HEX to Binary

Convert hexadecimal numbers to binary quickly and accurately with the free HEX to Binary Converter from ToolsGram. Enter a hexadecimal value and instantly get its binary equivalent.

What Is a HEX to Binary Converter?

A HEX to Binary Converter is an online tool that converts hexadecimal numbers from the base-16 number system into binary numbers in the base-2 number system.

Hexadecimal uses sixteen symbols:

0–9 and A–F

Binary uses only:

0 and 1

The conversion is particularly straightforward because every hexadecimal digit corresponds exactly to four binary bits. This makes hexadecimal a compact way of representing binary information while still allowing easy conversion back to individual bits.

ToolsGram's HEX to Binary Converter automates this process so you do not need to convert each hexadecimal digit manually.

Common Use Cases

Programming

Developers frequently encounter hexadecimal values when working with memory addresses, bitwise operations, binary data, colors, and low-level programming.

Computer Science

Students can use HEX-to-binary conversion to understand how different number systems represent the same numerical value.

Digital Electronics

Hexadecimal and binary are commonly used together when representing digital states and working with binary-oriented systems.

Networking and Technical Data

Hexadecimal is often used as a compact representation of binary data, making conversion useful when analyzing technical information.

Debugging

Developers may need to inspect hexadecimal values at the binary level to understand individual bits and flags.

How Does HEX to Binary Conversion Work?

The conversion is based on a simple rule:

Each hexadecimal digit corresponds to exactly four binary digits.

For example:

A = 1010

and:

F = 1111

Therefore, if the hexadecimal number is:

AF

convert each digit independently:

• A → 1010
• F → 1111

Result:

AF₁₆ = 10101111₂

No decimal conversion is required.

Understanding HEX and Binary

Hexadecimal

Hexadecimal is a base-16 number system containing sixteen symbols:

Decimal	HEX
0	0
1	1
2	2
3	3
4	4
5	5
6	6
7	7
8	8
9	9
10	A
11	B
12	C
13	D
14	E
15	F

Binary

Binary is a base-2 number system that uses only two digits:

Binary Digit	Value
0	0
1	1

Each binary position represents a power of 2.

HEX to Binary Conversion Table

The most important table for HEX-to-binary conversion is:

HEX	Binary
0	0000
1	0001
2	0010
3	0011
4	0100
5	0101
6	0110
7	0111
8	1000
9	1001
A	1010
B	1011
C	1100
D	1101
E	1110
F	1111

This table allows any hexadecimal value to be converted directly into binary.

HEX to Binary Examples

Example 1: Convert 5 to Binary

The hexadecimal digit 5 corresponds to:

0101

Therefore:

5₁₆ = 0101₂

Example 2: Convert A to Binary

The hexadecimal digit A represents decimal 10.

Its four-bit binary representation is:

1010

Therefore:

A₁₆ = 1010₂

Example 3: Convert 2F to Binary

Convert each hexadecimal digit separately:

• 2 → 0010
• F → 1111

Therefore:

2F₁₆ = 00101111₂

Example 4: Convert B7C to Binary

Convert each digit:

• B → 1011
• 7 → 0111
• C → 1100

Combine them:

B7C₁₆ = 101101111100₂

Example 5: Convert 1A3F to Binary

Convert each hexadecimal digit:

• 1 → 0001
• A → 1010
• 3 → 0011
• F → 1111

Result:

1A3F₁₆ = 0001101000111111₂

Why Convert HEX to Binary?

Hexadecimal is compact, but binary makes individual bits visible.

For example:

FF

is only two hexadecimal characters, while its binary representation is:

11111111

The binary form makes it possible to examine each individual bit.

This is especially useful for:

• Bitwise operations
• Binary flags
• Digital logic
• Programming
• Computer architecture
• Debugging
• Embedded systems
• Network data analysis

Manual HEX to Binary Conversion

Converting hexadecimal to binary manually is straightforward.

Step 1: Separate the HEX digits

For example:

3A7F

contains four hexadecimal digits.

Step 2: Convert each HEX digit into four bits

• 3 → 0011
• A → 1010
• 7 → 0111
• F → 1111

Step 3: Combine the results

3A7F → 0011 1010 0111 1111

Therefore:

3A7F₁₆ = 0011101001111111₂

The key is to keep four binary digits for every hexadecimal digit, including leading zeros.

Why Are Four Binary Bits Used?

A hexadecimal digit can represent values from 0 to 15.

Four binary bits can also represent values from 0 to 15:

0000 through 1111

That is why the two systems align perfectly.

HEX Digits	Binary Bits
1	4
2	8
3	12
4	16
8	32
16	64

So a 16-digit hexadecimal number corresponds to 64 binary bits.

HEX vs Binary

Feature	HEX	Binary
Base	16	2
Symbols	0–9, A–F	0–1
Bits represented per digit	4	1
Compactness	High	Low
Human readability	Easier for long values	More difficult for long values
Common use	Programming and technical data	Machine-level representation
Example	A5	10100101

HEX, Binary, and Decimal

The same numerical value can be represented in different number systems.

For example:

A₁₆ = 10₁₀ = 1010₂

Another example:

FF₁₆ = 255₁₀ = 11111111₂

Understanding the relationship between these systems is an important part of computer science and programming.
