How Much Is A Billion?

Politicians -- at the state and federal level -- talk in numbers that most folks can't visualize.

So how much is a billion? First, we have to clarify that we're using the US system of numbers (short scale), not the British system (long scale).

The chart, however accurate, doesn't put the number -- one thousand million -- into perspective. Here are some attempts, collected from around the Net:

• If we wanted to pay down a billion dollars of the US debt, paying one dollar a second, it would take 31 years, 259 days, 1 hour, 46 minutes, and 40 seconds. To pay off a trillion dollars of debt, at a dollar a second, would take about 32,000 years.
• A tightly-packed stack of new $1,000 bills totaling $1 billion would be 63 miles high. In comparison, jet planes fly at 30,000 - 40,000 feet (5.7 - 7.7 miles high).
• About a billion minutes ago, the Roman Empire was in full swing. (One billion minutes is about 1,900 years.)
• About a billion hours ago, we were living in the Stone Age. (One billion hours is about 114,000 years.)
• About a billion months ago, dinosaurs walked the earth. (One billion months is about 82 million years.)
• A billion inches is 15,783 miles, more than halfway around the earth (circumference).
• The earth is about 8,000 miles wide (diameter), and the sun is about 800,000 miles wide, not quite a million.
