Where 168 g comes from
USDA FoodData Central: 1 cup, whole of “Seeds, flaxseed” = 168 g. FDC 169414
King Arthur Baking ingredient weight chart (“Flaxseed”): 140 g per cup. Chart
This page uses 168 g (USDA). The two sources differ by 28 g (16.7%): that gap is about how firmly the cup is filled, not an error in either.
Whole flaxseed weighs 168 g a cup in USDA's data and King Arthur's ¼ cup at 35 g gives 140 g. Ground flax meal is much lighter, about 100 g a cup.
How to measure whole flaxseed by the cup
Fill the cup, give it a shake so the pieces settle, and level the top with your hand. Don't press down.
In the UK and Australia: linseed. Metric cups there hold 250 ml, so a metric cup of whole flaxseed weighs about 178 g.
