With all of the talk about a Trillion dollar budget/bailout/deficit/cost of Iraq I had to try to wrap my brain around it and here is what I found for explanations:
A trillion dollars is so large a number that only politicians
can use the term in conversation...
Here is some perspective on TRILLION:
1 TeraByte (TB)
Trillion = 1,000,000,000,000.
The USA has not existed for a trillion seconds.
Western civilization has not been around a trillion seconds.
One trillion seconds ago – 31,688 years – Neanderthals stalked the plains of Europe.
Let's start with one billion. If you spent $1,000 per day, every day without fail, you would spend $365,000 in a normal year.
You would spend $36,525,000 in a century (assuming 25 leap years per century).
So, if you started spending $1,000 per day starting January 1, 0000, you would be spending $1,000 per day through the end of the Roman Empire, the collapse of the Mayan civilization, the Middle Ages, the Crusades, the Black Plague, the Renaissance, the European conquest of the New World, the Industrial Revolution, the American Revolution, the French Revolution, the Russian Revolution, World Wars I and II, the Cold War, the end of the 20th Century and would finally reach one billion dollars a little more than one-third of the way through the 28th century.
Now do that 999 more times and that gets you to one trillion dollars
