1/4 Cup Self-Rising Flour in Grams
1/4 cup of self-rising flour weighs 28.2 g (spooned and levelled, King Arthur Baking). All-purpose flour with baking powder and salt already mixed in. All the figures on this page are approximate conversions based on the King Arthur Baking value of 113 g per cup, so when a recipe really matters, verify with a kitchen scale.
Why a quarter cup is worth weighing
A quarter cup is a small measure, and small measures are where cup errors hurt most. A 5 g mistake in a full cup of self-rising flour is a rounding error; the same 5 g on a quarter cup is a 17 percent swing on 28.2 g, and in a small batch that swing can change the result. Recipes that call for a quarter cup are usually small, precise or both — a mug cake, a glaze, a roux, a single-serve bake — and there is no large batch to absorb the error. Weighing 28.2 g takes five seconds and removes the problem entirely.
Spooned and levelled is the method behind the number, and it matters. Self-Rising Flour is used for quick breads, scones, pancakes and biscuits. That range of uses is part of why the conversion comes up so often: the same ingredient appears in everyday cooking and in precise baking, and the two situations demand different levels of accuracy. Grams cut through all of that: 28.2 g of self-rising flour is 28.2 g whatever the brand, the humidity or the size of your measuring cup.

|---|---|---|
| 1/4 cup | 28.2 g | 4 |

| 1/2 cup | 56.5 g | 8 |
| 2/3 cup | 75.3 g | 10.7 |
| 3/4 cup | 84.8 g | 12 |
| 1 cup | 113 g | 16 |
| 1 1/2 cups | 169.5 g | 24 |
| 2 cups | 226 g | 32 |
The tablespoon column shows how many tablespoons each amount equals: a quarter cup is 4 tablespoons, and one tablespoon of self-rising flour weighs about 7.1 g. 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 1/4-cup row outwards: every other row is a multiple of 28.2 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 self-rising flour, that gives 113 g per cup, and a quarter of that is 28.2 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.
There is no serious dispute about this figure: King Arthur Baking lists 113 g per cup, and other reputable charts agree within a gram or two. The variation that remains comes from how the ingredient is measured, not from disagreement about the number itself.
Worked examples
Dredging fish fillets
Dredging two fish fillets takes about 1/4 cup of self-rising flour seasoned with salt and pepper — 28.2 g spread on a plate. The fillets pick up only a thin coating, and the rest stays on the plate, so the exact weight matters less than the coverage. Still, starting from 28.2 g means you are not hauling out the whole bag for a job that needs a handful, and you can season the flour evenly instead of guessing.
A crumble topping for one ramekin
A single-serve crumble for one ramekin needs about 1/4 cup of self-rising flour rubbed into butter with sugar. That is 28.2 g, and in a topping this small the flour-to-butter ratio is everything: too much flour and the topping is dusty and dry, too little and it melts into a greasy sheet. Weigh 28.2 g, rub in the cold butter until it looks like coarse breadcrumbs, and the topping bakes crisp instead of soggy.
A single-serve mug cake
Mug cakes are where quarter-cup measures live. A typical chocolate mug cake calls for 1/4 cup of self-rising flour, and because the whole cake is one serving, there is nowhere for a measuring error to hide. Spoon and level 28.2 g into the mug, stir in the cocoa, sugar and egg, and microwave. If you scoop straight from the bag instead, you can easily add 8 to 10 g extra, and in a mug cake that is enough to turn a soft sponge dry and rubbery. Weighing 28.2 g takes ten seconds and removes the guesswork entirely.
When a quarter cup is the whole recipe
Quarter-cup amounts usually appear in small or test batches, and that is exactly when accuracy matters most: a 5 g error in a 30 g measure is a 17 percent error, while the same 5 g in a full cup is barely 4 percent. Small recipes amplify mistakes. Weighing 28.2 g instead of eyeballing a quarter cup is the cheapest insurance in baking, and it is why professional bakers write recipes in grams even for tiny amounts.
Scaling a quarter cup up and down
Once you know that 1/4 cup of self-rising flour is 28.2 g, the rest is arithmetic. Half a cup is 56.5 g, three quarters is 84.8 g, and a full cup is 113 g. Doubling a recipe that calls for 1/4 cup means weighing 56.5 g; halving it means 14.1 g, which is 2 tablespoons. Writing the recipe in grams at this point is worth doing: the next time you make it, you weigh 28.2 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 self-rising flour
- Scooping the cup from the bag. Scooping packs the flour down and can add 20 g per cup — 5 g on a quarter cup. Always spoon and level, or weigh 28.2 g.
- Measuring over the mixing bowl. Levelling over the bowl drops the excess straight into the batter, so you have added flour you did not intend. Level over the bag or the sink.
- Using a liquid jug for flour. A jug measures volume at eye level and has no straight edge to level against, so flour measured in a jug is a guess. Use a dry cup or a scale.
- Sifting after measuring. Sifting changes the volume, not the weight. If a recipe says sifted flour, measure 28.2 g first, then sift it — never the other way round.
Storage and handling
Airtight container, cool and dry; use within 6 months so the raising agents stay active. Keeping self-rising 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 — 1/4 cup is 28.2 g — and the next person to bake with it will thank you.
Frequently asked questions
How many grams is 1/4 cup of self-rising flour?
1/4 cup of self-rising flour weighs 28.2 g, measured spooned and levelled according to King Arthur Baking. That is one quarter of the full-cup weight of 113 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 do I measure 1/4 cup of self-rising flour without a scale?
Self-Rising Flour is measured spooned and levelled, according to King Arthur Baking. Spooned and levelled it into a 1/4-cup measure, level the top with the back of a knife, and you will be close to 28.2 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 flour and removes the guesswork from every recipe, not just this one.
Is 1/4 cup of self-rising flour always 28.2 g?
No — 28.2 g is the standard value from King Arthur Baking for self-rising flour measured spooned and levelled, and it is the right default. Brand, moisture, how settled the container is and how firmly it was packed can shift the weight by a few grams. For most cooking that variation does not matter. For precise baking, weigh the ingredient and trust the scale over the cup.
What is self-rising flour used for?
Quick breads, scones, pancakes and biscuits. All-purpose flour with baking powder and salt already mixed in. A quarter cup — 28.2 g — is a common amount in small batches, glazes, sauces and test bakes, which is why this conversion comes up so often.
How should I store self-rising flour?
Airtight container, cool and dry; use within 6 months so the raising agents stay active. 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.
