Rice Flour grams to cups
One US cup of rice flour weighs about 158 grams.
Finely milled rice, used in gluten-free baking, tempura batter and as a crisping agent. The hard grain grinds to a dense, sandy powder that weighs more per cup than wheat flour.

One US cup is 16 tablespoons or 48 teaspoons, whatever is in it — those two are volume measures, so no density is involved.
Measuring notes
Rice flour does not absorb liquid the way wheat does and will settle out of a batter. Whisk again just before using.

Rice 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.
