Why ratios vary
Rice age, rinsing, soaking, lid fit, altitude, pot shape and rice cooker behavior can change the ideal ratio. Brown rice usually needs more water and time because the bran layer remains intact.
Example
If a rice type uses a 1.5:1 water-to-rice ratio, 2 cups of rice need 3 cups of water. If package directions differ, use the package directions first.
Common mistakes
Do not mix dry rice cups and cooked rice cups. The input is uncooked rice amount, before the rice absorbs water.
Limitations
Use this as a planning estimate, then adjust for your pot, cooker, soaking time and preferred texture.
