One gram of rye flour is 0.15686275 tablespoons, so converting grams of rye flour to tablespoons means multiplying by 0.15686275. That factor is specific to this ingredient — it comes from its density, not from any relationship between the two units.
The density behind that figure is 0.43113 g per mL, against 1.00 for water. A cup of water weighs 236.6 g and a cup of rye flour weighs 102 g, so this ingredient is 43.11% as heavy as the same volume of water — the single fact the whole page rests on.
A level tablespoon of rye flour is 6.375 g, which puts a teaspoon at 2.125 g and a tablespoon and a half — the quantity recipes are fondest of — at 9.562 g. Levelling twice is where the error comes from, so the scale is the faster instrument once the quantity passes a couple of spoons.
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
0.156862745098- Tablespoons per gram for rye flour, from its density of 0.43113 g/mL
tablespoons- The equivalent quantity in tablespoons
How it works, step by step
- Enter the quantity in grams.
- It is multiplied by 0.156862745098, the tablespoons-per-gram figure for rye flour.
- The result appears in tablespoons, 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 tablespoons
Take 50 g of rye flour: 50 × 0.15686275 gives 7.84314 tablespoons. Doubling the batch takes it to 15.6863 tablespoons, because the relationship is a straight proportion once the density is known.
150 g of rye flour in tablespoons
150 g of rye flour weighs out at 23.5294 tablespoons. Divide 23.5294 by 0.15686275 and you get back to 150 g, which is the quickest check that the factor is the right way up.
500 g of rye flour in tablespoons
500 g of rye flour weighs out at 78.4314 tablespoons. Divide 78.4314 by 0.15686275 and you get back to 500 g, which is the quickest check that the factor is the right way up.

Frequently asked questions
How many tablespoons are in 1 g of rye flour?
One gram of rye flour is 0.15686275 tablespoons. Half that quantity is 0.0784314 tablespoons and double it is 0.313725 tablespoons, 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 tablespoon of rye flour is 6.375 g, and a scale reading to the nearest gram is working at 15.7% 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 3 tbsp of rye flour weigh?
3 tbsp of rye flour comes to 19.125 g, or 19.125 grams. This page runs that calculation in reverse — enter a weight and it returns the volume — and the tablespoons-to-grams page does it in the direction the question is usually asked.
