1 cup of rye flour = 102 grams
One US cup of rye flour weighs 102 grams. One 250 ml metric cup — the one used in the UK, Australia, New Zealand and Canada — holds 108 grams. To convert any weight, divide the grams by the figure for your cup.
Medium rye flour weighs 102 g per cup (USDA FoodData Central; King Arthur Baking gives 106 g). Dark rye and pumpernickel flour are heavier — USDA lists 128 g — because they keep more of the bran.

How to measure rye flour accurately
The 102 g figure assumes the spooned-and-levelled method: spoon the rye flour 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.
- 1 US cup of rye flour = 102 g
- 1 metric cup (250 ml) of rye flour = 108 g
- ¾ cup = 77 g
- ½ cup = 51 g
- ⅓ cup = 34 g
- ¼ cup = 26 g
- 1 tablespoon = 6.4 g
