One gram of uncooked brown rice is 1.2452012 millilitres, so converting grams of uncooked brown rice to millilitres means multiplying by 1.2452012. 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 — uncooked brown rice measures 0.80308 g per mL. That ratio, 80.31%, is what separates this page from every other ingredient in the same units, and it is measured rather than defined.
Uncooked brown rice has a density of 0.80308 g per mL, so 100 mL of it weighs 80.31 g and 250 mL weighs 200.8 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 80.31% 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 0.526% of a cup of uncooked brown rice, so weighing gets an accuracy no measuring cup can reach. A 500 g pack of it is 2.632 cups, and a 1 kg pack 5.263.
The condition this weight assumes: The bran layer left on the grain makes it slightly heavier per cup than white rice of the same variety.
The formula
grams- The amount of uncooked brown rice you are converting, in grams
1.24520124474- Millilitres per gram for uncooked brown rice, from its density of 0.80308 g/mL
millilitres- The equivalent quantity in millilitres
How it works, step by step
- Enter the quantity in grams.
- It is multiplied by 1.24520124474, the millilitres-per-gram figure for uncooked brown rice.
- 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 uncooked brown rice in millilitres
A recipe calling for 50 g of uncooked brown rice needs 62.2601 millilitres on the scale. The arithmetic is 50 × 1.2452012 = 62.260062, and halving the recipe halves the weight to 31.13 millilitres.
150 g of uncooked brown rice in millilitres
150 g of uncooked brown rice weighs out at 186.78 millilitres. Divide 186.78 by 1.2452012 and you get back to 150 g, which is the quickest check that the factor is the right way up.
500 g of uncooked brown rice in millilitres
500 g of uncooked brown rice weighs out at 622.601 millilitres. Divide 622.601 by 1.2452012 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 uncooked brown rice?
One gram of uncooked brown rice is 1.2452012 millilitres. Half that quantity is 0.622601 millilitres and double it is 2.4904 millilitres, so the figure scales straight up and down — there is no offset in this conversion, only the factor.
Why is a cup of uncooked brown rice not 236 g like water?
Because weight per cup depends on what is in the cup. Uncooked brown rice has a density of 0.80308 g per mL where water has 1.00, so a cup of it weighs 190 g rather than 236.6 g. That is a difference of 46.6 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 uncooked brown rice by roughly 20% — about 19 g either side of 190 g — because the bran layer left on the grain makes it slightly heavier per cup than white rice of the same variety. Weighing removes the question entirely.
Is a fluid ounce of uncooked brown rice 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 uncooked brown rice weighs 0.8378 oz, so the two readings differ by 16.2%. 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 uncooked brown rice would weigh 200.77 g instead of 190 g — 10.8 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 uncooked brown rice is 0.8031 g, and a scale reading to the nearest gram is working at 125% 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 uncooked brown rice weigh?
15 mL of uncooked brown rice comes to 12.046 g, or 12.046 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.
