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

Understanding D in Hexadecimal

The value D in hexadecimal (base 16) can be expressed in multiple number systems:

Decimal (Base 10):
13
Binary (Base 2):
1101
Octal (Base 8):
15
Hexadecimal (Base 16):
D

Hexadecimal to Decimal FAQ

How do I convert Hexadecimal to Decimal?

To convert hexadecimal to decimal, multiply each digit by 16 raised to its position power, then sum all results. Digits A-F represent 10-15. For example, D in hexadecimal equals 13 in decimal.

What is D hexadecimal in decimal?

D in hexadecimal equals 13 in decimal. This conversion uses base 16 to base 10 transformation.

What is the formula for hexadecimal to decimal conversion?

To convert from hexadecimal to decimal: For each digit, multiply by 16 raised to the power of its position (starting from 0 on the right), then sum all results.

Why would I need to convert hexadecimal to decimal?

Hexadecimal to decimal conversion helps interpret memory addresses, color codes, and byte values in human-readable decimal format.

Can I convert negative numbers from hexadecimal to decimal?

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.
