How Much Is 1 Cup of Sunflower Seeds in Pounds?
1 cup of sunflower seeds weighs 0.31 lb. This is based on sunflower seeds having a density of 140g per cup. Because cups measure volume and pounds measure weight, the result depends on the ingredient, and a different ingredient would give a different result for the same 1 cup.
Formula and Step-by-Step
- Start with 1 cup of sunflower seeds
- 1 cup of sunflower seeds = 140g
- 1 × 140 = 140g
- Convert grams to pounds: 140 ÷ 453.592 = 0.31 lb
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.
