Cup measures are convenient until you scale them. Half of ¾ cup is manageable; 1.7 times ⅔ cup is not. Converting a recipe to grams before scaling gives every line the same simple operation: multiply the weight. This table uses a US 240 ml cup and spoon-and-level technique for powders.

The scaling ratio

Convert the original cup measure to grams, then multiply by the scaling factor. For example, 1½ cups all-purpose flour is about 180 g; scaled ×1.5, it becomes 270 g.

How to use the table

  1. Convert the original volume into grams one ingredient at a time.
  2. Multiply the grams by your scale factor.
  3. Round sensible amounts: flour to the nearest 5 g, spices more tightly.
  4. If the recipe author gives grams, use their grams over any generic chart.

Worked example: 1.5× oatmeal cookies

Original: 1½ cups flour · 1 cup oats · ½ cup butter · ¾ cup brown sugar.

Convert first: 180 g flour · 90 g oats · 113 g butter · 160 g brown sugar. Scale ×1.5: 270 g flour · 135 g oats · 170 g butter · 240 g brown sugar.

Why charts disagree

  • Scooped flour can weigh far more than spooned flour, so technique matters.
  • A recipe's own gram weights beat any outside chart because the author tested with those numbers.
  • Cup size differs by country. This site uses the US 240 ml cup.
  • Very small amounts like baking soda should stay in teaspoons unless your scale reads tenths of a gram accurately.
Kitchen noteThe calculator uses the same house table for recognized ingredients and shows approximate grams beside practical cup measures.

Skip the long division. Paste your ingredient list into the scaling pot and get every line converted at once.
