It's about one-twentieth as heavy as a Bowling Ball
In other words, 0.310 kilograms is 0.045562201 times the weight of a Bowling Ball, and the weight of a Bowling Ball is 21.9480179 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.
