Code Box: codes, symbols, entities used in HTML work

ASCII (American Standard Code for Information Interchange) Code

In Memoriam Bob Bemer

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