"One Quadrillion Pennies"

"One Quadrillion Pennies"
by Quadrillion.com
"One quadrillion, sixty-seven billion, eighty-eight million, three hundred and eighty-four thousand pennies. One cube measuring 2,730 x 2,730 x 2,730 feet. What a stack of 1 Quadrillion (U.S.), 1,000,067,088,384,000 pennies might look like:

1,000,067,088,384,000
One quadrillion, sixty-seven billion, eighty-eight million,
three hundred and eighty-four thousand pennies.

Here we have the buildings we used for scale back at a trillion, but they're now a bit dwarfed by our new cube of pennies. This is a quadrillion, or a thousand times one trillion. This cube is roughly a half-mile wide and would weigh an astonishing three billion tons."

"There are two systems in use for naming numbers larger than a million: In the American system, the Latin prefix refers to the number of groups of three zeros, not including the last group of three, which represents a thousand. Thus in the USA, a billion is 1,000,000,000 (109) and a quadrillion is a mere 1,000,000,000,000,000, (1015).

In the British system, which is in use in the rest of the world, the Latin prefix represents the power of a million, thus British billion is 1,000,000,000,000 (1012), and a British quadrillion is 1,000,000,000,000,000,000,000,000 (1024).”
