Cups to grams ingredient converter
Convert cups, tablespoons, teaspoons, grams, and ounces using weights for 12 common baking ingredients.
Decimals and fractions work: 1.5, 1 ½, or 3/4.

Scoop, measure, repeat
Try a cup measure, then add another half cup. The quantity and conversion update together.
1.5 cups of all-purpose flour → 180 g.
The illustration accompanies the results below. Illustrations are schematic.
Converted quantity
180 g
1.5 cups of all-purpose flour.
Reference: 120 g per cup. Amounts are approximate; prefer the gram weight supplied by your recipe.
Cup-to-weight conversions depend on the ingredient and how it is measured. A cup of flour and a cup of sugar weigh different amounts. Here, one cup is 16 US tablespoons or 48 US teaspoons; metric and Australian cup measures differ.

Convert the ingredient, not just the unit
A volume-to-weight conversion needs a weight for the chosen ingredient. The tool first converts your amount to grams using its reference portion, then converts grams to your selected output unit. Cup and spoon measures here follow US recipe proportions. Ounces mean weight, not fluid ounces.
Worked example
1½ cups of all-purpose flour becomes 180 g using a 120 g-per-cup reference. One cup of granulated sugar becomes 198 g. These are reference estimates, not measurements of your own cup.
Why does another recipe use a different gram weight?
Brands, packing, sifting, and rounding can change the weight of a measured cup. Use the gram quantity in the recipe when it supplies one, and follow the preparation specified for packed or sifted ingredients.
