparation notes, including packed brown sugar and unsifted confectioners’ sugar. These pages retain ToolsNow’s own estimates; they are not a reproduction of that chart. When your recipe or product gives a different weight, prefer that more specific reference.
