They're typically measured in pounds. There are rule conversions to measurement in kilograms.
From the information provided it is impossible to answer the question. You require the velocity or speed of the ball and that is not measured in milliseconds - which a measure of time!
Yes. At 16 ounces to the pound, an 8 pound ball would be 8*16=128 ounce ball.

If air resistance can be ignored (and it probably can from 2 rooms high) then both the bowling ball and golf ball will hit the floor at the same time. Although the bowling ball is harder to get moving than than the golf ball (it has more mass), the bowling ball also has a greater force pulling it down than the golf ball (as measured by its weight). The result is that both objects have the same acceleration.
The answer will depend on what characteristic of the ball is being measured: its radius, volume, mass, weight, shine?
Since the lightest tenpin bowling ball is currently 6 pounds and a table tennis ball is not even an ounce, the tenpin bowling ball is heavier.
Pounds are used to measure the mass of a bowling ball in the US, although the mass of an object that size is usually measured in kilograms in other countries.Pounds (US)
A bowling ball is a ball that is used in the game of bowling, where you roll the ball down an aisle and try to knock down as many pins as you can.
One unit won't work for all of them. Coins and letters are small enough to be measured in grams. Bowling balls and encyclopedias are measured in pounds, and tractors in tons.
The virtual gravity bowling ball is one of the most highly reactive bowling ball in the world.
The circumference of a bowling ball can not be increased.
