Cake Flour grams to cups
One US cup of cake flour weighs about 114 grams.
A low-protein flour milled very finely and usually bleached, which weakens gluten and produces a tender, close crumb. The fine grind makes it lighter in the cup than all-purpose despite feeling denser in the hand.

Cake Flour in tablespoons, teaspoons and millilitres

One US cup is 16 tablespoons or 48 teaspoons, whatever is in it — those two are volume measures, so no density is involved.
How you measure it changes the weight
Most converters publish a single number. In practice the technique matters, so here is what a cup weighs depending on how it was filled.
| Method | 1 cup weighs | What that means |
|---|---|---|
| Sifted | 100 g | Sifted into the cup, then levelled without tapping or pressing. |
| Spooned & levelled default | 114 g | Spooned into the cup, then levelled with a straight edge. The method a recipe means by "1 cup cake flour". |
Measuring notes
Cake flour clumps readily, so sift it before measuring if the recipe calls for sifted. It is the flour where the gap between sifted and spooned matters most, because the whole point of using it is a delicate texture.

Cake Flour — common questions
How many cups is 100 grams?
It depends entirely on the ingredient. 100 grams of all-purpose flour is about 0.83 cups, but 100 grams of honey is only about 0.29 cups, because honey is far denser. Grams measure weight and cups measure volume, so there is no single conversion that works for everything.
Why do different converters give different answers?
Mostly because they assume different measuring techniques. Flour spooned gently into a cup weighs around 120 grams; the same cup dipped straight into the bag can hold 140 grams. Both figures are defensible, so two sites can disagree by 15% and neither is lying. We publish separate figures for each technique rather than picking one.
Are these conversions exact?
No, and no weight-to-volume conversion can be. Density shifts with packing, humidity, grind and brand. Treat every result here as a close approximation. If precision matters, weigh your ingredients.
Should I use grams or cups?
Grams, whenever you have a scale. Weight does not change with how you fill the cup, so it is reproducible, and weighing straight into the bowl means less washing up. Cups are convenient, not accurate.
Which cup size do you use?
The US cup, 236.6 millilitres. A metric cup is 250 ml and an imperial cup is about 284 ml, so if you are following a British or Australian recipe our figures will run slightly small.
