It's about nine times as heavy as a Bowling Ball
In other words, 0.00000006120 megatonnes is 8.99486030 times the weight of a Bowling Ball, and the weight of a Bowling Ball is 0.11117460 times that amount.(most common selection among male bowlers)
With an allowable range of 0.000000004989516070 megatonnes, the most-preferred bowling ball weight among adult, male bowlers is 0.000000006803885550 megatonnes. Because regulation balls measure the same diameter irrespective of their weight, ball density varies by size and balls weighing less than about 0.00000000500 megatonnes will float in water.
