1/3 Cup Rye Flour in Grams
If you need 1/3 cup of rye flour in grams, weigh out 35.3 g. That is the King Arthur Baking figure for rye flour measured spooned and levelled: a full cup weighs 106 g, and a third of a cup of that is 35.3 g. Medium rye flour with a distinctive earthy, slightly sour flavour. Treat every figure here as approximate and verify with a kitchen scale when the result matters.
Why this small amount trips people up
The trouble with 1/3 cup is that it is small enough to eyeball and large enough for the error to matter. A cup scooped from the bag can hold noticeably more than a cup spooned and levelled, and on 35.3 g that difference is a real percentage. Weighing takes the guesswork out, and it is faster than levelling a cup properly.
Worked examples
Doubling and halving from 1/3 cup
Halving a recipe is where 1/3 cup appears most often in real kitchens. A recipe written for a family might call for 1 1/2 cups of rye flour; halved, that is 1/3 cup, or 35.3 g. The trap is halving by volume: half of 1 1/2 cups is easy to say and hard to measure, because few cup sets have a 3/4-cup measure and fewer still have a 1/3-cup one. Weighing 35.3 g sidesteps the problem entirely. And if you are doubling instead, two lots of 1/3 cup is 1 1/2 cups, which is 70.7 g — again, one number on the scale, no cup juggling, and the recipe stays in proportion.
Scaling a recipe that calls for 1/3 cup
A recipe for a layer cake calls for 1/3 cup of rye flour, and you want to make one and a half times as much for guests. On the scale that is simple: 35.3 g times 1.5 is 53 g, and you weigh it straight into the bowl. Doing the same sum in cups means measuring a cup and an eighth, which no measuring cup marks, so most people guess — and guessing is how a good recipe goes wrong. The same logic works in reverse: halve the recipe and you need 17.7 g, which is 17.7 g on the scale and a fiddly 2.6 tablespoons by volume. rye flour is used for rye breads, crackers and gingerbread, and the weighed amount keeps the ratio right at any scale.
A small batch built around 1/3 cup
Sometimes 1/3 cup is the whole point of the recipe, not a fraction of it. A small batch of a batch of morning muffins for two people often needs just 1/3 cup of rye flour — 35.3 g — alongside the other ingredients, and at that scale there is nothing to hide behind: too much and the result is heavy or overpowering, too little and it is bland or falls apart. Weigh the 35.3 g first, before you start mixing, so you know the foundation is right. Once you know that 1/3 cup is 35.3 g, you can scale the same recipe up for four people by doubling to 70.7 g without ever touching a measuring cup, and the result will taste the same.

The tablespoon column shows how many tablespoons each amount equals: 1/3 cup is 5.3 tablespoons, and one tablespoon of rye flour weighs about 6.6. A cup is 16 tablespoons, so the numbers in the table are just the cup weight divided by 16, rounded to one decimal place. For small amounts a scale that reads to the gram is far more reliable than a spoon, because a heaped tablespoon can weigh half as much again as a level one. Read the table from the 1/3 cup row outwards: every other row is a multiple of 35.3 g, so scaling a recipe up or down is simple multiplication.
How the weight was measured
Spooned and levelled means the ingredient is measured the way King Arthur Baking measures it: spooned and levelled. For rye flour, that gives 106 g per cup, and a third of a cup of that is 35.3 g. The source for the figure is King Arthur Baking, and the confidence in the value is high. King Arthur Baking publishes a standard ingredient weight chart that recipe developers use as a reference, and this page follows it exactly rather than averaging across sources, because an average of two different measuring methods is a number that matches nobody's cup.
Practical guidance for rye flour
Flour is the ingredient where measuring method matters most, and a third of a cup is small enough for a bad technique to ruin the ratio. Scooping the cup straight from the bag packs the flour down and can add a fifth to the weight; spooning it in loosely and levelling with a knife gives the figure used on this page, 106 per cup from King Arthur Baking, and a third of that is 35.3. That single technique — spoon and level — is worth learning properly, because it applies to every flour on this site. Sifting changes volume, not weight, so if a recipe calls for sifted flour, weigh 35.3 first and sift it afterwards. Flour also absorbs moisture from the air, so a bag left open in a humid kitchen will weigh more per cup than a fresh one, and the scale is the only tool that tells you the truth.
When the conversion matters most
1/3 cup of rye flour shows up in recipes where the ratio is doing real work. rye flour is used for rye breads, crackers and gingerbread, and in those recipes the amount is not decoration — it sets the texture, the structure or the flavour balance. In a sauce or a dressing, a few extra grams of rye flour can tip the balance; in a baked good, they can change the crumb. That is why recipes written in grams are worth following in grams: the recipe writer tested 35.3 g, not a cup that happened to be full that day. If you are cooking by feel, a cup is fine; if you are baking to a recipe, weigh it. The difference between the two approaches is the difference between a recipe that works every time and one that works on a good day.
Scaling 1/3 cup up and down
Once you know that 1/3 cup of rye flour is 35.3 g, the rest is arithmetic. A full cup is 106 g, half a cup is 53 g, and two cups is 212 g. Doubling a recipe that calls for 1/3 cup means weighing 70.7 g; halving it means 17.7 g, which is about 2.6 tablespoons. Writing the recipe in grams at this point is worth doing: the next time you make it, you weigh 35.3 g straight into the bowl and skip the measuring cup altogether. If you are scaling a recipe for a different tin size, convert every ingredient to grams first and then multiply — scaling by volume compounds the error on every ingredient at once, while scaling by weight keeps each one exact.
Common mistakes with rye flour
- Using a liquid jug for a dry ingredient. A jug measures volume at eye level and has no straight edge to level against, so rye flour measured in a jug is a guess. Use a dry cup or a scale.
- Scooping the cup from the bag. Scooping packs the flour down and can add several grams even to a third of a cup. Always spoon and level, or weigh 35.3.
- Sifting after measuring. Sifting changes the volume, not the weight. If a recipe says sifted rye flour, measure 35.3 g first, then sift it — never the other way round.
- Measuring over the mixing bowl. Levelling over the bowl drops the excess straight into the batter. Level over the bag or the sink.
Storage and handling
Airtight container, cool and dry; refrigerate for longer keeping. Keeping rye flour stored properly also keeps its weight per cup stable: an ingredient that has absorbed moisture from the air weighs more per cup than a dry one, so a sealed container is not just about freshness, it is about measurement accuracy too. If a bag has been open for months in a humid kitchen, the first thing to do before a precise bake is to weigh the ingredient rather than trusting the cup. Label the container with the conversion — 1/3 cup is 35.3 g — and the next person to bake with it will thank you.
Frequently asked questions
How many grams is 1/3 cup of rye flour?
1/3 cup of rye flour weighs 35.3 g, measured spooned and levelled according to King Arthur Baking. That is a third of a cup of the full-cup weight of 106 g, and it is the figure to use when converting a recipe from cups to grams. All the figures on this page are approximate, so when a recipe really matters, verify with a kitchen scale.
How many tablespoons is 1/3 cup of rye flour?
There are 5.3 tablespoons in 1/3 cup, whatever the ingredient. One tablespoon of rye flour weighs about 6.6, so 5.3 tablespoons come to about 35.3 g. For amounts like this, a scale that reads to the gram is more reliable than spoons, because a heaped tablespoon can weigh half as much again as a level one.
How do I measure 1/3 cup of rye flour without a scale?
Rye flour is measured spooned and levelled, according to King Arthur Baking. Spoon it into a 1/3 cup measure, level the top with the back of a knife, and you will be close to 35.3 g. That is the best you can do without a scale — but be honest with yourself that it is an estimate. A basic digital kitchen scale costs less than a bag of good ingredients and removes the guesswork from every recipe, not just this one.
What is rye flour used for?
Rye breads, crackers and gingerbread. Medium rye flour with a distinctive earthy, slightly sour flavour. 1/3 cup — 35.3 g — is a common amount in small batches and scaled recipes, which is why this conversion comes up so often.
How should I store rye flour?
Airtight container, cool and dry; refrigerate for longer keeping. Good storage keeps the ingredient fresh and keeps its weight per cup consistent, because moisture absorbed from the air adds grams that the recipe did not ask for.
Can I scale a recipe that uses 1/3 cup of rye flour?
Yes — convert to grams first, then multiply. 1/3 cup is 35.3 g, a full cup is 106 g, and two cups is 212 g, so doubling means 70.7 g and halving means 17.7 g. Scaling by weight keeps every ingredient in proportion, while scaling by volume compounds the error on each one.
