Frequently Asked Questions
What is a base converter?
A base converter is a tool that converts numbers between different number systems or bases. For example, it can convert the decimal number 255 to binary (11111111), hexadecimal (FF), octal (377), and other number systems. This is essential for programmers working with different data representations, students learning computer science, and anyone dealing with various number systems.
How do I use this base converter tool?
Using our base converter is simple: 1) Enter the number you want to convert in the input field, 2) Select the current base (radix) of your input number using the radio buttons or dropdown, 3) Click 'Convert' or press Enter to see all conversions, 4) Copy any result by clicking on it. The tool automatically converts to all supported bases and displays the results in an organized table.
What number bases are supported?
Our tool supports bases from 2 to 62: Binary (base 2), Octal (base 8), Decimal (base 10), Hexadecimal (base 16), Base32, Base36, Base58, Base62, and any custom base from 2 to 62. Each base uses appropriate character sets - for example, base 16 uses 0-9 and A-F, while base 62 uses 0-9, A-Z, and a-z.
Is this base converter tool free to use?
Yes, our base converter is completely free to use with no registration required. You can convert unlimited numbers between any supported bases without any cost. There are no hidden fees, premium features, or usage limits.
Can I convert negative numbers?
Yes, our tool supports negative numbers. When you enter a negative number, it will be converted to all supported bases while maintaining the negative sign. This is useful for working with signed integers in different number systems.
What are the character sets for different bases?
Different bases use different character sets: Base 2 uses 0-1, Base 8 uses 0-7, Base 10 uses 0-9, Base 16 uses 0-9 and A-F, Base 32 uses 0-9 and A-V (excluding I, L, O, U), Base 36 uses 0-9 and A-Z, Base 58 uses 1-9, A-H, J-N, P-Z, a-k, m-z (excluding 0, O, I, l), and Base 62 uses 0-9, A-Z, and a-z.
How accurate are the conversions?
Our conversions are mathematically accurate and handle large numbers up to JavaScript's maximum safe integer (2^53 - 1). The tool uses precise algorithms for each base conversion and validates input to ensure correct results. For extremely large numbers, the tool will display appropriate error messages.
Can I copy the conversion results?
Yes, you can easily copy any conversion result by clicking on it. The tool provides click-to-copy functionality for all results, making it easy to use the converted values in your code or documents. You can also use Ctrl+C to copy selected text as usual.
