About this calculator

ASCII (American Standard Code for Information Interchange) is the foundational 7-bit character encoding that assigns a number from 0 to 127 to each letter, digit, punctuation mark, and control character used in early computing — the basis that later encodings like Latin-1 and UTF-8 build on and stay backward-compatible with.

Knowing a character's decimal code, hex value, and binary representation is a routine need whenever you're debugging encoding issues, writing low-level string-handling code, working with control characters like newline (10) or tab (9), or teaching how computers represent text. Programmers, computer science students, and anyone troubleshooting a data-encoding problem reach for a bidirectional ASCII table to move quickly between a character and its numeric codes.
