# Know Your Numbers

**Millions**

First consider a million:

One million is a thousand thousands.2

One million is a 1 with six zeros after it, denoted by 1,000,000.

One million seconds is about 11 and a half days.

One million pennies stacked on top of each other would make a tower nearly a mile high.3

If you earn $45,000 a year, it would take 22 years to amass a fortune of 1 million dollars.

One million ants would weigh a little over 6 pounds.

One million dollars divided evenly among the U.S. population would mean everyone in the United States would receive about one-third of one cent.

**Billions**

Next up is one billion:

One billion is a thousand millions.

One billion is a 1 with nine zeros after it, denoted by 1,000,000,000.

One billion seconds is about 32 years.4

One billion pennies stacked on top of each other would make a tower almost 870 miles high.3

If you earn $45,000 a year, it would take 22,000 years to amass a fortune of one billion dollars.

One billion ants would weight over 3 tons—a little less than the weight of an elephant.

One billion dollars divided equally among the U.S. population would mean that everyone in the United States would receive about $3.33.3

**Trillions**

After this is a trillion:

One trillion is a thousand billions, or equivalently a million millions.

It is a 1 with 12 zeros after it, denoted by 1,000,000,000,000.

One trillion seconds is 32,000 years.5

One trillion pennies stacked on top of each other would make a tower about 870,000 miles high—the same distance obtained by going to the moon, back to Earth, then to the moon again.3

One trillion ants would weigh over 3,000 tons.

One trillion dollars divided evenly among the U.S. population would mean that everyone in the United States would receive a little over $3,000.3
