ASCII To Binary

ASCII to Binary Converter

About This Converter

ASCII (American Standard Code for Information Interchange) is a character encoding standard that represents text in computers and other devices. Each character in ASCII is assigned a unique numeric code, typically 7 bits in length. Binary, on the other hand, is a base-2 numeral system, and it uses only 0s and 1s to represent numbers.

Converting ASCII to binary involves representing each character in its corresponding binary form based on its ASCII code. Here’s a simple step-by-step process:

  1. Get the ASCII code: Identify the ASCII code for each character in the text you want to convert. You can find ASCII code charts online that list the decimal, hexadecimal, and binary representations of each ASCII character.
  2. Convert to binary: Once you have the ASCII code, convert it to binary. This involves representing the decimal value of the ASCII code using binary digits (0s and 1s).For example:
    • The ASCII code for the letter ‘A’ is 65.
    • In binary, 65 is represented as 1000001.
  3. Repeat for each character: Repeat the process for each character in the text, converting its ASCII code to binary.
  4. Combine the binary representations: If you have a sequence of characters, concatenate their binary representations to get the binary representation of the entire text.

Let’s take an example:

Text: “Hello” ASCII Codes: 72 101 108 108 111

Binary Representations:

  • ‘H’ (72): 01001000
  • ‘e’ (101): 01100101
  • ‘l’ (108): 01101100
  • ‘l’ (108): 01101100
  • ‘o’ (111): 01101111

Combine the binary representations: 01001000 01100101 01101100 01101100 01101111

So, the binary representation of the text “Hello” in ASCII is 01001000 01100101 01101100 01101100 01101111.
