Why Convert Number Bases?

Number base conversion is a fundamental skill in computer science and programming. Binary (base 2) is the language of computers — all data is stored as 0s and 1s. Hexadecimal (base 16) is used for memory addresses, color codes (#FF5733), and representing binary data compactly. Octal (base 8) is used in Unix/Linux file permissions (chmod 755). Decimal is the everyday number system. Being able to convert between these bases quickly is essential for debugging, low-level programming, and understanding how computers work.

Benefits

• •Debug binary and hex values in code quickly
• •Convert color codes between hex and decimal
• •Understand memory addresses and pointers
• •Learn number systems for CS courses
• •Calculate Unix file permissions in octal
• •Work with embedded systems and hardware

How to Convert Number Bases

1. 1Type a number in any field (binary, octal, decimal, or hex)
2. 2All other fields update automatically as you type
3. 3Binary field accepts only 0 and 1 digits
4. 4Hex field accepts 0-9 and A-F characters
5. 5Copy any result by selecting the text
6. 6Clear a field to reset all values

Number Base Quick Reference

Binary (base 2): uses digits 0-1. Octal (base 8): uses digits 0-7. Decimal (base 10): uses digits 0-9. Hexadecimal (base 16): uses digits 0-9 and letters A-F. Common conversions: 255 decimal = FF hex = 11111111 binary = 377 octal. 16 decimal = 10 hex = 10000 binary = 20 octal.
