Grams of self-rising flour to teaspoons runs on one number, 0.384 teaspoons 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.
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.
A level teaspoon of self-rising flour weighs 2.604 g. A kitchen scale that reads to the nearest gram is therefore working at roughly 38.4% resolution on a single spoonful, which is why measuring spoons beat scales below about 5 g and lose to them above it. Three teaspoons make a tablespoon, so the same spoonful is 7.813 g if the recipe scales up.
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
0.384- Teaspoons per gram for self-rising flour, from its density of 0.52834 g/mL
teaspoons- The equivalent quantity in teaspoons
How it works, step by step
- Enter the quantity in grams.
- It is multiplied by 0.384, the teaspoons-per-gram figure for self-rising flour.
- The result appears in teaspoons, with a second reading in mL 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 teaspoons
A recipe calling for 50 g of self-rising flour needs 19.2 teaspoons on the scale. The arithmetic is 50 × 0.384 = 19.2, and halving the recipe halves the weight to 9.6 teaspoons.
150 g of self-rising flour in teaspoons
150 g of self-rising flour weighs out at 57.6 teaspoons. Divide 57.6 by 0.384 and you get back to 150 g, which is the quickest check that the factor is the right way up.
500 g of self-rising flour in teaspoons
Take 500 g of self-rising flour: 500 × 0.384 gives 192 teaspoons. Doubling the batch takes it to 384 teaspoons, because the relationship is a straight proportion once the density is known.

Frequently asked questions
How many teaspoons are in 1 g of self-rising flour?
One gram of self-rising flour is 0.384 teaspoons. Half that quantity is 0.192 teaspoons and double it is 0.768 teaspoons, 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 teaspoon of self-rising flour is 2.604 g, and a scale reading to the nearest gram is working at 38.4% 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 2 tsp of self-rising flour weigh?
2 tsp of self-rising flour comes to 5.2083 g, or 5.2083 grams. This page runs that calculation in reverse — enter a weight and it returns the volume — and the teaspoons-to-grams page does it in the direction the question is usually asked.
