Grams to Cups: Sunflower Seeds
If your recipe is written in cups but your scale reads grams — or the other way round — this page solves the conversion for sunflower seeds. One cup of sunflower seeds weighs about 140 grams, which works out to a density of 0.59 g/ml. From there, half a cup is roughly 70 g, a quarter cup about 35 g, and one tablespoon about 9 g.
Converting between weight and volume depends on density, and density is specific to each ingredient: a cup of sunflower seeds does not weigh the same as a cup of flour or sugar. That is why this tool uses the measured density of sunflower seeds, taken from the USDA FoodData Central database, rather than a one-size-fits-all figure.
