# One Trillion Dollars

Last year, Apple became the first American trillion dollar company (The stock market is fluid, and at the time of writing this article it’s back below that level, but who knows, it could be back above by the time you read this!)
A trillion is a thousand billion, and a billion is a thousand million. This makes one trillion, one million million. That is almost an inconceivable number to imagine. Humans are very good at estimating and appreciating small relative size jumps, but not things at this scale.

## Counting Dollars

Imagine you sit at a table counting dollars bills. One per second. You get to keep what you count. (It’s a fun fantasy).
• If you stopped after a minute, you’d have \$60.
• If you stopped after an hour, you’d have \$3,600 (nice work if you can get it!)
• If you counted, non-stop, for an entire day (24 hours) you’d earn \$86,400.
• To earn a million dollars, you’d have to count, non-stop, for 11.57 days (a little less than two weeks).

## One Billion Dollars

How long would it take to get to a billion dollars? Well, that’s a thousand times a million, so it’s 11.57 thousand days. That’s 31.7 years! That’s right, if you count at one dollar per second, non-stop, 24 hours a day from the day you were born, you’d have accumulated a billion dollars just before your 32nd birthday. Congratulations on your first billion! (Do it couple of hundred more times and give Jeff Bezos a challenge for the World's richest person).

## One Trillion Dollars

But how long to get to one trillion? A trillion is a thousand billion. So you’d need to be counting for 31.7 thousand years!
To count one trillion dollars, one dollar per second, would take 31,688 years!
