Frequently Asked Questions
How do I convert decimal to binary?
Repeatedly divide the decimal number by 2 and record the remainders. The binary number is the remainders read in reverse order. For example, 13 in decimal is 1101 in binary. The converter does this automatically.
What is hexadecimal used for?
Hexadecimal (base 16) is widely used in computing to represent binary data compactly. Each hex digit represents 4 binary bits. It is commonly used for color codes (#FF5733), memory addresses, and byte values.
Can I convert very large numbers?
Yes. The tool supports arbitrary-precision integers, so you can convert numbers with hundreds of digits without losing accuracy.
