binary to hexadecimal – How to convert BIN to HEX
Converting binary to hexadecimal is a key process in computer science, digital design, and programming. While binary (BIN) is the language computers use, hexadecimal (HEX) makes that language shorter, cleaner, and easier for humans to read. This conversion helps bridge the gap between raw binary code and readable digital data.
What is a binary (BIN)?
The binary system is a base-2 numeral system composed of only two digits: 0 and 1. Each binary digit represents a power of two, starting from 2⁰ on the right. Computers use binary because their electronic circuits operate in two states—on and off.
Example:
1011₂ = 1×2³ + 0×2² + 1×2¹ + 1×2⁰ = 8 + 0 + 2 + 1 = 11₁₀
Every text, image, and sound file is stored in binary form, where each bit plays a crucial role in digital information.
What is a hexadecimal (HEX)?
The hexadecimal system is a base-16 numeral system that uses sixteen symbols: 0–9 and A–F, where A represents 10 and F represents 15 in decimal. It’s a compact way to represent large binary numbers, making programming and debugging more efficient.
Example:1A₁₆ = 1×16¹ + 10×16⁰ = 16 + 10 = 26₁₀
Hexadecimal is widely used in computing, from color codes in web design (like #FF5733) to memory addresses and machine-level programming.
How to convert binary to hexadecimal
Hexadecimal and binary are closely related because one hexadecimal digit equals exactly four binary digits (bits). To convert binary to hexadecimal, divide the binary number into groups of four bits (starting from the right), and convert each group into its hexadecimal equivalent.
Binary to Hexadecimal Chart:
0000 = 0 0100 = 4 1000 = 8 1100 = C
0001 = 1 0101 = 5 1001 = 9 1101 = D
0010 = 2 0110 = 6 1010 = A 1110 = E
0011 = 3 0111 = 7 1011 = B 1111 = F
Example:101101₍₂₎ → 0010 1101 → 2D₍₁₆₎
So, binary 101101₂ is equal to hexadecimal 2D₁₆.

Do you know?
-
About Binary: In 1937, Claude Shannon’s master’s thesis at MIT demonstrated how binary algebra could represent logical circuits, laying the foundation of digital computing.
-
About Hexadecimal: The hexadecimal system became popular with early programmers because it could represent a full byte (8 bits) with just two symbols—making reading and debugging far more efficient.
-
Binary in Design: Every digital color on your screen—like pure red #FF0000—is a hexadecimal value derived directly from binary-coded RGB data.
-
Hexadecimal in Space: NASA’s spacecraft computers often use hexadecimal for memory addresses and command sequences because it’s compact and reduces transmission errors compared to long binary strings.
The Story Behind Binary and Hexadecimal
In the early days of computing, programmers had to work directly with binary code—long strings of 0s and 1s. As systems grew more complex, these strings became nearly impossible to read and debug. That’s when engineers introduced hexadecimal notation as a shorthand form of binary.
By grouping every four binary bits into one hexadecimal digit, engineers could interpret and modify machine code much faster. This change revolutionized programming. Suddenly, what once looked like endless streams of numbers became organized and readable.
In modern design, hexadecimal continues to play an artistic role. Every time a web designer selects a color using a hex code, they’re interacting with binary values hidden beneath the surface. For instance, #FFFFFF represents pure white in RGB format—binary numbers translated into hexadecimal symbols for convenience and clarity.
From microprocessors to modern web design, the connection between binary and hexadecimal is a reminder of how efficiency drives innovation. It’s a perfect partnership: binary for machines, hexadecimal for humans.

Turning Binary into Hexadecimal
The binary to hexadecimal relationship is more than a mathematical conversion—it’s the key to clear communication between digital systems and the people who build them. By simplifying complex binary data, hexadecimal makes coding, debugging, and digital design faster and more intuitive.
Binary speaks the language of logic. Hexadecimal turns that logic into clarity. Together, they shape the backbone of every digital experience you see, use, and create.
