Grams of rye flour to millilitres runs on one number, 2.3194925 millilitres per gram. It is a measured property of this ingredient rather than a defined conversion, which is why a generic volume-to-weight tool cannot give you it.
Water is the yardstick: 1 mL of it weighs 1 g. Rye flour comes in at 0.43113 g per mL, or 43.11% of water, which is why a cup of it is 102 g rather than 236.6 g. Volume and weight only line up for water, and only in metric.
Rye flour has a density of 0.43113 g per mL, so 100 mL of it weighs 43.11 g and 250 mL weighs 107.8 g. That single figure is what every other number on this page is built from — water is 1.00 g per mL, so this ingredient is 43.11% as heavy as the same volume of water.
Grams are the unit this conversion is really for. A domestic scale resolves to a gram, which is 0.98% of a cup of rye flour, so weighing gets an accuracy no measuring cup can reach. A 500 g pack of it is 4.902 cups, and a 1 kg pack 9.804.
What the number depends on: One of the lightest flours per cup. Rye has little gluten to develop, so it is almost always blended with wheat flour.
The formula
grams- The amount of rye flour you are converting, in grams
2.31949251471- Millilitres per gram for rye flour, from its density of 0.43113 g/mL
millilitres- The equivalent quantity in millilitres
How it works, step by step
- Enter the quantity in grams.
- It is multiplied by 2.31949251471, the millilitres-per-gram figure for rye flour.
- The result appears in millilitres, with a second reading in tsp beneath it.
- Use the measure table if you want a standard recipe quantity rather than a number you type in.
Worked examples
50 g of rye flour in millilitres
50 g of rye flour weighs out at 115.975 millilitres. Divide 115.975 by 2.3194925 and you get back to 50 g, which is the quickest check that the factor is the right way up.
150 g of rye flour in millilitres
A recipe calling for 150 g of rye flour needs 347.924 millilitres on the scale. The arithmetic is 150 × 2.3194925 = 347.92388, and halving the recipe halves the weight to 173.962 millilitres.
500 g of rye flour in millilitres
Take 500 g of rye flour: 500 × 2.3194925 gives 1159.75 millilitres. Doubling the batch takes it to 2319.49 millilitres, because the relationship is a straight proportion once the density is known.

Frequently asked questions
How many millilitres are in 1 g of rye flour?
One gram of rye flour is 2.3194925 millilitres. Half that quantity is 1.15975 millilitres and double it is 4.63899 millilitres, so the figure scales straight up and down — there is no offset in this conversion, only the factor.
Why is a cup of rye flour not 236 g like water?
Because weight per cup depends on what is in the cup. Rye flour has a density of 0.43113 g per mL where water has 1.00, so a cup of it weighs 102 g rather than 236.6 g. That is a difference of 134.6 g per cup, and it is the reason a single volume-to-weight factor cannot be applied to every ingredient.
Does how I measure it change the weight?
Yes, and by more than most people expect. Handling changes the weight of a cup of rye flour by roughly 20% — about 10.2 g either side of 102 g — because one of the lightest flours per cup. Weighing removes the question entirely.
Is a fluid ounce of rye flour the same as an ounce?
No. A fluid ounce is a volume — one eighth of a US cup, 29.57 mL — and an ounce is a weight. One fluid ounce of rye flour weighs 0.4497 oz, so the two readings differ by 55%. They coincide only for something with the density of water, and then only roughly.
Is this a US cup or a metric cup?
US customary: 236.59 mL, which is the cup every US recipe means. A metric cup is 250 mL, so the same cup of rye flour would weigh 107.78 g instead of 102 g — 5.78 g more, or 5.67%. Australian and some European recipes use the metric cup, and the difference is large enough to matter in baking.
Do I need a scale for this, or will measuring cups do?
At this size the spoon wins. One millilitre of rye flour is 0.4311 g, and a scale reading to the nearest gram is working at 232% resolution on that — a measuring spoon is the more accurate instrument below about 5 g, which is why spice quantities are still written in spoons.
How much does 15 mL of rye flour weigh?
15 mL of rye flour comes to 6.4669 g, or 6.4669 grams. This page runs that calculation in reverse — enter a weight and it returns the volume — and the ml-to-grams page does it in the direction the question is usually asked.
