How many cups is 168 grams of flax seeds?

About 1 cup, since a cup of whole flax seeds weighs approximately 168 grams.

How many cups is 100 grams of flax seeds?

About 0.6 cups, using the standard density of 168 grams per cup.

Does this figure apply to ground flaxseed (flax meal)?

No. Ground flaxseed is less dense than whole flax seeds because grinding introduces air, so it weighs less per cup. This tool is calibrated for whole, unground flaxseed.

Is this the same for brown and golden flaxseed?

Yes, brown and golden flaxseed have essentially the same density, so the same 168 g/cup figure applies to both.

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 lower cup result for the same gram amount.
