How many grams are in a cup of pumpkin seeds?

A cup of shelled pumpkin seeds (pepitas) weighs about 140 grams, which is roughly 4.94 ounces.

How many grams are in a tablespoon of pumpkin seeds?

Since there are 16 tablespoons in a cup, one tablespoon of shelled pumpkin seeds weighs about 8.75 grams using the same 140 g/cup density.

Does this figure apply to in-shell pumpkin seeds?

No. This 140 g/cup density is for shelled, hulled pumpkin seeds (pepitas). Whole in-shell pumpkin seeds are lighter and bulkier per cup because of the hulls, so they weigh less per cup.

Does roasting change the weight?

Roasting removes a small amount of moisture, so roasted pumpkin seeds weigh slightly less per cup than raw ones. The 140 g/cup figure is a standard average suitable for most recipes.

Is this a US cup or a metric cup?

This tool uses the US cup (236.6 ml). A metric cup (250 ml) would give a slightly higher gram result.
