How to use this number base converter
- Type a number into any of the four fields.
- The other three bases update automatically as you type.
- Copy the result you need, useful for programming, color codes, or networking.
Why do computers use hexadecimal and binary?
Binary (base 2) directly reflects how computers store data as on/off bits. Hexadecimal (base 16) is a compact, human-friendly way to represent binary data, since each hex digit maps exactly to 4 bits, that's why you see it in color codes, memory addresses, and MAC addresses.
What is octal used for today?
Octal is less common now, but still appears in Unix/Linux file permission codes (like chmod 755) and some older programming contexts.
Is there a limit to how large a number I can convert?
This tool uses standard JavaScript number precision, which is reliable up to about 9 quadrillion (2^53). Beyond that, results may lose precision.
Why do bitwise operations behave oddly with large or negative numbers?
Bitwise operations (AND, OR, XOR, NOT, shifts) work on 32-bit signed integers in JavaScript, unlike the base converter above which handles much larger numbers, values outside that 32-bit range get truncated before the operation runs.
