450 Grams of White Rice in Cups
450 grams of white rice doesn't land on a clean fraction, so the result below is calculated exactly rather than rounded to a common measure. Based on a density of 185g per cup, it equals 2.43 cups.

450 grams of white rice = 2.43 cups (2⅜ cups / 38.9 tbsp / 116.8 tsp)
White Rice has a density of approximately 185g per cup. Uncooked, long grain. Short grain runs closer to 190g per cup. Source: USDA FoodData Central. This is the figure used everywhere on this page, including the tablespoon and teaspoon values, so the numbers stay consistent whether you're reading the summary line, the table, or the FAQ answers below.
| Grams | Cups | Fraction | Tablespoons | Teaspoons |
|---|---|---|---|---|
| 400g | 2.16 | 2⅛ | 34.6 | 103.8 |
| 425g | 2.30 | 2⅓ | 36.8 | 110.3 |
| 450g | 2.43 | 2⅜ | 38.9 | 116.8 |
| 475g | 2.57 | 2⅝ | 41.1 | 123.2 |
| 500g | 2.70 | 2⅔ | 43.2 | 129.7 |
How 450g Converts, Step by Step
450g divided by 185g (the weight of one cup of white rice) equals 2.43 cups. Multiplying that by 16 gives 38.9 tablespoons, and by 48 gives 116.8 teaspoons, since one cup always equals 16 tablespoons or 48 teaspoons regardless of the ingredient.
White Rice is lighter than water, which weighs about 236g per cup. That's why 450g of white rice takes up more volume (575ml) than the same weight of water would (451ml). For a side-by-side look at how other ingredients compare, see the 450 grams to cups page.
If You're Using a Metric or Imperial Cup
The 2.43 cup figure above uses the US Customary cup (236.588ml). Recipes written outside the US sometimes use a metric cup (250ml) or an imperial (uk) cup (284.131ml) instead. At 450g, that's 2⅓ metric cups or 2⅛ imperial cups of white rice, close to the US figure but not identical. The cup standard switch in the converter above recalculates this instantly for any gram amount.
Scaling This 450g Amount
Doubling a recipe that calls for 450g of white rice means weighing 900g, or measuring 4.86 cups if you're working by volume instead of weight. Halving it means 225g, or 1.22 cups. Weight scales exactly with simple multiplication; cup measurements compound any scooping error each time they're doubled or halved, so weighing is more reliable the more a recipe is scaled.
White Rice Next to Other Grains & Pasta
Within grains & pasta, density still varies by ingredient. At 450g, quinoa (170g per cup) measures 2⅔ cups, compared to 2⅜ cups for white rice. Swapping ingredients in a recipe by cup measurement alone, without adjusting for this difference, changes the actual weight used.
Where This Amount Shows Up in Recipes
- A single serving of rice is typically 65g to 90g uncooked.
- Rice pudding recipes often call for 100g to 150g.
- Fried rice for four people usually needs about 300g uncooked.
Measuring This Precisely
Grains & Pasta
Spoon into the cup and level off. Avoid pressing down, since grains and pasta shapes settle differently than powders.
For exact results
Rice and grains can vary in density based on how long they've been stored, since older, drier grains pack slightly more densely into the same cup than fresher ones.

Frequently Asked Questions
What is 450 grams of white rice in cups exactly?+
450 grams of white rice equals 2.43 cups, based on a density of 185g per cup.
Why doesn't 450g of white rice match a simple fraction?+
450g isn't a multiple of white rice's per-cup weight, so the cup value lands between common fractions. The closest practical measure is 2⅜ cups.
What's the most reliable way to measure 450g of white rice?+
A kitchen scale set to grams gives an exact 450g reading. Cups only approximate this amount, since 2⅜ cups rounds to the nearest practical fraction.
Is 450g likely a typo for a rounder amount?+
Possibly, if a recipe seems to expect a cleaner number. Check the nearby amounts table below for the closest common gram values for white rice.
