Number Base Converter — Complete Guide
Number systems are at the heart of computing. Every operation your computer performs ultimately comes down to binary (base-2) arithmetic, yet developers interact with numbers in decimal (base-10), hexadecimal (base-16) for memory addresses and color codes, and occasionally octal (base-8) for Unix file permissions. Being able to convert between these systems quickly is an essential skill for anyone working with low-level programming, networking, or digital electronics.
Our Number Base Converter provides instant bi-directional conversion between all four major number systems. Enter a value in any base — decimal, binary, octal, or hexadecimal — and immediately see the equivalent in all other bases. This is invaluable for debugging memory addresses, understanding bitwise operations, calculating subnet masks, or simply checking your homework.
Key Features
- Bi-directional Conversion: Input in any field and all other bases update in real-time.
- All Major Bases: Supports binary (2), octal (8), decimal (10), and hexadecimal (16).
- One-Click Copy: Copy any converted value to your clipboard instantly.
- Clean Interface: All four bases displayed side-by-side for easy comparison.
Common Use Cases
- Converting hex color codes to their decimal RGB components.
- Debugging memory addresses and pointer values in systems programming.
- Understanding Unix file permission octals (e.g., 755 → rwxr-xr-x).
- Working with bitwise operations and binary arithmetic in algorithm design.
