What is Number Base Conversion?
Number base conversion is the process of changing a number from one number system to another. Our free online binary converter supports four essential number systems used in computing and mathematics:
Decimal (Base 10): The standard number system using digits 0-9
Binary (Base 2): Uses only 0s and 1s, fundamental in computer science
Hexadecimal (Base 16): Uses 0-9 and A-F, common in programming
Octal (Base 8): Uses digits 0-7, historically important in computing
Common use cases: Converting IP addresses, working with memory addresses, understanding computer architecture, debugging programs, and learning computer science concepts.
