How big is a trillion?

One trillion is the number "1" followed by 12 zeroes, as in: 1,000,000,000,000.

One trillion seconds of ordinary clock time = 31,546 years.

So, spending at $1 a second, it would take 31,546 years to spend $1 trillion.

If someone were to build city blocks that contained 10 homes valued at $100,000 per home, you would end up with 10 houses to a block, 10 blocks to a mile and a hundred blocks per square mile. It would take 10,000 square miles to reach $1 trillion in value. This would be than larger than six U.S. states: Vermont, 9,615 square miles; New Hampshire, 9,351 square miles; New Jersey, 8,722 square miles; Connecticut, 5,544 square miles; Delaware, 1,954 square miles; and Rhode Island, 1,545 square miles.
