Rice Cooker Cups Explained: Uncooked vs Cooked

Here is the most confusing number in small appliances: two rice cookers can both say “10 cups” on the box and be different-sized pots. That’s because “cup” means two different things depending on where the brand comes from — and most boxes never tell you which one they’re using.
The two scales
Uncooked cups (the Japanese scale). Zojirushi and other Japanese brands rate capacity by the measuring cup that ships with the cooker: about 180 ml, filled with dry, uncooked rice. A “5.5-cup” Zojirushi takes 5.5 of those measures of dry rice. Note that 180 ml is smaller than a US measuring cup (about 240 ml), so even the cup itself isn’t the cup in your drawer.
Cooked cups (the US shelf scale). Aroma and many US-market brands rate capacity by the volume of finished, cooked rice. A “6-cup” cooker on this scale makes 6 cups of cooked rice — which starts from substantially less dry rice than a 6-cup uncooked rating.
Rice expands as it cooks. How much do the scales differ? We never convert between them for brands that don’t publish both numbers — but one model in our verified catalog does publish both, and it’s the perfect Rosetta stone.
The same pot, wearing both numbers
The Cuckoo CR-1095 is rated 10 cups uncooked / 20 cups cooked — both figures printed by the manufacturer. Read that again: on the uncooked scale it’s a “10-cup” cooker; on the cooked scale the identical pot is a “20-cup” cooker. So when a US-style box advertises “10 cups” on the cooked basis, it’s roughly the class of pot a Japanese brand would call 5 cups. The “10-cup” cooker that sounds family-sized can be a mid-size pot in disguise.
Our verified models, exactly as each brand states them
We print each capacity exactly as the brand publishes it and never fill in the missing side:
| Model | Capacity, as the brand states it | Wattage | Price (read Oct 7, 2026) |
|---|---|---|---|
| Zojirushi Neuro Fuzzy (NS-ZCC10) | 5.5 cups uncooked (~180 ml cup) / 1.0 L — cooked figure not published | 680 W | $279.99 at Zojirushi Online Store |
| Zojirushi Micom (NL-BAC05) | 3 cups uncooked / 0.54 L — cooked figure not published | 500 W | $179.99 at Zojirushi Online Store |
| Cuckoo (CR-1095) | 10 cups uncooked / 20 cups cooked — both published | 700 W | $99.99 at CUCKOO America |
| Aroma (ARC-763C) | 6 cups cooked / 1.5 Qt — uncooked figure not published | 300 W | $30 at Aroma (aromaco.com) |
Two lessons from that table. First, the Aroma’s “6 cups” and the Zojirushi’s “5.5 cups” look like neighbours and aren’t: one is cooked, one is uncooked, so the Zojirushi is the much bigger pot. Second, Zojirushi doesn’t publish cooked equivalents and Aroma doesn’t publish an uncooked figure — anyone who shows you a converted number for those models made it up, and so would we.

How to size a cooker for your household
Start from servings, then match the scale:
| Household | Shop this rating | Verified example | Why it fits |
|---|---|---|---|
| 1–2 people | ~3 cups uncooked | Zojirushi NL-BAC05 ($179.99, Zojirushi Online Store, Oct 7 2026) | A true small Micom cooker; a family of four will outgrow it |
| First cooker / dorm / tight budget | Cooked-cup rated, small | Aroma ARC-763C, 6 cups cooked ($30, Aroma, Oct 7 2026) | The lowest verified price we’ve seen in this category — just read “6 cups” as cooked |
| 3–5 people, rice most days | ~5.5 cups uncooked | Zojirushi NS-ZCC10 ($279.99, Zojirushi Online Store, Oct 7 2026) | The size class most Japanese lineups are anchored on |
| 6+ people / meal prep | 10 cups uncooked (20 cooked) | Cuckoo CR-1095 ($99.99, CUCKOO America, Oct 7 2026) | Both bases published, so there’s no scale guessing at all |
And the trap to avoid: never compare a cooked-cup number against an uncooked-cup number as if they were the same axis. If a listing won’t say which basis it uses, that’s a reason to walk away from the listing, not to guess.
The short version
Japanese brands count dry-rice measures of about 180 ml; US brands usually count finished cooked rice; and the one verified model that prints both shows the cooked number running about double. A “10-cup” cooker can be a feast pot or a weeknight pot depending on which language the box is speaking. Check the basis first, then the size — in that order, and you’ll never buy the wrong pot.
