How Many Grams in Half a Cup of Flour?
Half a cup of all-purpose flour is 60 grams — measured the way flour should always be measured: spooned loosely into a dry cup and leveled flat with a straight edge.
That number comes straight from the standard 120 g per cup used by U.S. test kitchens and most baking books written in weights. Half of 120 is 60, and the arithmetic stays that simple as long as you are measuring all-purpose flour. Once you swap in bread flour, cake flour, rye, or almond flour, the scale reading changes — sometimes by 50%.
| Flour type | ½ cup | ⅓ cup | ¼ cup | ⅛ cup |
|---|---|---|---|---|
| All-purpose | 60 g | 40 g | 30 g | 15 g |
| Bread flour | 65 g | 43 g | 33 g | 16 g |
| Cake flour | 57 g | 38 g | 29 g | 14 g |
| Pastry flour | 53 g | 35 g | 27 g | 13 g |
| Whole wheat | 60 g | 40 g | 30 g | 15 g |
| White whole wheat | 60 g | 40 g | 30 g | 15 g |
| ”00” / doppio zero | 63 g | 42 g | 31 g | 16 g |
| Semolina | 84 g | 56 g | 42 g | 21 g |
| Rye | 51 g | 34 g | 26 g | 13 g |
| Spelt | 60 g | 40 g | 30 g | 15 g |
| Almond flour | 48 g | 32 g | 24 g | 12 g |
| Coconut flour | 56 g | 37 g | 28 g | 14 g |

Why Half a Cup Is the Hardest Amount to Get Right
Halving a cup sounds harmless, but a half cup is where volume measuring starts to punish you.
A one-cup measure scooped straight into the flour bag can hold 140–155 g instead of 120 g. Do the same thing with a half-cup measure and the error compounds, because a small cup is easier to overfill and harder to level cleanly. A “half cup” pulled from a scooping session can easily weigh 70–78 g — a 15 to 30% overage.
In a recipe that already uses a small amount of flour, that is not a rounding error. Small-batch recipes have narrow tolerances:
- 6 small cookies or 4 cupcakes. An extra 12 g of flour turns a soft dough into a dry, crumbly one.
- A half-batch of a 12-muffin recipe. The liquid-to-flour ratio shifts, and the muffins stop doming.
- A roux or a pan sauce. Flour is the thickener; 25% more of it means a paste instead of a sauce.
- A single-serve mug cake or a small quickbread. At this scale, 15 g is a meaningful fraction of the whole formula.
The fix is the same at every scale: spoon the flour into the cup until it mounds, then sweep the excess off with the flat back of a knife. Never tap the cup on the counter, never shake it level, and never pack flour the way you pack brown sugar.
The Half-Cup Amounts You Will Actually Use
Most recipes that call for half a cup of flour fall into one of a few patterns. Here is what those amounts look like once converted, which is useful when you are working across two recipes at once:
- ½ cup all-purpose flour = 60 g = 8 level tablespoons = 2 ounces
- ½ cup bread flour = 65 g = 8 level tablespoons
- ½ cup cake flour = 57 g = 8 level tablespoons, sifted if the recipe says so
- ½ cup whole wheat flour = 60 g (interchangeable with all-purpose by weight, not by volume)
- ½ cup almond flour = 48 g, and it will not behave like wheat flour in a batter
The tablespoon line matters because it is your backup measuring path. Sixteen tablespoons make a cup, so eight make a half cup. If your dry measuring cups are dirty or missing the half-cup ring, eight level tablespoons of all-purpose flour gets you to 60 g — accurate to within a gram or two as long as you level each spoon.
A Worked Example: Halving a Small-Batch Cookie Recipe
Say you have a recipe for 12 cookies that calls for 1 cup all-purpose flour, and you want a half batch. It is tempting to measure “½ cup + a bit” and call it done. Here is the tighter version:
- Original flour: 1 cup → 120 g.
- Halve the weight: 120 ÷ 2 = 60 g.
- If you have a scale, stop here and weigh 60 g.
- If you do not: measure ½ cup the spoon-and-level way, or use 8 level tablespoons.
- Check the other ingredients against weight, not volume — ¼ teaspoon of baking soda in a half batch is ¼ teaspoon, but ½ cup of chocolate chips goes to ¼ cup by volume while the flour went by weight. Do not mix the two methods in the same batch.
Notice step 5. The most common half-batch failure is not the flour at all — it is converting one ingredient by weight and the next by volume, which drifts the ratios apart. Pick a method and hold it across the whole ingredient list.
Scaling Up From Half a Cup
The same 60 g figure makes upward scaling easy. Doubling a half cup gives 1 cup, or 120 g. Tripling gives 1½ cups, or 180 g. Because weight is linear, you never have to ask whether ⅓ of ¾ cup plus a tablespoon equals anything — you just multiply the gram figure and read it back into cups at the end.
That matters most when the number of servings changes. If you are resizing a recipe rather than just doubling it, our Recipe Servings Calculator takes the original and target servings and rewrites each ingredient, flour included, so you never convert the same cup three times and lose a tablespoon along the way.
And when the flour amount grows, the batter grows with it. A half-cup-of-flour recipe usually bakes in a small pan; double it and you need either two pans or a bigger one. Our Baking Pan Converter compares pan areas and depths so you know whether to split the batter or move up a size before the cake domes and cracks.
Half a Cup in Grams: Quick Reference
- All-purpose: 60 g
- Bread flour: 65 g
- Cake flour: 57 g
- Whole wheat: 60 g
- Semolina: 84 g
- Rye: 51 g
- Almond flour: 48 g
The spread here is nearly 2:1 between almond flour and semolina. That is exactly why a single blanket rule — “a cup of flour is 240 g,” borrowed from water — fails so badly in baking. Flour is not water, and no two flours are the same flour.
