To convert millilitres of rice flour into grams, multiply by 0.66782695: one millilitre comes to 0.66782695 grams. 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
millilitres- The amount of rice flour you are converting, in millilitres
0.667826948361- Grams per millilitre for rice flour, from its density of 0.66783 g/mL
grams- The equivalent quantity in grams
How it works, step by step
- Enter the quantity in millilitres.
- It is multiplied by 0.667826948361, the grams-per-millilitre figure for rice 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 rice flour in grams
Take 15 mL of rice flour: 15 × 0.66782695 gives 10.0174 grams. Doubling the batch takes it to 20.0348 grams, because the relationship is a straight proportion once the density is known.
100 mL of rice flour in grams
Take 100 mL of rice flour: 100 × 0.66782695 gives 66.7827 grams. Doubling the batch takes it to 133.565 grams, because the relationship is a straight proportion once the density is known.
250 mL of rice flour in grams
Take 250 mL of rice flour: 250 × 0.66782695 gives 166.957 grams. Doubling the batch takes it to 333.913 grams, because the relationship is a straight proportion once the density is known.

Frequently asked questions
How many grams are in 1 mL of rice flour?
One millilitre of rice flour is 0.66782695 grams. Half that quantity is 0.333913 grams and double it is 1.33565 grams, 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 many millilitres of rice flour is 500 g?
500 g of rice flour is 748.7 millilitres — 1.49739 millilitres to one gram, so 500 × 1.49739 = 748.7. Going that way is a division by 0.667827, or a multiplication by 1.49739 if you prefer.
