Supports binary, octal, decimal, hexadecimal four common base conversions, input number to instantly display all base results
Find the input box corresponding to the base you want to input on the tool page. There are four input boxes for binary, octal, decimal, and hexadecimal.
Enter the corresponding value in the selected input box. The tool will automatically validate the input legality. If illegal characters are entered, an error will be prompted.
While entering, the other three base results will update in real-time. Click the "Copy" button next to the corresponding result to copy to clipboard.

Base conversion is one of the most fundamental concepts in computer science. Different bases have advantages in different scenarios.
Binary is a number system widely used in computer technology, using 0 and 1 two digits to represent numbers, base is 2, carry rule is "carry one every two". Computers use binary internally to represent data because electronic components only have on and off two states.
Hexadecimal is a carry system that carries every 16, using digits 0-9 and letters A-F (or a-f) to represent, total 16 digits. Hexadecimal is commonly used in computer field because it can represent binary numbers more concisely, one hexadecimal digit corresponds to four binary digits.
Binary to hexadecimal: From right to left every 4 bits as a group, each group corresponds to one hexadecimal digit. Decimal to binary can use division by 2 remainder method, repeatedly divide decimal number by 2, record remainder, finally arrange remainders in reverse order to get binary result.
