ASCII Encoding

Character → Decimal → Binary

Each character is assigned a unique 7-bit or 8-bit number.

Standard ASCII uses 7 bits (0-127). Extended ASCII uses 8 bits (0-255).

Example: 'A' = 65 decimal = 01000001 binary.

People Also Ask

🤔 How do I convert text to binary manually?

Find ASCII decimal value for each character, convert decimal to 8-bit binary. Example: 'A' = 65 → 64+1 → 01000001.

🔍 What is the difference between 7-bit and 8-bit ASCII?

7-bit ASCII uses codes 0-127, covers English letters, digits, punctuation. 8-bit ASCII (extended) adds 128-255 for accented characters, symbols, etc.

⚡ Why is binary representation used in computers?

Computers use binary (0/1) because it's easy to represent with electronic switches (on/off). All data ultimately becomes binary for processing.

📏 How to convert binary back to text?

Group binary into 8-bit bytes, convert each to decimal, then look up ASCII character. Our tool does this automatically.

🎯 What is the ASCII code for space?

Space is ASCII 32, binary 00100000. It's a non-printing character that separates words.

🔥 Real-world applications of ASCII to binary conversion?

Data transmission, embedded systems, file encoding, cryptography, learning computer science fundamentals.

What is ASCII?

ASCII (American Standard Code for Information Interchange) is a character encoding standard that assigns numeric values to letters, digits, punctuation, and control characters. Each character is represented by a 7-bit or 8-bit binary number.

Common Questions

How to convert 'Hello' to binary?

H = 72 → 01001000
e = 101 → 01100101
l = 108 → 01101100
l = 108 → 01101100
o = 111 → 01101111
So "Hello" in binary: 01001000 01100101 01101100 01101100 01101111

What is the binary for 'A'?

'A' decimal 65 = 64 + 1 = 2⁶ + 2⁰ = 01000001 in 8-bit binary.
