Rice Calculator
What Is the Rice Calculator?
The rice calculator answers the practical dinner question: how much rice do I cook? Enter how many people you are feeding and whether rice is the main event or a side dish, and the calculator returns the uncooked rice needed in cups, grams, or rice cooker cups, along with the cooked yield you can expect.
Rice roughly doubles or slightly more in volume and weight as it cooks, which is the detail that makes eyeballing unreliable. Half a cup of dry rice looks modest in the pot but becomes a full cup and a half on the plate.
How Much Rice per Person?
When rice is the primary dish, plan on about half a US cup of uncooked rice per person, which is around 90 to 100 grams dry and roughly doubles to 200 grams cooked after absorbing water. Increase that to a full cup if you are feeding large or very hungry adults, teenagers, or athletes.
As a side dish next to curry or stir fry, a quarter cup of uncooked rice per person does the job, about 45 to 50 grams. For reference, a standard rice cooker cup measures 180 milliliters, which is a bit smaller than the 240 milliliter US legal cup, and at a 2 to 3 rice cooker cup scale for groups this distinction matters.
Uncooked to Cooked Rice Conversion
One cup of dry white rice yields approximately 2 to 3 cups cooked depending on variety and cooking method, with 1 to 2 being the safe planning baseline for most long grain types. In weight, 180 grams uncooked becomes about 360 to 400 grams cooked. Absorption varies: sticky short grain rice takes up less water, while brown rice holds more and stays denser.
The calculator applies sensible per serving amounts to your party size automatically, and it also runs in reverse if you know how much dry rice is left in the bag and want to know how many plates it covers.
Sample Calculations for Groups
Cooking dinner for four as the main dish needs about 2 cups, or 360 to 400 grams, of uncooked rice. A family of six needs 3 cups or roughly 540 grams. A potluck side for eight people runs about 2 cups uncooked since portions shrink when dishes compete.
Leftover cooked rice keeps 3 to 4 days refrigerated and freezes well, so erring one serving high is rarely a mistake. Rice portioning matters most for events and meal prep, where the calculator saves both money and waste.
Frequently Asked Questions
How much uncooked rice do I need per person?
About half a US cup, or 90 to 100 grams, when rice is the main dish, and roughly a quarter cup, or 45 to 50 grams, when it is a side. Cooked, the main dish portion is around 200 grams per person.
How much does rice expand when cooked?
One cup of dry rice becomes about 2 to 3 cups cooked, and the weight roughly doubles. Short grain and sticky rice expand slightly less than long grain varieties.
What is a rice cooker cup?
Rice cooker cups hold 180 milliliters, smaller than the 240 milliliter US legal cup. If a cookbook or cooker scale uses rice cooker cups, 1 rice cooker cup uncooked feeds about one and a half people as a side.
How many people does 1 kg of rice feed?
At 90 to 100 grams dry per serving as a main dish, 1 kilogram feeds 10 to 11 people, or around 20 people if rice is served as a side.
How long does cooked rice keep?
Cooked rice keeps 3 to 4 days in the refrigerator when cooled quickly and stored covered, and freezes well for up to a couple of months. Reheat until steaming hot throughout.
