Measurement Conversions & Ingredient Substitutions

Two tables a cook reaches for again and again: the one that translates a recipe written in grams into cups, and the one that tells you what to reach for when the cupboard is short of one ingredient. Keep this page close to the stove — it is the quiet half of cooking.

Measurement conversion tables

Close, not exact: 28 g to the ounce and 240 ml to the cup are the working approximations behind these tables. Where a recipe gives both weight and volume, follow the weight.
