1 ounce (about 28.3 grams) of chopped pecans is roughly 0.26 cups, close to a quarter cup.

Does this figure apply to whole or halved pecans?

This tool uses the density for chopped pecans. Pecan halves take up more air between pieces and can weigh less per cup, so treat this as an estimate for whole halves.

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 hold slightly more grams for the same cup measurement.

Can I convert cups back to grams?

Yes. Multiply your cup amount by 110 to get the equivalent weight in grams.

Why do gram-to-cup conversions vary between sources?

Nut density depends on how finely the pecans are chopped and how tightly they are packed into the cup. 110 g/cup is a commonly cited baking-reference figure for chopped pecans.
