How many grams are in a cup of peanuts?

A cup of shelled peanuts weighs about 146 grams, which is roughly 5.15 ounces. This figure applies to whole raw or dry-roasted peanuts.

How many grams are in a tablespoon of peanuts?

Since there are 16 tablespoons in a cup, one tablespoon of shelled peanuts weighs about 9.13 grams using the same 146 g/cup density.

Is 146 grams per cup an exact figure?

No, it is an approximation. Peanut size, moisture content, and how tightly the nuts settle in the cup all affect the actual weight. For baking where precision matters, weigh the peanuts on a kitchen scale instead of relying on a cup measure.

Does chopping the peanuts change the weight per cup?

Yes. Chopped peanuts break into smaller, irregular pieces that do not pack the same way whole nuts do, so a cup of chopped peanuts can weigh noticeably less than a cup of whole peanuts. This tool uses the whole-peanut figure.

Does roasting change the weight?

Roasting removes a small amount of moisture, so dry-roasted peanuts weigh close to but slightly less than raw peanuts per cup. The 146 g/cup figure is a standard reference 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.

Quick Reference Table

Cups	Grams	Ounces

Values are measured by US cup (236.6 ml) using a density of 146 grams per cup of shelled raw or dry-roasted peanuts. This is an approximation: peanut size, moisture, and settling in the cup all shift the real weight, and chopped peanuts weigh less per cup than whole ones.
