Before all I'll apology for any further mistake in this text. English is not my Native language.
Regarding to the answer of the question, the actual size of a Table Tennis ball is 40 millimeters of diameter. To add some more information we can say that it's something recent because the size of the ball was always 38 millimeters and only was changed after the Olympic games of Sydney 2000.
The ITTF (International Table Tennis Federation) made the change with the objective of creating longer rallies and to make the ball more visible in the TV.

What is the circumference of a ping pong ball?
The diameter of any sphere can be calculated by multiplying it's diameter by Pi. For a 40mm diameter Ping Pong Ball, this comes to ~ 125.6 mm. For a 38mm diameter Ping Pong Ball, this comes to ~ 119.32 mm. The diameter of a ping pong ball is 40mm. I do not know the circumference. Before the ball was changed a few years ago to 40mm, it was 38mm. The larger ball travels more slowly and with less spin. This was done to make Table Tennis easier to watch on television, and therefore make the sport more popular. On TV, TT can appear too fast to appreciate, and by enlarging the ball it was hoped that the game would slow. The game has, in fact, slowed, but this has not accomplished the goal of popularizing the sport. Many players would love to see the ball returned to 38mm, as at this size the ball traveled more quickly and more spin was possible, making the ball's travel more manageable.

What is the weight of 1 meter cubed of 40 mm diameter ping pong balls weighing 2.7 grammes each and tightly packed?
40 mm = 4 cm and each ball occupies 64 cubic cm of space inside the cubed metre and a cubed metre is 1,000,000 cubic cm 1,000,000/64 = 15,625 ping pong balls 15,625*2.7 = 42,187.5 grammes or 42.1875 kilogrammes
If the earth was the size of a ping pong ball how big would the sun be?
According to the 2009 edition of the Handbook of the International Table Tennis Federation,the official diameter of the ping pong ball is 40 mm.(I can't just whip out the answer off the top of my head ... I have to do the research first.)If you shrunk everything down until the earth was the size of a ping pong ball, then-- The diameter of the sun is 4.359 meters(14.3 ft)-- The diameter of the moon is 10.9 millimeters (0.43 inch)-- The distance between the earth and sun is 469 meters (512 yards, 0.29 mile)-- The distance between the earth and moon is 1.205 meters (3.95 feet)-- The average distance between Pluto and the sun is 18.5 km (11.5 miles)-- The distance from us to the nearest star is 29,667 km (18,434 miles)
What is the drag coefficient of a ping pong ball?
For a 38mm diameter ball (not regulation, but common):4/3*pi*r^3 = 9145.33 cu mm = 9.145 cc (cubic centimeters).1 cc water = 1 mL water = 1 gram water = 0.035274 AVDP Oz = 0.0022046 AVDP PoundSO:Your 38mm ping pong ball displaces 9.145 mL Water (or 9.145 gram Water, or 0.323 AVDP oz, or 0.02016 AVDP Pound.)It would take roughly 50 of these balls to displace one pound of water.
