ASCII (American Standard Code for Information Interchange) Code

In Memoriam Bob Bemer

This page shows the ASCII code in hexadecimal (base 16), octal (base 8), and decimal (base 10) number systems in one table. You can also see these in tables with the number systems each in a table by themselves. These pages are part of The Code Box, a collection of pages about codes used in HTML and Web work.
