All denominations of paper currency notes printed since 1929 are the same size, measuring approximately 2.61 inches (6.63 centimeters) by 6.14 inches (15.60 centimeters). Each note is 0.0043 inches thick, and a stack of currency notes one mile high would contain over 14.5 million notes. If all of the currency notes printed were laid end to end, they would stretch around the earth's equator approximately 24 times.
Each currency note, regardless of its denomination, weighs about one gram. There are 454 grams in one U.S. pound, so there should be 454 notes in a pound.
