Number Base Converter
Convert numbers between binary (base 2), octal (base 8), decimal (base 10), and hexadecimal (base 16).
Why Number Bases Matter
Computers store values in binary, but developers commonly work with decimal, octal, and hexadecimal. Hex is convenient because every byte becomes exactly two digits, which makes it ideal for colors, memory addresses, and binary flags. This converter translates the same number across bases so you can check your work.
When You Will Need It
- Reading memory addresses or debugger output
- Working with bit masks, permissions, or hardware registers
- Converting hex color values to decimal for calculations
Does changing the base change the number?
No. The underlying value is the same; only the representation changes.
