What is Number Base Conversion?
Number base conversion is the process of changing the representation of a number from one numeral system (base) to another. Common bases include binary (base 2, used by computers), octal (base 8), decimal (base 10, everyday numbers), hexadecimal (base 16, used in programming), and Base64 (base 64, used for encoding binary data as text).
Digit Sets by Base
Each base uses a different set of digits. Binary uses 0-1, octal uses 0-7, decimal uses 0-9, hexadecimal uses 0-9 and A-F, and Base64 uses A-Z, a-z, 0-9, +, and /.

Veelgestelde Vragen
What is hexadecimal used for?
Hexadecimal (base 16) is widely used in programming to represent binary data compactly. Each hex digit maps to exactly 4 binary bits, making it convenient for memory addresses, color codes, and byte values.
Why do computers use binary?
Computers use binary (base 2) because digital circuits have two states: on and off. Each binary digit (bit) represents one of these states, making binary the natural number system for electronic hardware.
What is the difference between octal and hexadecimal?
Octal uses base 8 (digits 0-7) and each digit represents 3 binary bits. Hexadecimal uses base 16 (digits 0-9 and A-F) with each digit representing 4 binary bits. Hex is more common in modern programming.
