ASCII Character Chart with Decimal, Binary and Hexadecimal Conversions
ASCII stands for "American Standard Code for Information Interchange". It is the character set that is used in PCs and most other small computers. (The other big standard is IBM's EBCDIC character set, which is used in IBM minis and mainframes). The table below lists all of the characters in the character set, along with their decimal, binary and hexadecimal number equivalents, so you can also use it as a conversion chart:
Note: ASCII characters 0 to 31 are
control characters, not printed characters. They are represented using short forms in the
"Char" column. The "Code" column represents the keystrokes usually
used to generate the character on a standard "enhanced" PC keyboard.
