Grams of self-rising flour to millilitres runs on one number, 1.8927059 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.
The density behind that figure is 0.52834 g per mL, against 1.00 for water. A cup of water weighs 236.6 g and a cup of self-rising flour weighs 125 g, so this ingredient is 52.83% as heavy as the same volume of water — the single fact the whole page rests on.
Self-rising flour has a density of 0.52834 g per mL, so 100 mL of it weighs 52.83 g and 250 mL weighs 132.1 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 52.83% 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 0.8% of a cup of self-rising flour, so weighing gets an accuracy no measuring cup can reach. A 500 g pack of it is 4 cups, and a 1 kg pack 8.
How the figure is arrived at: The same weight per cup as all-purpose, because that is what it is — with baking powder and salt already blended through it.
The formula
grams- The amount of self-rising flour you are converting, in grams
1.892705892- Millilitres per gram for self-rising flour, from its density of 0.52834 g/mL
millilitres- The equivalent quantity in millilitres
How it works, step by step
- Enter the quantity in grams.
- It is multiplied by 1.892705892, the millilitres-per-gram figure for self-rising 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 self-rising flour in millilitres
A recipe calling for 50 g of self-rising flour needs 94.6353 millilitres on the scale. The arithmetic is 50 × 1.8927059 = 94.635295, and halving the recipe halves the weight to 47.3176 millilitres.
150 g of self-rising flour in millilitres
Take 150 g of self-rising flour: 150 × 1.8927059 gives 283.906 millilitres. Doubling the batch takes it to 567.812 millilitres, because the relationship is a straight proportion once the density is known.
500 g of self-rising flour in millilitres
A recipe calling for 500 g of self-rising flour needs 946.353 millilitres on the scale. The arithmetic is 500 × 1.8927059 = 946.35295, and halving the recipe halves the weight to 473.176 millilitres.

Frequently asked questions
How many millilitres are in 1 g of self-rising flour?
One gram of self-rising flour is 1.8927059 millilitres. Half that quantity is 0.946353 millilitres and double it is 3.78541 millilitres, so the figure scales straight up and down — there is no offset in this conversion, only the factor.
Why is a cup of self-rising flour not 236 g like water?
Because weight per cup depends on what is in the cup. Self-rising flour has a density of 0.52834 g per mL where water has 1.00, so a cup of it weighs 125 g rather than 236.6 g. That is a difference of 111.6 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 self-rising flour by roughly 20% — about 12.5 g either side of 125 g — because the same weight per cup as all-purpose, because that is what it is — with baking powder and salt already blended through it. Weighing removes the question entirely.
Is a fluid ounce of self-rising 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 self-rising flour weighs 0.5512 oz, so the two readings differ by 44.9%. 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 self-rising flour would weigh 132.09 g instead of 125 g — 7.09 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 self-rising flour is 0.5283 g, and a scale reading to the nearest gram is working at 189% 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 self-rising flour weigh?
15 mL of self-rising flour comes to 7.9252 g, or 7.9252 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.
