How to convert binary 1/0 notes to everyday numbers

Collectors enjoy binary notes, which are simply notes with serial numbers containing only two numbers, for example A38838838A.

A subset of these general binary notes contain only 1s and 0s, for example A00111011A.  These are the 1/0 binaries I am talking about here.

As a former engineer, I collect binary 1s and 0s because they bring back memories of my silicon-chip days.  There, transistors in the "off" position can represent 0s, and transistors in the "on" position can represent 1s.  Many transistors together form binary "words" which then can be translated to language we understand on our PCs.

You can also convert these 0/1 binaries (known in the engineering world as Base 2, since there are only 2 numbers) into what is known as Base 10 - the physical world in which we live, where we have 10 different numbers, 0 through 9.

For example, if your lucky number is 6, that would be represented in binary as 110.  So you might look for a note with serial number A00000110A to represent your birthday in binary language.

If you were born on December 6th, you might look for a note containing 126, or in binary, the note would have serial number A01111110A.

Since currency notes typically have only eight serial numbers, the highest Base 10 number in binary is 255, since 255 = 11111111 in binary.

You can do the same math with other binaries, for example 8/2 binaries, or 9/7 binaries, but the math is a bit more complicated.

If you're looking to convert any number 255 or below, you might want to use our 1/0 binary calculator.
