It's about one-and-one-third times as heavy as a Bowling Ball
In other words, 9 kilograms is 1.32277357 times the weight of a Bowling Ball, and the weight of a Bowling Ball is 0.755987285 times that amount.(most common selection among male bowlers)
With an allowable range of 4.989516070 kilograms, the most-preferred bowling ball weight among adult, male bowlers is 6.803885550 kilograms. Because regulation balls measure the same diameter irrespective of their weight, ball density varies by size and balls weighing less than about 5 kg (11 lbs) will float in water.

In other words, 9 kilograms is 0.7233917978 times the weight of a Gold Bar, and the weight of a Gold Bar is 1.382376747 times that amount.(London Good Delivery bar)

A standard, traditional face brick weighs an average of 2.9 kg. 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.
