One gram of rice flour is 0.30379747 teaspoons, so converting grams of rice flour to teaspoons means multiplying by 0.30379747. That factor is specific to this ingredient — it comes from its density, not from any relationship between the two units.
Put next to water — 1 g per mL exactly — rice flour measures 0.66783 g per mL. That ratio, 66.78%, is what separates this page from every other ingredient in the same units, and it is measured rather than defined.
A level teaspoon of rice flour weighs 3.292 g. A kitchen scale that reads to the nearest gram is therefore working at roughly 30.4% 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 9.875 g if the recipe scales up.
Grams are the unit this conversion is really for. A domestic scale resolves to a gram, which is 0.633% of a cup of rice flour, so weighing gets an accuracy no measuring cup can reach. A 500 g pack of it is 3.165 cups, and a 1 kg pack 6.329.
How the figure is arrived at: Fine, dense and gluten-free. Common in gluten-free blends and in tempura and rice-noodle batters.
The formula
grams- The amount of rice flour you are converting, in grams
0.303797468354- Teaspoons per gram for rice flour, from its density of 0.66783 g/mL
teaspoons- The equivalent quantity in teaspoons
How it works, step by step
- Enter the quantity in grams.
- It is multiplied by 0.303797468354, the teaspoons-per-gram figure for rice 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 rice flour in teaspoons
50 g of rice flour weighs out at 15.1899 teaspoons. Divide 15.1899 by 0.30379747 and you get back to 50 g, which is the quickest check that the factor is the right way up.
150 g of rice flour in teaspoons
Take 150 g of rice flour: 150 × 0.30379747 gives 45.5696 teaspoons. Doubling the batch takes it to 91.1392 teaspoons, because the relationship is a straight proportion once the density is known.
500 g of rice flour in teaspoons
A recipe calling for 500 g of rice flour needs 151.899 teaspoons on the scale. The arithmetic is 500 × 0.30379747 = 151.89873, and halving the recipe halves the weight to 75.9494 teaspoons.

Frequently asked questions
How many teaspoons are in 1 g of rice flour?
One gram of rice flour is 0.30379747 teaspoons. Half that quantity is 0.151899 teaspoons and double it is 0.607595 teaspoons, so the figure scales straight up and down — there is no offset in this conversion, only the factor.
Why is a cup of rice flour not 236 g like water?
Because weight per cup depends on what is in the cup. Rice flour has a density of 0.66783 g per mL where water has 1.00, so a cup of it weighs 158 g rather than 236.6 g. That is a difference of 78.6 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 rice flour by roughly 20% — about 15.8 g either side of 158 g — because fine, dense and gluten-free. Weighing removes the question entirely.
Is a fluid ounce of rice 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 rice flour weighs 0.6967 oz, so the two readings differ by 30.3%. 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 rice flour would weigh 166.96 g instead of 158 g — 8.96 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 rice flour is 3.292 g, and a scale reading to the nearest gram is working at 30.4% 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 rice flour weigh?
2 tsp of rice flour comes to 6.5833 g, or 6.5833 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.
