Nonary is an interesting choice... the highest single digit in any base N is N-1, making the single digits 0 through 8. A 9 is represented by 10. They start adding letters when the highest single digit exceeds 9, for example Undecimal (Base 11) is where you first see an A to represent 10 (N-1), and hexadecimal (Base 16) goes up to an F (15, again N-1).

That is where the spreadsheet formula comes in. You can use MS Excel, or free versions like openOffice or even Google Sheets.

Put your many rows in column A. At the first cell in column B, type = BASE(A1, 9). Then grab the bottom right corner of B1 and drag it down to match the row length in column A.

Then you will be left with every decimal number in column A converted to it's nonary equivalent in column B. It does not matter if you have dozens, hundreds or thousands to convert.

Thank you very much, Hypersoniq. I would like to be able to convert many rows of numbers to the nonary system. Please. I don't know why the convzone.com page doesn't show how to convert rows to the nonary system.

You could try an online converter at

Or, in an excel spreadsheet, if the decimal number you want converted was in A1, in B1 enter

=BASE(A1, 9
