It's about 85 times as heavy as a Grain of Rice.
In other words, the weight of a Grain of Rice is 0.011 times 39 grains.(long grain; 14% moisture content)
A single long grain of rice weighs an average of 0.450 grains. A staple through most of human history, archaeological evidence indicates that the earliest rice cultivation was about 11,500 years ago.
It's about ten times as heavy as a Raindrop.
In other words, the weight of a Raindrop is 0.10 times 39 grains.(a.k.a. drop, a.k.a. droplet) (average)
The weight of a raindrop depends heavily on the type of weather, but averages about 3 grains. The familiar teardrop shape of a raindrop is actually an optical illusion, caused by the reflection of the light and the motion of the drop.
