## How long would it take you to count to a million?

If you made 1 million dollars it would take 11 straight days to count your money. We will start at 86,400 seconds in a day. If you take a billion and divide it by the number of seconds in a day you get 11,574 days. Divide this by 365 days and you get 31,7 years.

But it would only take 2 years, 8 months, 26 days to reach a million.” To give you another frame of reference, a million seconds is 13 days, a billion seconds is 31 years, and a trillion seconds is 31,699 years. This is a quadrillion, if you counted using pennies. This is a quintillion.

## How long would it take to count to a trillion?

There are 24 hours in a day so you would count 24X60x60 = \$8,6400 in one day. There are 365 days in a year so you would count 24X60x60x365 = \$31,536,000 in one year. To find how long it would take to count to a trillion dollars divide 1 trillion by 31,536,000. That is 1,000,000,000,000/31,536,000 = 31,709.79 years.
