Explanation

This page answers the practical spoon question directly: how much 1 teaspoon of all-purpose flour weighs in grams. It uses one ingredient-specific teaspoon factor derived from the same base cup assumption used across the family.

That makes the result more consistent than mixing generic spoon charts. That is especially useful for baking and dough work, where small differences in flour volume can change hydration and texture. All-purpose Flour can vary with milling, aeration, and scoop style, so the page keeps one explicit basis instead of mixing spooned, packed, and sifted outcomes.

Method & Spoon Basis

  • Method basis: teaspoon-to-weight conversion derived from 120 g per 1 US cup.
  • Applied formula: grams = teaspoons × 2.5.
  • Consistency rule: snapshot, calculator, FAQ, and table use the same ingredient-specific basis.
