Approximately 1 cup if boiled in 2 parts water. That means
2 cups of water - 16 oz., about 450 grams. The rice weighs
a lot less than the water. There will be a little bit of
evaporation but most of the water is absorbed by the rice.

If you need something more precise than that you are going
to have to experiment, or you can just cook a little extra
and find something to do with an ounce or two or cooked
rice.
