Whoops! Make that 200 000 elephants weight in a trillion dollars and 3
000 000 elephants (= population of Iowa) weight in national debt. My
original animal equivalents would have worked in cats (~5 kg apiece).
I told you, numbers this size are mind-numbing!
Thanks, John. (I corrected "boggles" to "boggle" while I was at it.)

You were doing great until you denominated it in non-metric units
(elephants). I get 1 000 000 t/5 t = 200 000 elephants. Thereafter, all
the elephants are in error; your numbers correspond to millielephants
(roughly, cats).
But in dollar bills, 1 trillion is 1 Tg which is tera-fying (forgive the
pun)
You might consider denominating it in $100 bills, the largest unit of
currency which is currently printed, as no one would actually carry a
large amount in singles. It is an incremental $47 100 in debt for every
man, woman, and child in addition to their own debts.

The numbers floating through the news these days boggle my mind,
even though I have a strong background in science and engineering.
Bruce Barrow remarked on something a few days ago that inspired my
calculations below. Please tell me if I have made any math errors.

** How large is a trillion dollars?
A dollar bill is 15.6 cm or 0.156 m long. So
1 000 dollar bills end to end would be 156 m long,
1 000 000 dollar bills (a million dollars) would be 156 km long,
1 000 000 000 (a billion) would be 156 000 km long, and
1 000 000 000 000 (a trillion) would be 156 000 000 km long.
The average distance from the Earth to the Sun (called "1
astronomical unit") is very close to 149 598 000 km, or to round it
off that would be
150 000 000 km from Earth to Sun.
So, a trillion dollar bills placed end to end would reach from the
Earth to the Sun and then extend another 4 % or so.
** Could you carry a trillion dollars?
A dollar bill (or a bill of any face value) weighs 1 g. So
1 000 dollar bills would weigh 1 kg,
1 000 000 dollar bills (a million) would weigh 1 metric ton (~2200 lb),
1 000 000 000 (a billion) would weigh 1 000 metric tons, and
1 000 000 000 000 (a trillion) would weigh 1 000 000 metric tons.
The average size of an elephant is 5 metric tons.
So a trillion dollar bills would weigh about the same as 200 000 000
elephants. The population of the U.S. is 310 000 000 people. So,
turn 2/3 of all Americans into elephants and their weight would be
that of a trillion dollar bills.
** How large is our national debt?
The national debt is about 14.8 trillion dollars.
That is equivalent to a line of dollar bills long enough to reach to
the sun 15 times. Or from Saturn to the Sun and halfway back.
If that were represented by dollar bills, it would weigh about the
same amount as 3 billion elephants. The population of the world is 7
billion people. So, turn nearly half the people in the world into
adult elephants and they would then weigh the same as our national
debt in the form of dollar bills.
