FAQ
What is a number base or radix?
A number base (or radix) defines how many unique digits are used to represent numbers. Decimal uses 10 digits (0-9), binary uses 2 (0-1), and hexadecimal uses 16 (0-9, A-F).
What bases does this converter support?
This converter supports any base from 2 to 36. Common bases include binary (2), octal (8), decimal (10), and hexadecimal (16). Bases above 10 use letters A-Z for digits beyond 9.
How do I convert between number bases manually?
To convert from any base to decimal, multiply each digit by its positional power of the base and sum. To convert from decimal to another base, repeatedly divide by the target base and collect remainders.
