Hemp Seeds: Grams to Cups
1 cup of hemp seeds = 160 grams
One US cup of hemp seeds weighs 160 grams. One 250 ml metric cup — the one used in the UK, Australia, New Zealand and Canada — holds 169 grams. To convert any weight, divide the grams by the figure for your cup.
Hulled hemp seeds (hemp hearts) are soft and oily; 160 g per cup is this site's working figure, not a published reference — package serving sizes of 3 tablespoons for 30 g imply about 160 g per cup.
Where the 160 g figure comes from
Neither USDA FoodData Central nor King Arthur Baking publishes a cup weight for hemp seeds, so 160 g is this site's working estimate. Weigh it when the result matters.

How to measure hemp seeds accurately
The 160 g figure assumes the spooned-and-levelled method: spoon the hemp seeds into a dry measuring cup and sweep the top flat with a straight edge. Scooping the cup through the bag compacts it and gives a heavier cup.
