How Much Is 1.63 Ounces of Sunflower Seeds in Cups?
1.63 ounces of sunflower seeds equals 0.33 cups. That's 46.21g, and Sunflower seeds has a density of 140g per cup. Because ounces measure weight and cups measure volume, the result depends on the ingredient's density.
Formula and Step-by-Step
- Start with 1.63 ounces of sunflower seeds
- Convert ounces to grams: 1.63 × 28.35 = 46.21g
- 1 cup of sunflower seeds = 140g
- 46.21g ÷ 140g/cup = 0.33 cups
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
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 an Ounce?
An ounce (oz) is a US customary unit of weight equal to 28.3495 grams or 1/16 of a pound. In cooking, "ounces" refers to weight (avoirdupois ounces), not fluid ounces which measure volume.
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.
