One gram of rye flour is 0.47058824 teaspoons, so converting grams of rye flour to teaspoons means multiplying by 0.47058824. That factor is specific to this ingredient — it comes from its density, not from any relationship between the two units.
Put next to water — 1 g per mL exactly — rye flour measures 0.43113 g per mL. That ratio, 43.11%, is what separates this page from every other ingredient in the same units, and it is measured rather than defined.
A level teaspoon of rye flour weighs 2.125 g. A kitchen scale that reads to the nearest gram is therefore working at roughly 47.1% resolution on a single spoonful, which is why measuring spoons beat scales below about 5 g and lose to them above it. Three teaspoons make a tablespoon, so the same spoonful is 6.375 g if the recipe scales up.
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
0.470588235294- Teaspoons per gram for rye flour, from its density of 0.43113 g/mL
teaspoons- The equivalent quantity in teaspoons
How it works, step by step
- Enter the quantity in grams.
- It is multiplied by 0.470588235294, the teaspoons-per-gram figure for rye flour.
- The result appears in teaspoons, with a second reading in mL 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 teaspoons
Take 50 g of rye flour: 50 × 0.47058824 gives 23.5294 teaspoons. Doubling the batch takes it to 47.0588 teaspoons, because the relationship is a straight proportion once the density is known.
150 g of rye flour in teaspoons
Take 150 g of rye flour: 150 × 0.47058824 gives 70.5882 teaspoons. Doubling the batch takes it to 141.176 teaspoons, because the relationship is a straight proportion once the density is known.
500 g of rye flour in teaspoons
500 g of rye flour weighs out at 235.294 teaspoons. Divide 235.294 by 0.47058824 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 teaspoons are in 1 g of rye flour?
One gram of rye flour is 0.47058824 teaspoons. Half that quantity is 0.235294 teaspoons and double it is 0.941176 teaspoons, 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 teaspoon of rye flour is 2.125 g, and a scale reading to the nearest gram is working at 47.1% 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 2 tsp of rye flour weigh?
2 tsp of rye flour comes to 4.25 g, or 4.25 grams. This page runs that calculation in reverse — enter a weight and it returns the volume — and the teaspoons-to-grams page does it in the direction the question is usually asked.
