Interesting you (almost) all say 1.1.
I was told an easier way - (after washing it) is to put the rice in the pan
and fill with water to a little fingernails worth above the rice. (1/2")
Bring to boil - stir once - put the lid on and simmer until all the water is
gone.

However for any tomato based rice dish; I don't wash it as it needs to be
dry to fry, so I fry the rice until slightly golden then add the tomatoes,
an equal amount of water and the whatever you're going to put in it.
