It's about 100,000,000 times as heavy as a Grain of Rice
In other words, the weight of a Grain of Rice is 0.00000001000 times 2,100 kilograms.(conventional; US; long-, medium-, and short-gran varieties; uncooked)
With great differences in variety, the average among a sampling of common short-, medium- and long-grain rices finds that a single grain weighs about 0.0000210 kilograms before cooking.
