Let's stack those $1 bills and see how high the pile goes.
A dollar bill is .0043 inches thick according to the US Treasury.
14,000,000,000,000 x .0043 = 60,200,000,000 inches.
60,200,000,000/12 = 5,016,666,666 feet.
5,016,666,666/5280 = 950,126 miles.
All numbers were rounded off. Windows calculator sucks.
