How many cups are in a pound of rice?

Answer 1

It depends if the rice is cooked or uncooked, as cooked rice will contain a lot of water and be more dense than uncooked rice. A pound of uncooked rice will yield about 3 times as many cups once it has been cooked than before it was cooked, but will also weigh more than three pounds.

A cup of pure water (8 fluid ounces) weighs about 8.34+ ounces (weight), so 2 cups of water would weigh about 16.69 ounces or 1.043 pounds. Which means a pound of water yields 1.918 cups. (at 4 degrees Celsius)

The density of water is 1,000 kilograms per cubic meter. The density of rice (hulled) is approximately 753 kilograms per cubic meter.

So a pound of uncooked rice, being less dense than water, should yield approximately 2.55 cups.

Once cooked that same pound of rice (at a ratio of 2 cups water to one cup rice) would weigh almost 3.66 pounds. Assuming no water is lost during cooking.

Assuming my math is correct, it may not be.

It is not possible to accurately calculate the number of cups this will yield - but it is likely to be about 6 cups or more. One needs to cook a pound of rice and measure the volume.
