How to Convert Text to Binary

Convert text to binary ASCII code:

Get character
Get decimal code of character from ASCII table
Convert decimal to binary byte
Continue with next character

Example

Convert "Plant trees" text to binary ASCII code:

Solution:

Use ASCII table to get ASCII code from character.

"P" => 80 = 2⁶+2⁴ = 01010000₂
"l" => 108 = 2⁶+2⁵+2³+2² = 01101100₂
"a" => 97 = 2⁶+2⁵+2⁰ = 01100001₂

For all the text characters you should get the binary bytes:

"01010000 01101100 01100001 01101110 01110100 00100000 01110100 01110010 01100101 01100101 01110011"

Understanding ASCII-to-Binary Conversion

ASCII-to-binary conversion involves converting ASCII characters into their corresponding binary representations (base 2). ASCII assigns a unique decimal value (0 to 127) to each character, which can be represented as an 8-bit binary number.

The general approach to converting ASCII characters to binary includes:

Look up the decimal value of the ASCII character using an ASCII table.
Convert the decimal value to binary using division by 2 and noting the remainders.
Ensure the binary number is 8 bits long by padding with leading zeros if necessary.

Steps for ASCII-to-Binary Conversion

Step 1: Find the decimal value of the character from the ASCII table.

Step 2: Convert the decimal value to binary using the division-remainder method.

Step 3: Ensure the binary number is 8 bits long by adding leading zeros if required.

Example: Converting ASCII to Binary

Convert \( A \) to binary:

Step 1: Look up the ASCII table: \( A = 65 \) (decimal).
Step 2: Convert \( 65 \) to binary:
- Divide \( 65 \) by \( 2 \): quotient \( 32 \), remainder \( 1 \).
- Divide \( 32 \) by \( 2 \): quotient \( 16 \), remainder \( 0 \).
- Divide \( 16 \) by \( 2 \): quotient \( 8 \), remainder \( 0 \).
- Divide \( 8 \) by \( 2 \): quotient \( 4 \), remainder \( 0 \).
- Divide \( 4 \) by \( 2 \): quotient \( 2 \), remainder \( 0 \).
- Divide \( 2 \) by \( 2 \): quotient \( 1 \), remainder \( 0 \).
- Divide \( 1 \) by \( 2 \): quotient \( 0 \), remainder \( 1 \).
Write the remainders in reverse order: \( 01000001 \).
Final binary result: \( 01000001 \).

Conversion Table for Quick Reference

Here is a quick reference for some ASCII characters and their binary equivalents:

Space → 00100000
A → 01000001
B → 01000010
a → 01100001
b → 01100010
1 → 00110001
2 → 00110010

Applications of ASCII-to-Binary Conversion

ASCII-to-binary conversion is commonly used in:

Encoding text data for storage and transmission in computers.
Developing communication protocols and data formats.
Understanding how characters are stored in digital systems.

Practice Problem

Convert \( g \) to binary:

Solution:
- Step 1: Look up \( g \) in the ASCII table: \( g = 103 \) (decimal).
- Step 2: Convert \( 103 \) to binary:
  - Divide \( 103 \) by \( 2 \): quotient \( 51 \), remainder \( 1 \).
  - Divide \( 51 \) by \( 2 \): quotient \( 25 \), remainder \( 1 \).
  - Divide \( 25 \) by \( 2 \): quotient \( 12 \), remainder \( 1 \).
  - Divide \( 12 \) by \( 2 \): quotient \( 6 \), remainder \( 0 \).
  - Divide \( 6 \) by \( 2 \): quotient \( 3 \), remainder \( 0 \).
  - Divide \( 3 \) by \( 2 \): quotient \( 1 \), remainder \( 1 \).
  - Divide \( 1 \) by \( 2 \): quotient \( 0 \), remainder \( 1 \).
- Write the remainders in reverse order: \( 01100111 \).
Final binary result: \( 01100111 \).
