Tapioca Starch/Flour: US Cups & tbsp to Grams (g) & Ounces (oz) Conversion
Convert volumes of tapioca starch (also known as tapioca flour) measured in US cups and tablespoons (tbsp) to its approximate weight in metric grams (g) and imperial/US ounces (oz). Often used in gluten-free baking and as a thickener.

Important Considerations for Tapioca Starch/Flour:
Tapioca starch is a fine, light powder derived from the cassava root. Its weight per volume can vary. A common average is around **120-125 grams per US cup** (approximately 4.2-4.4 ounces) when spooned and leveled.
Do not pack tapioca starch into the measuring cup unless specified by the recipe. Use the "spoon and level" method.
It is a popular gluten-free thickener and is used in baking to add chewiness and a slightly crisp crust.
For consistent results in gluten-free baking or when used as a primary thickener, measuring by weight with a kitchen scale is recommended.
