Dry to Cooked Grain Conversions (Because Every Grain Is Different)

Cook a cup of dry rice and you don't get a cup of cooked rice — you get nearly three. Get that math wrong and you're either feeding four people portions for two, or eating leftovers all week.

Fast Answer

Most grains end up two to three times their dry volume once cooked, but the range is wide enough that "about double" isn't good enough — find your specific grain in the chart below.

Find Your Grain's Ratio

That’s the short version. The long version is that every grain absorbs liquid differently — quinoa fluffs up more easily than rice, bulgur swells quickly, couscous barely cooks at all.

The chart below covers water ratios, cook times, and yields for all 32, plus a calculator that does the math for whatever amount you’re working with.

Quinoa

1 cup dry quinoa + 2 cups liquid → about 3 cups cooked.

Quinoa cooks faster than rice (15–20 minutes) and fluffs up lighter — when it’s done, you’ll see the germ pull away into a small white spiral around each seed. Rinse it first unless the package says pre-rinsed; the natural coating is bitter and rinsing makes a real difference here, unlike with rice.

Red and black quinoa take a few extra minutes and stay firmer than white or golden — yields are close, but not identical.

 

Rice — White vs. Brown

White rice: 1 cup dry + 2 cups water → about 3 cups cooked. Brown rice: 1 cup dry + 2¼–2½ cups water → about 3–4 cups cooked, but takes roughly twice as long.

This is the substitution people get wrong most often. Brown rice isn’t just “rice that takes longer” — it needs more water per cup and a longer simmer (about 45 minutes vs. 18–20 for white), or the bran layer never fully softens. Swap one for the other 1:1 on water and you’ll end up with crunchy brown rice or soggy white rice.

If you’re working with rice specifically and want pasta comparisons too, the pasta and rice conversions page covers that in more depth.

 

Bulgur

1 cup dry bulgur + 2 cups water → about 3 cups cooked.

Bulgur is parboiled, cracked wheat, so it cooks faster than whole wheat berries — usually 12–15 minutes of simmering, or even just a soak in hot water off the heat for fine bulgur (the way tabbouleh is traditionally made). It stays slightly chewy even when fully done. That’s the texture, not a sign it needs more time.

A reader once wrote in needing exactly 2 cups cooked for a recipe and not wanting a leftover portion sitting around. Working backward from the 1:2:3 ratio: about ¾ cup dry bulgur with 1½ cups water gets you close to 2 cups cooked.

 

Couscous

1 cup dry couscous + 1–1¼ cups boiling liquid, off heat 5 minutes → about 2 cups cooked.

Regular (Moroccan) couscous isn’t cooked the way grains are — it’s rehydrated. Pour boiling liquid over it, cover, let it sit, then fluff with a fork. No simmering involved.

Israeli (pearl) couscous is a different product — it’s a small pasta, not a grain, and it’s boiled rather than steamed. A reader asked whether pearl couscous yields the same as regular couscous; based on what I could find, pearl comes out a bit different per dry cup than Moroccan — though I haven’t tested both side by side to confirm it myself. If you have, I’d genuinely like to know what you found.

 

Barley

1 cup dry pearled barley + 3 cups liquid → about 3½–4 cups cooked.

Most grocery store barley is pearled — the outer hull and most of the bran polished off, which is why it cooks in about 45 minutes instead of well over an hour. If your bag says “hulled” or “hull-free,” you’re working with a different product that holds onto more bran and takes noticeably longer.

A reader once asked about scaling this down for ¼ cup of dry barley — the math holds at any size, just keep the liquid at three times whatever dry amount you’re using.

 

Farro

1 cup dry farro + 2½ cups water → about 3 cups cooked.

Semi-pearled farro (the kind most stores sell) simmers in about 25–30 minutes. Whole farro — sold as “whole grain” or “farro integrale” — takes significantly longer and benefits from an overnight soak. Either way, farro stays chewy even when fully cooked. That’s the point of the grain, not a sign it needs more time.

Frequently Asked Questions

Why does quinoa yield differently from rice?
Quinoa has a lighter structure than rice and absorbs liquid faster, which is why it ends up fluffier and slightly higher in volume per dry cup.

Is weight a better measurement than volume for grain conversions?
Weight is more precise, especially for dry grains — one dry cup works out to roughly 6.8 ounces, or about 193 grams, though this varies slightly by grain. Volume measurements work fine as long as you’re consistent about which cup you’re using.

Does my rice cooker’s measuring cup match a standard cup?
No. Rice cookers typically come with their own smaller cup, not a standard US measuring cup. If you’re using the chart above with a rice cooker cup, the ratios will be off — measure with a regular cup instead, or adjust accordingly.

Can I substitute one grain for another using the same ratio?
Not reliably. Even grains that look similar — barley and farro, for instance — absorb different amounts of liquid and cook on different timelines. Use the individual sections above rather than assuming a 1:1 swap.

Does rinsing grains change the final yield?
Rinsing removes surface starch and residue, which affects texture and clumping more than overall volume. The yield numbers above hold whether you rinse or not.

Why do my grains turn mushy?
Usually too much liquid, too much time, or both. Once a grain bursts and releases its starch, there’s no fixing the texture — only working it into something like a porridge or a binder for another dish.

Can I freeze cooked grains without losing volume?
Freezing itself doesn’t change the volume much. What changes is texture on reheating, if moisture isn’t managed — grains can dry out or turn gummy depending on how they’re stored and reheated.

Are ancient grains harder to convert than modern grains?
Not harder, just different. Farro, spelt, kamut, and similar grains tend to absorb more liquid and take longer to cook than more processed modern grains, which is exactly why they get their own entries in the chart.

    Hello thanks for the information, just a question tho, when you say liquid are you still referring to water? As in water to cook the bulgur. I need to be clear on this.Thank you

    1. Danny, the reason I say liquid and not water is because besides water, some people like to use chicken, beef or vegetarian stock while others use a combination 50/50 juice/water combination. It really depends on your personal preferences.

    What Is the Dry To Cooked Grain Yield
    I love this chart! just what I was looking for. We have recently retired and now I trying to create a collection of healthy recipes to become my repeatable menu for my us. I hope to find more info as I peruse your blog.
    Thanks

    Very useful table I use grains quite a lot but to remember each ratio and yield not easy. Just used your chart to make a barley, mushroom and vegetable ‘risotto’ Lovely cold day lunch. Thank you I think I’ll frame this and hang in my kitchen.

  4. How is it possible that I look up “raw to cooked grits ratio” and come up with a site that doesn’t say “grits” anywhere in it? Why is this so difficult to find online?

  5. I was disappointed not to find these grains included:

    Oat Groats (unprocessed whole-grain oats)
    Kamut (you do include Spelt—why not Kamut/Khorasan?)
    Rye

    I assume the Barley you list is Hulled Barley (unprocessed whole grain) and not Pearled Barley or Pot Barley, but it would be really nice if you were explicit.

    I’m pleased that you include things like Amaranth, Buckwheat, Chia, and Quinoa, but since none of these is a grain, perhaps you should change the title to be something like “Grains and Seeds.”

    Your chart is a godsend, thank you thank you! Working with a scientific, gram-gy-gram doctor I need to know if whole grains’ yield holds for cracked or cereal whole grain as well!

    Well, aren’t you a wonderful person? Yes, indeed! We just got a Zojirushi rice cooker and Instant Pot Zest rice/grain cooker. I ordered a cookbook for each machine and have watched too many videos about grains! No one provided as much info as you…and that includes the cookbooks! Thank you. When you see happy people holding hands and enjoying their healthy life, know that you could be the reason why!

    Thank you so much! It’s so aggravating that on the label of every wheat, grain & pasta the weight says “dry”. Like I’m going to cook just a ¼ cup of it. I’m on a diet and I need to know how many calories are in my food, but who knew until now. We would guess double but I was always nervous about it because of the high calories in some of them. Now we know. Sigh of relief!

    Again, thank you very much!

  9. Can these grains be cooked in a rice cooker? Especially wondering about Farro (my new favorite) and barley.

  10. Can you tell me how much liquid in bulgar to equal 2 cups of cooked, all info I have found online is for 3 cups and it seems like I end up wasting some. Thanks!

    1. Hi Brenda, not exact but to get to 2 cups, it’s about 70% of each so .7 cups of rice and 1.4 cups of water should yield around 2 cups of Bulgar rice. If it were me, I would make the 3 cups of rice, use 2 cups for the recipe and save the other cup for lunch or better yet, a nice breakfast bowl with a poached egg on top.

  11. This is wonderful. Any idea what the conversions are for grams? Or water used if cooking in an instant pot?

  12. Hi, I just found this list, thank you.I have a couple of questions:
    Do you happen to know how many grams (or ounces) are in the 1 cup measurements. I have found that there can be some differences depending on which measuring cup I use so I prefer to be more exact and use a food scale.

    Also, when you indicate 1 cup, especially for the rice, is that a regular dry measure cup or is it a “rice measuring 1 cup” which is actually considerably smaller than a regular cup. I have both a rice cooker and a pressure cooker-type and both refer to the “special cup used for rice measurements”.

    Thanks, I look forward to hearing back from you

    1. Sue, great questions. One dry cup is equal to 6.8 US dry ounces or 192.777 grams. I believe this is why rice cookers come with their own measuring cups because they figure people will use their liquid measuring cups. I do this all the time and know it is not accurate, but I find it doesn’t matter that much. Now baking is another story, and you have to be accurate, but cooking rice not as much.

  13. Well, like all the other commenters have said, this is amazing!! And thank you for accommodating all of the questions and tweaks!! ?

    1. Hi Rachel, I have not heard of “fine” couscous, but I assume you are speaking of Moroccan couscous. And your reference to “pearl” couscous is Lebanese Pearl, which is roughly the size of a pea and larger than Israeli couscous. Now to their yields. I found online that 1 cup of Pearl couscous yields 3 cups cooked or one cup less than Moroccan. I can’t guarantee this is correct without actually cooking both. If you make some Lebanese Pearl couscous, please send me your yield. Thanks
