Comprehensive Guide to Binary Conversion
Binary conversion is the process of translating numbers and characters into the base-2 format computers use natively. This guide explains the math behind binary, decimal, and hexadecimal conversions, and includes a compact ASCII lookup for common characters.
Base-2 Conversion Logic
Binary numbers use two digits: 0 and 1. Each position represents a power of two.
Base-10 Conversion Logic
Decimal numbers use ten digits from 0 to 9. Converting a decimal number to binary requires repeated division by 2.
6 ÷ 2 = 3 remainder 0
3 ÷ 2 = 1 remainder 1
1 ÷ 2 = 0 remainder 1
Binary result: 1101
Base-16 Conversion Logic
Hexadecimal uses 16 digits: 0-9 and A-F. Convert binary to hex by grouping bits in blocks of four.
ASCII to Binary Quick Reference
| Character | ASCII | Binary |
|---|---|---|
| A | 65 | 01000001 |
| a | 97 | 01100001 |
| 0 | 48 | 00110000 |
| 1 | 49 | 00110001 |
| space | 32 | 00100000 |
| ! | 33 | 00100001 |
How do I convert binary to text?
Enter space-separated 8-bit bytes and the converter will translate each byte to its ASCII character automatically.
What is the fastest way to convert decimal to binary?
Use repeated division by 2, track remainders, and read the result from bottom to top. Our homepage tool does this in real time.
Why is hex useful for binary conversion?
Hexadecimal compresses binary into 4-bit groups, making long binary values easier to read and verify.
Can I copy results directly from the homepage tool?
Yes — the homepage tool includes a live Copy Output button to move results to your clipboard instantly.
