Cassava Flour: Cups to Grams
1 cup of cassava flour weighs about 120 g. Half a cup is 60 g, a tablespoon about 7.5 g, and a full cup is 4.23 ounces on a scale.
💡 Tip: Cassava flour is the closest gluten-free flour to a 1:1 wheat swap in many recipes. It's the whole ground root — not the same as tapioca starch, which is extracted.

Cassava flour vs tapioca starch
Cassava flour is the whole cassava root, peeled, dried and ground — which makes it one of the closest gluten-free, grain-free flours to a 1:1 wheat swap in many recipes. It weighs about 120 g per cup. Don't confuse it with tapioca starch (or tapioca flour), which is only the starch extracted and washed out of the same root; the two behave very differently and aren't interchangeable. Cassava is also the base of Brazilian pão de queijo and West African fufu and garri.
Because it's so absorbent, start near a 1:1 swap and add liquid gradually until the batter looks right.

There are 16 tablespoons in a cup, so one tablespoon of cassava flour weighs roughly 7.5 g — and a teaspoon 2.5 g.
Cassava Flour against the other flours & starches
120 g per cup places cassava flour in the middle of its category — lighter than self-rising flour (125 g) and heavier than '00' flour (116 g).
It weighs the same per cup as all-purpose flour (120 g), so those two swap one-for-one whether you measure by cup or by scale.

- Can I substitute cassava flour 1:1 for wheat flour?
- Often, yes — it's one of the closest grain-free swaps. Because it's very absorbent, start at 1:1 and add extra liquid little by little until the texture matches.
- Is cassava flour gluten-free?
- Yes. Cassava flour is made purely from the cassava root, with no wheat or grain, so it's naturally gluten-free and grain-free.
