One millilitre of self-rising flour is 0.5283441 grams, so converting millilitres of self-rising flour to grams means multiplying by 0.5283441. That factor is specific to this ingredient — it comes from its density, not from any relationship between the two units.
Water is the yardstick: 1 mL of it weighs 1 g. Self-rising flour comes in at 0.52834 g per mL, or 52.83% of water, which is why a cup of it is 125 g rather than 236.6 g. Volume and weight only line up for water, and only in metric.
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.
What the number depends on: 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
millilitres- The amount of self-rising flour you are converting, in millilitres
0.528344104716- Grams per millilitre for self-rising flour, from its density of 0.52834 g/mL
grams- The equivalent quantity in grams
How it works, step by step
- Enter the quantity in millilitres.
- It is multiplied by 0.528344104716, the grams-per-millilitre figure for self-rising flour.
- The result appears in grams, with a second reading in oz beneath it.
- Use the measure table if you want a standard recipe quantity rather than a number you type in.
Worked examples
15 mL of self-rising flour in grams
15 mL of self-rising flour weighs out at 7.92516 grams. Divide 7.92516 by 0.5283441 and you get back to 15 mL, which is the quickest check that the factor is the right way up.
100 mL of self-rising flour in grams
100 mL of self-rising flour weighs out at 52.8344 grams. Divide 52.8344 by 0.5283441 and you get back to 100 mL, which is the quickest check that the factor is the right way up.
250 mL of self-rising flour in grams
A recipe calling for 250 mL of self-rising flour needs 132.086 grams on the scale. The arithmetic is 250 × 0.5283441 = 132.08603, and halving the recipe halves the weight to 66.043 grams.

Frequently asked questions
How many grams are in 1 mL of self-rising flour?
One millilitre of self-rising flour is 0.5283441 grams. Half that quantity is 0.264172 grams and double it is 1.05669 grams, 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 many millilitres of self-rising flour is 500 g?
500 g of self-rising flour is 946.35 millilitres — 1.89271 millilitres to one gram, so 500 × 1.89271 = 946.35. Going that way is a division by 0.528344, or a multiplication by 1.89271 if you prefer.
