To convert grams of self-rising flour into tablespoons, multiply by 0.128: one gram comes to 0.128 tablespoons. Every ingredient has its own figure here, because the units are measuring different things and only the density links them.
Put next to water — 1 g per mL exactly — self-rising flour measures 0.52834 g per mL. That ratio, 52.83%, is what separates this page from every other ingredient in the same units, and it is measured rather than defined.
A level tablespoon of self-rising flour is 7.812 g, which puts a teaspoon at 2.604 g and a tablespoon and a half — the quantity recipes are fondest of — at 11.72 g. Levelling twice is where the error comes from, so the scale is the faster instrument once the quantity passes a couple of spoons.
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
grams- The amount of self-rising flour you are converting, in grams
0.128- Tablespoons per gram for self-rising flour, from its density of 0.52834 g/mL
tablespoons- The equivalent quantity in tablespoons
How it works, step by step
- Enter the quantity in grams.
- It is multiplied by 0.128, the tablespoons-per-gram figure for self-rising flour.
- The result appears in tablespoons, 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 tablespoons
Take 50 g of self-rising flour: 50 × 0.128 gives 6.4 tablespoons. Doubling the batch takes it to 12.8 tablespoons, because the relationship is a straight proportion once the density is known.
150 g of self-rising flour in tablespoons
Take 150 g of self-rising flour: 150 × 0.128 gives 19.2 tablespoons. Doubling the batch takes it to 38.4 tablespoons, because the relationship is a straight proportion once the density is known.
500 g of self-rising flour in tablespoons
Take 500 g of self-rising flour: 500 × 0.128 gives 64 tablespoons. Doubling the batch takes it to 128 tablespoons, because the relationship is a straight proportion once the density is known.

Frequently asked questions
How many tablespoons are in 1 g of self-rising flour?
One gram of self-rising flour is 0.128 tablespoons. Half that quantity is 0.064 tablespoons and double it is 0.256 tablespoons, 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 tablespoon of self-rising flour is 7.812 g, and a scale reading to the nearest gram is working at 12.8% 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 3 tbsp of self-rising flour weigh?
3 tbsp of self-rising flour comes to 23.438 g, or 23.438 grams. This page runs that calculation in reverse — enter a weight and it returns the volume — and the tablespoons-to-grams page does it in the direction the question is usually asked.
