In other words, 0.000000200 tons is 0.000134 times the weight of a Human Brain, and the weight of a Human Brain is 7,460 times that amount.(adult)
The average weight of an adult human brain is between 0.00149 tons. 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.
It's about one-ten-thousandth as heavy as a Chihuahua.
In other words, 0.000000200 tons is 0.00008060 times the weight of a Chihuahua, and the weight of a Chihuahua is 12,400 times that amount.(a.k.a. Chihuahue(o) (FCI standard)
The F&d&ration Cynologique Internationale (FCI) calls for Chihuahuas to weigh about 0.00248 tons. Relative to their body sizes, Chihuahuas have the largest brain size of any dog breed.
It's about one-fifteen-thousandth as heavy as a Brick.
In other words, the weight of a Brick is 16,000 times 0.000000200 tons.(Standard, traditional face brick - 1,900 cu. cm (120 cu. in))
A standard, traditional face brick weighs an average of 0.0032 tons. The steeple of the Church of St. Martin in Landshut, Germany is said to be the tallest brick tower in the world at a height of 130.6 m (428.5 ft) and was constructed using an estimated 650,000 bricks.
It's about one-twenty-five-thousandth as heavy as a Gallon of Paint.
It's about one-twenty-five-thousandth as heavy as a Cat.
In other words, the weight of a Cat is 30,000 times 0.000000200 tons.(Felis catus) (Domestic; healthy weight)
The average domestic cat should weigh between 0.005 tons. Cats are known for their righting reflex, which allows them to land on their feet and survive falls from heights of 1 m (3 ft) up to about 21 m.
It's about one-thirty-five-thousandth as heavy as a Bowling Ball.
In other words, 0.000000200 tons is 0.00002666666670 times the weight of a Bowling Ball, and the weight of a Bowling Ball is 37,500 times that amount.(most common selection among male bowlers)
With an allowable range of 0.0055 tons, the most-preferred bowling ball weight among adult, male bowlers is 0.0075 tons. Because regulation balls measure the same diameter irrespective of their weight, ball density varies by size and balls weighing less than about 0.00551155655 tons will float in water.
