Hexadecimal (Hex)

The hexadecimal system (base-16) uses 16 symbols (0–9 and A–F). It is widely used in computing to represent binary data in a shorter, readable way. Each hex digit corresponds to a group of four binary digits.

Key Facts About Hexadecimal

• Exact value: Base-16 system.
• Relationship to other units: 1 hex digit = 4 binary digits.
• Common abbreviation: hex.
• Notation tips: Often written with prefix 0x or a subscript 16.

Binary (Bin)

The binary number system (base-2) uses only 0 and 1. Each digit is a bit, and 8 bits form a byte. Computers store all information—text, images, and programs—in binary format.

Key Facts About Binary

• Exact value: Smallest unit is 1 bit.
• Relationship to other units: 1 byte = 8 bits.
• Common abbreviation: bin.
• Notation tips: Often written with prefix 0b or subscript 2.

Hex to Binary Conversion Formula

Formula:

Binary value = Each hex digit converted into 4 binary bits

Hex to Binary Conversion Examples

Example 1: Convert Hex A to Binary

Step 1: Formula = Binary = Hex digit expanded

Step 2: Substitute = A = 101

Step 3: Result = 1010

Example 2: Convert Hex 3F to Binary

Step 1: Binary = Each hex digit written in 4 bits

Step 2: Substitute = 3 = 0011, F = 1111

Step 3: Result = 00111111

Example 3: Convert Hex 7B to Binary

Step 1: Binary = Each hex digit written in 4 bits

Step 2: Substitute = 7 = 0111, B = 1011

Step 3: Result = 01111011

Binary to Hex Conversion Formula

Formula:

Hex value = Binary digits grouped into 4 bits

Binary to Hex Conversion Examples

Example 1: Convert 1010 (binary) to hex

Step 1: Hex = Binary grouped in 4 bit

Step 2: Substitute = 1010 = A

Step 3: Result = A

Example 2: Convert 110101 (binary) to hex

Step 1: Hex = Group into 4 bits = 0011 0101

Step 2: Convert = 0011 = 3, 0101 = 5

Step 3: Result = 35

Example 3: Convert 11111111 (binary) to hex

Step 1: Group binary into 4 bits = 1111 1111

Step 2: Convert = F = 1111

Step 3: Result = FF

Applications of Hex and Binary Conversions

• Programming: Memory addressing and debugging.
• Networking: IP and MAC addresses often displayed in hex.
• Web Design: Color codes like #FF0000 use hex.
• Embedded Systems: Data storage and microcontroller instructions.
