How this conversion is calculated

Volume-to-weight conversions are only as good as the density behind them. We treat tapioca starch as 120 g per US customary cup, which works out to 0.507 g/ml. From there:

  1. Your teaspoons figure is converted into millilitres or grams using standard unit sizes (tsp = 4.93 ml).
  2. The density above bridges volume and weight in whichever direction you need.
  3. The result is rounded the way a cook would round it — to the nearest gram, or to a usable fraction such as 7/8 cups.

Measuring tapioca starch accurately

Tapioca starch and tapioca flour are the same product; both are very light and static-prone.

If a recipe matters to you — bread, macarons, anything with a tight hydration or ratio — weigh it. A £10 digital scale removes the single largest source of variation in home baking, and it is faster than washing three measuring cups.

When cups are fine

  • Liquids measured in a proper jug, where volume is the honest unit anyway.
  • Forgiving savoury cooking: soups, stews, stir-fries, marinades.
  • Small amounts of leaveners and spices, as long as you use level spoons.
