Your measuring cup is in the dishwasher. The rental kitchen doesn't have one. You're at a cabin and the drawer holds one spatula and a bottle opener. Rice portions don't need to fall apart because of it — every tool below is already in your kitchen, and every one maps back to the same 90 g / 45 g portions this site uses everywhere.
The tablespoon method: 8 spoons for 90 g, 4 spoons for 45 g
A level tablespoon holds 15 ml. A US measuring cup holds 240 ml — that's 16 level tablespoons in one cup. A full cup of raw white rice weighs about 180 g, so a single level tablespoon comes to roughly 11 g.
- 90 g (main course) = 8 level tablespoons
- 45 g (side dish) = 4 level tablespoons
"Level" is the entire trick. A heaped spoon carries noticeably more rice — the same spoon that should give you 90 g can quietly deliver 120 g. Scoop, then scrape the spoon flat across the bag or a knife edge, and only then count it.
The teaspoon method: when a tablespoon feels too big
A teaspoon holds 5 ml — a third of a tablespoon. Since one tablespoon of rice is about 11 g, one teaspoon comes to roughly 3.75 g.
- 90 g = 24 teaspoons
- 45 g = 12 teaspoons
Teaspoons earn their keep for kid portions, for the single serving added to a small pot, or any time 8 big scoops feel clunky. Twenty-four spoons is a slow count, but it is an exact one.
The palm: a fast estimate, with the honesty attached
A cupped palm holds about one side-dish portion of dry rice. That is your 45 g ballpark, right in your hand.
The palm is the fast lane, not the accuracy lane. The same cupped palm reads differently from hand to hand, so treat it as "about a side portion", not a weight. If the portion matters — a scaled recipe, a calorie count, a meal plan — use the tablespoons. If "about right" is good enough, the palm gets you there. (For reference, site numbers come from the spoon math above: 4 level tablespoons ≈ 45 g.)
Why the "finger method" is not this page
Check any search results for "measuring rice without a measuring cup" and the top results lean on the finger method: pour rice into the pot, add water up to the first knuckle. We checked the current top results — pages from tidewatergrain.com, 177milkstreet.com, and foodabovegold.com all lead with a finger or knuckle technique. It is a fine water technique — but it measures water, not rice. If you need a specific weight of dry grain, the knuckle line cannot tell 90 g from 60 g. It also needs a pot or a rice cooker standing by, which is exactly the situation this page is built for: dry rice, no cup, no scale, portion still right.
One number, held across the whole site
Every portion above uses the US food-label cup: 240 ml. If the only "cup" you own came with a rice cooker, know that those cups hold 180 ml — about 150 g of rice — so they run about a quarter short of the portions above. When you see "1 cup" on this site, it means 240 ml, and 8 tablespoons is that cup's worth of rice, measured one spoon at a time.
FAQ
No tablespoons either? A cupped palm is roughly one side portion, and two palm-fulls get you close to a main portion. It is the least precise option on this page — expect a real swing either way, then adjust the next time you cook. (Site numbers come from the spoon math: 4 level tablespoons ≈ 45 g, 8 ≈ 90 g.)
Does rinsing change the weight? Rinsing coats the grains with water and the drained weight drifts up a few grams. Measure dry, then rinse — that keeps the 90 g / 45 g logic intact.
Long-grain vs short-grain? Long-grain rice (jasmine, basmati) runs a little lighter per spoon; short-grain (sushi, sticky) a little heavier. The 8-and-4 split stays within a few grams either way — close enough that nobody at the table notices.
Measured with spoons, but it came out different from last week? Moisture and brand change density. Weigh once with a scale, note the spoon count that matched, and let the spoons take over from there.
The takeaway
No cup, no problem. 8 level tablespoons for 90 g, 4 for 45 g, 24 or 12 teaspoons when a spoon is too big, and a palm when "close enough" is the goal. The measuring cup is one tool in the drawer. The tablespoon is the one that is always there.
