ASCII to Octal Converter
Convert ASCII characters to their octal (base-8) representation instantly.
About ASCII to Octal Converter
The ASCII to Octal Converter transforms text characters into their octal (base-8) representation. While less common than hexadecimal today, octal was historically important in early computing and is still used in Unix file permissions and some programming contexts.
Each ASCII character is represented by a three-digit octal number (000-377). For example, 'A' becomes 101 in octal. This tool provides instant conversion with multiple output format options.

Frequently Asked Questions
What is octal notation?
Octal is a base-8 number system using digits 0-7. Each octal digit represents 3 bits. Three octal digits can represent one byte (up to 777 octal = 255 decimal).
Where is octal still used today?
Octal is primarily used in Unix/Linux file permissions (e.g., chmod 755). It also appears in some programming escape sequences and legacy system documentation.
What is the octal value of newline?
The newline character (ASCII 10) is represented as 012 in octal. In C-style escape sequences, this would be written as \012 or more commonly \n.
