In other words, 0.0000000000150 megatonnes is 0.01499958 times the weight of a liter of Water, and the weight of a liter of Water is 66.668530 times that amount.(fresh; 4° C / 39.2° F; maximum density)
Contrary to popular belief, 1 liter (0.0.264172052358148 gal) of water at 4° C / 39.2° F (its point of maximum density) weighs 0.0000000010000280 megatonnes rather than 1 kg exactly. The total volume of water on the planet Earth is about 13,590,000,000,000,000,000 (13.59 quntillion) L (3,590,000,000,000,000,000 gallons).
It's about 80 times as heavy as a Raindrop
In other words, the weight of a Raindrop is 0.01 times 0.0000000000150 megatonnes.(a.k.a. drop, a.k.a. droplet) (average)
The weight of a raindrop depends heavily on the type of weather, but averages about 0.000000000000200 megatonnes. 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.
It's about one-ninetieth as heavy as a Human Brain
In other words, 0.0000000000150 megatonnes is 0.0111 times the weight of a Human Brain, and the weight of a Human Brain is 90.10 times that amount.(adult)
The average weight of an adult human brain is between 0.000000001350 megatonnes. In humans and primates, sight and vision utilize about 30 different parts of the brain which together account for about half of the brain's size.
