100 Grams of Rice to Cups
½ cup in a US cup — and what that looks like with a measuring spoon
100 grams of uncooked white rice is ½ cup in a US cup. In the kitchen that is ½ cup plus 2 teaspoons.
Grams weigh and cups fill, so the answer only exists once you say what is in the cup. A US cup of uncooked white rice weighs 185 g, and every figure on this page comes from that one number.
It also depends on whose cup you mean, though not much at this weight. A 250 ml metric cup — the standard in the UK, Australia, New Zealand and Canada — holds about 5.7% more than the 236.6 ml US cup, but 100 g of uncooked white rice still rounds to ½ cup in both: 0.54 US cups against 0.51 metric.
Round to the nearest measure in a standard cup set — ½ cup — and you are 7 g under, about 7% of the amount.
100 g of rice in each cup standard
| Cup standard | Size | Grams per cup | Cups |
|---|---|---|---|
| US customary | 236.6 ml | 185 g | ½ |
| Metric (UK, AU, NZ, CA) | 250 ml | 195 g | ½ |
| Imperial (older UK) | 284 ml | 222 g | ½ |
A recipe that says "cups" without saying which one is almost always American. At 100 g it barely matters for uncooked white rice — both cups round to the same measure — but on a larger batch the 5.7% gap compounds.
How to measure 100 g of rice without scales
This is dry, uncooked long-grain white rice, poured into the cup and levelled. Do not press it down.
Rice roughly triples in volume as it cooks, so this figure is for the dry grain. Cooked rice is about 186 g per cup — nearly the same weight, but a very different amount of food.
- Build it as ½ cup plus 2 teaspoons rather than guessing at ½ of a cup.
- 100 g is 8.65 tablespoons of uncooked white rice, at 11.56 g per tablespoon.
- A digital scale removes the question entirely, and costs less than the ingredients it saves.

Frequently asked questions
How many cups is 100 grams of rice?
100 grams of uncooked white rice is ½ cup in a US cup, based on 185 g per cup. A 250 ml metric cup rounds to the same ½ cup.
What is the easiest way to measure 100 g of rice?
½ cup plus 2 teaspoons — built from a standard cup and spoon set. This is dry, uncooked long-grain white rice, poured into the cup and levelled. Do not press it down.
Is 100 g of rice the same in cups in the UK?
Near enough. A UK, Australian, New Zealand or Canadian metric cup is 250 ml against the US cup's 236.6 ml, so the exact answers differ — 0.54 US cups against 0.51 metric — but both round to ½ cup, and at this weight you can use either.
Can I just use ½ cup instead?
½ cup of uncooked white rice weighs about 93 g, so you would be 7 g under. For a sauce or a soup that is fine; for a cake, where the flour-to-liquid ratio sets the crumb, weigh it.
How many ounces is 100 grams?
100 grams is 3.53 ounces by weight. Unlike cups, that answer is the same whatever you are measuring — ounces weigh, fluid ounces fill, and they are not the same unit.
