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 30,000 times as heavy as a Brick.
In other words, 100 tons is 31,000 times the weight of a Brick, and the weight of a Brick is 0.0000320 times that amount.(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.

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 15,000 times as heavy as a Bowling Ball.
In other words, 100 tons is 13,333.33330 times the weight of a Bowling Ball, and the weight of a Bowling Ball is 0.00007500000020 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.
