Water per cup of rice

Calculator diagram
Diagram updates with the inputs.

The pot needs a starting splash of water, and the rice decides how much. One cup of dry long-grain white rice starts at 1.50 cups of water on this page.

If you measured the water in milliliters, the measurement converter turns cups into mL. This page stays in cups.

Four starting ratios

Long-grain white 1.5, jasmine 1.25, basmati 1.5, brown 2. Williams Food Equipment lists long-grain white at 1.5 and basmati at 1.5, with jasmine beginning at 1.25 and brown beginning at 2. Those are the numbers in the menu.

A covered pot, not a machine

The ratios are for a stovetop pot: boil, cover, simmer. An Instant Pot, a rice cooker, and a brand’s own line on the bag can want less water. Rinsing the rice changes the result too.

Worked example: 1 cup of long-grain white

Dry rice 1, rice set to long-grain white. Water is 1.50 cups. The pot drawing starts on that 1.50 line.

\[ 1\times 1.5=1.50 \]

Frequently asked questions

Why is jasmine lower than long-grain white?

The cited range starts jasmine at 1.25 cups per cup of rice and long-grain white at 1.5. This page uses those starts.

How much water for 2 cups of brown rice?

The ratio is 2, so 2 cups of brown rice starts at 4.00 cups of water.

Can I use this in a rice cooker?

Use the lines in the cooker. These ratios are a stovetop start, and a cooker often wants less.

Does rinsing change the water?

Yes. Wet grains bring water with them. The page does not subtract a rinse.

Is 1.50 a promise from a brand?

No. It is a starting point. If the pot is wide or the lid is loose, the rice can finish firm and want a splash more.

Assumptions and limitations

Stovetop starting points only. Not an Instant Pot, not a rice cooker, and not a brand promise. Rinsing changes the result.
