How to Convert Between Number Bases
Binary to Decimal
To convert binary to decimal, multiply each digit by 2 raised to its position power (starting from 0 on the right), then sum all the results.
Example: 10102 = 1 x 23 + 0 x 22 + 1 x 21 + 0 x 20 = 8 + 0 + 2 + 0 = 1010
Decimal to Binary
To convert decimal to binary, repeatedly divide by 2 and record the remainders. Read the remainders from bottom to top.
Example: 10 / 2 = 5 (remainder 0), 5 / 2 = 2 (remainder 1), 2 / 2 = 1 (remainder 0), 1 / 2 = 0 (remainder 1). Reading remainders bottom-to-top: 10102
Decimal to Hexadecimal
Divide by 16 repeatedly and record remainders (0-9 and A-F for 10-15).
Hexadecimal to Decimal
Multiply each digit by 16 raised to its position power, then sum all results.
When to Use Different Number Systems
Binary (Base 2) in Computing
Computers use binary because electronic circuits have two states: on (1) and off (0). Every piece of data in your computer - text, images, videos - is ultimately stored as binary numbers. Understanding binary helps programmers debug low-level code and work with bitwise operations.
Octal (Base 8) in Unix/Linux
Octal numbers are commonly used for Unix file permissions. The permission value 755 (rwxr-xr-x) means the owner has read, write, and execute permissions, while group and others have read and execute only. Each octal digit represents three binary bits, making it compact for permission representation.
Hexadecimal (Base 16) in Programming
Hexadecimal is the preferred format for representing memory addresses, color codes (#FF5733), and byte values. Two hex digits represent exactly one byte (8 bits), making it more readable than binary. Web developers use hex colors daily, and programmers see hex values in debuggers and memory dumps.
Common Important Values
- 255 (decimal) = FF (hex) = 11111111 (binary) - Maximum value for one byte, used in RGB color values
- 256 (decimal) = 100 (hex) = 100000000 (binary) - Number of possible values in one byte (0-255)
- 64 (decimal) = 40 (hex) = 1000000 (binary) - 26, commonly used in encoding (Base64)
- 128 (decimal) = 80 (hex) = 10000000 (binary) - 27, number of ASCII characters

Decimal to Hexadecimal FAQ
How do I convert Decimal to Hexadecimal?
To convert decimal to hexadecimal, repeatedly divide by 16 and record the remainders. Remainders 10-15 become A-F. For example, 100 in decimal equals 64 in hexadecimal.
What is 100 decimal in hexadecimal?
100 in decimal equals 64 in hexadecimal. This conversion uses base 10 to base 16 transformation.
What is the formula for decimal to hexadecimal conversion?
To convert from decimal to hexadecimal (base 16): Divide the decimal number by 16 repeatedly, recording each remainder. The remainders, read from last to first, form the hexadecimal number.
Why would I need to convert decimal to hexadecimal?
Decimal to hexadecimal conversion is essential for web development (CSS colors like #FF5733), memory addresses in programming, and working with byte values in computing.
Can I convert negative numbers from decimal to hexadecimal?
This calculator handles positive integers. For negative numbers, you would typically use two's complement representation in binary, then convert. The sign is usually handled separately from the magnitude in most conversion scenarios.
