Full API documentation

Explanation

Convert all-purpose flour teaspoons to grams with an ingredient-specific teaspoon reference derived from the shared cup basis.

The gram result stays more consistent than a generic teaspoon chart. 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.
