How much is a trillion dollars?
All this gobbledygook about a billion of this; a trillion of that. Talk about mental overload and intellectual stasis! How much, exactly, is a trillion dollars? Well .... I did a quick Google search on banknote thicknesses. They apparently vary mostly between 0.07mm and 0.15mm, so let's settle on 0.1mm each which yields (close enough) about 250 per inch in a vertical pile.
Imagine, then, a vertical pile of $100 (US, of course) bills:
$1,000,000,000,000 ($1 trillion) = 10,000,000,000 x $100 bills = 40 million inches = 631 miles (or just over 1,000 kilometres.)
So, next somebody makes a "trrr" sound before an "illion" sound when referring to an amount of money .... you have some idea how staggeringly large that amount really is.
