How many grams are in a cup of pecans?

A cup of chopped pecans is about 110 grams, which is roughly 3.88 ounces.

How many grams are in a 1/4 cup of pecans?

A quarter cup of chopped pecans weighs about 28 grams, using the 110 grams per cup density.

Does this figure apply to pecan halves or whole pecans?

This tool uses the density for chopped pecans. Pecan halves pack less densely by volume, so a cup of halves typically weighs a bit less than 110 grams.

Is this the same as 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.

Can I convert grams back to cups?

Yes. Divide your gram amount by 110 to get the equivalent number of cups of chopped pecans.
