Measuring Tip
Sunflower seeds are small and pack tightly. Pour them into the measuring cup and level off without shaking, which settles the seeds and increases the weight.
Understanding the Units
What is a Cup?
In US cooking, a cup measures volume, not weight. One standard US cup holds 236.588 ml of liquid. Because different ingredients have different densities, a cup of one ingredient can weigh very differently from a cup of another.
What is a Pound?
The abbreviation "lb" comes from the Latin word "libra." One pound equals exactly 453.59237 grams. For rough mental math, 1 pound is slightly less than half a kilogram.

The most accurate way is to weigh sunflower seeds on a kitchen scale. If you are measuring by volume, spoon the ingredient into the measuring cup and level it off with a straight edge rather than scooping directly from the container, which packs more in and gives a heavier result.
Close, but not exactly. The cups to pounds conversion for sunflower seeds may vary slightly between brands depending on moisture content and how the ingredient is measured.
Weighing is more consistent than volume measuring. A cup of sunflower seeds can vary by 10-20% depending on how it's scooped, packed, or leveled. Weighing gives the same result every time, which is especially important in baking where precision affects texture and rise.
