To convert grams of rice flour into millilitres, multiply by 1.4973939: one gram comes to 1.4973939 millilitres. 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 — 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.
Rice flour has a density of 0.66783 g per mL, so 100 mL of it weighs 66.78 g and 250 mL weighs 167 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 66.78% 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 0.633% 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
1.4973939019- Millilitres per gram for rice flour, from its density of 0.66783 g/mL
millilitres- The equivalent quantity in millilitres
How it works, step by step
- Enter the quantity in grams.
- It is multiplied by 1.4973939019, the millilitres-per-gram figure for rice 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 rice flour in millilitres
Take 50 g of rice flour: 50 × 1.4973939 gives 74.8697 millilitres. Doubling the batch takes it to 149.739 millilitres, because the relationship is a straight proportion once the density is known.
150 g of rice flour in millilitres
150 g of rice flour weighs out at 224.609 millilitres. Divide 224.609 by 1.4973939 and you get back to 150 g, which is the quickest check that the factor is the right way up.
500 g of rice flour in millilitres
500 g of rice flour weighs out at 748.697 millilitres. Divide 748.697 by 1.4973939 and you get back to 500 g, which is the quickest check that the factor is the right way up.

Frequently asked questions
How many millilitres are in 1 g of rice flour?
One gram of rice flour is 1.4973939 millilitres. Half that quantity is 0.748697 millilitres and double it is 2.99479 millilitres, 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 millilitre of rice flour is 0.6678 g, and a scale reading to the nearest gram is working at 150% 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 rice flour weigh?
15 mL of rice flour comes to 10.017 g, or 10.017 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.
