A single long grain of rice weighs an average of 29 mg. A staple through most of human history, archaeological evidence indicates that the earliest rice cultivation was about 11,500 years ago.
It's about eight times as heavy as a Grain of Sugar.
In other words, the weight of a Grain of Sugar is 0.1250 times 5 miligrams.(a.k.a. white sugar, a.k.a. white refined sugar, a.k.a. table sugar, a.k.a. sucrose, a.k.a. saccharose)

It's about seventeen times as heavy as a Poppy Seed.
In other words, the weight of a Poppy Seed is 0.059 times 5 miligrams.(Papaver somniferum)
Fifty percent oil by weight, a poppy seed weighs approximately 0.3 mg. The true pigment of a poppy seed is brown in color, while the characteristic bluish color is an optical illusion caused by a layer of calcium oxalate crystals refracting light rays.
It's about one-thirty-fifth as heavy as a Raindrop.
