p.s. My contribution after two sessions, a short one and a very long one, is 3620 grains.

Note added on 18 June: According to the free rice website 48 grains of rice make one gram. Therefore, according to my calculations, to contribute one kilogram of rice one has to generate a donation of 48000 grains i.e one has to get 2400 correct answers. Not an easy task. But one would have improved one's vocabulary by the time one donated a kilogram of rice.

As per the website the total donation till today due to correct answers is 36,892,194,250 grains. This according to my calculations works out to 768 587 380 grams or 768,587 kgs and 380 grams. Which can also be 768.5 tons. An impressive quantity indeed. And all the result of visitors to the site playing a vocabulary building game.
