Binary to Hexadecimal Conversion
In the world of computing, data is represented using various numeral systems, such as binary, decimal, and hexadecimal. Binary is a base-2 numeral system that uses only two symbols, typically 0 and 1, to represent data. Hexadecimal is a base-16 numeral system that uses sixteen distinct symbols, 0-9 and A-F. Sometimes, we need to convert between these systems to make data more readable or to simplify calculations. In this topic, we will learn how to convert binary to hexadecimal, a process commonly referred to as binary to hexadecimal conversion.
What is Binary?
Binary is a numeral system that represents numeric values using two symbols, typically 0 and 1.
It is the foundation of all binary code, which is used in computer and digital systems and is central to tasks such as binary to hex conversion.
Each digit in a binary number is referred to as a bit. Binary is a base-2 system, meaning each digit represents a power of 2.
What is Hexadecimal?
Hexadecimal is a numeral system that represents values using sixteen symbols: 0-9 for values zero to nine, and A-F for values ten to fifteen.
It is a base-16 system commonly used in computing and digital electronics because it can represent large binary numbers more compactly, making binary to hexadecimal conversion easier to understand.
What Is Binary to Hexadecimal Conversion?
Binary to hexadecimal conversion is the process of changing a number written in binary (base 2) into its equivalent value in hexadecimal (base 16).
Both number systems are widely used in computers and digital electronics because they make it easier to represent and understand binary data.
Computers store all information in binary, using only 0s and 1s. However, long binary strings can be hard to read and work with.
Hexadecimal simplifies this by grouping binary digits into sets of four, allowing each group to be represented by a single hexadecimal digit.
This makes it easier for students, programmers, and engineers to read and debug digital information.

Binary to Hexadecimal Formula
To perform binary to hexadecimal conversion, follow these steps, which together form the standard binary to hexadecimal conversion formula:
- Group the binary digits into sets of four bits (starting from the right).
- Add leading zeros if the leftmost group has fewer than four bits.
- Convert each 4-bit binary group to its corresponding hexadecimal digit.
For example:
- 1010 → A
- 1100 → C
- 1111 → F
This method is also useful when consulting a binary to hexadecimal conversion table, which shows binary values alongside their hexadecimal equivalents.
How to Convert Binary to Hexadecimal?
Converting binary to hexadecimal involves grouping binary digits into sets of four and then translating each group to a single hexadecimal digit, a process frequently supported by an online binary to hexadecimal calculator for quick computation.
Step-by-Step Process to Convert Binary to Hexadecimal
Step 1: Write down the binary number and group the digits in sets of four, starting from the right.
Step 2: Convert each group to its hexadecimal equivalent.
Step 3: Combine these hexadecimal digits to get the final result.
Binary to Hexadecimal Conversion Chart
When converting binary to hexadecimal, it helps to have a chart for quick reference.
Below is a chart showing the conversions for 4-bit binary numbers to hexadecimal digits.

Common Mistakes and How to Avoid Them in Binary to Hexadecimal Conversion
When converting binary to hexadecimal, people often make mistakes.
Here are some common errors and tips to avoid them.
Mistake 1
Not grouping in sets of four
Skipping the step of grouping binary digits into sets of four can lead to incorrect conversions.
Always ensure each group is complete by adding leading zeros if necessary.
Mistake 2
Incorrect conversion of groups
Errors occur when converting binary groups to hexadecimal digits.
Double-check each group against a conversion chart to prevent mistakes.
Mistake 3
Misplacing digits
Reversing the order of hexadecimal digits can lead to incorrect results.
Ensure that you maintain the correct sequence as you convert and combine the groups.
Mistake 4
Confusing binary and hexadecimal symbols
Confusion arises when people mix up binary (0,1) and hexadecimal symbols (0-9, A-F).
Familiarize yourself with both systems to avoid errors.
Mistake 5
Overlooking leading zeros
Neglecting to add leading zeros in the binary groups can lead to incomplete conversions. Ensure each group has four bits by adding zeros where needed.
Binary to Hexadecimal Conversion Examples
Problem 1
Convert 101010 to Hexadecimal
101010 = 2A
Explanation
Step-by-step conversion:
Group the binary number (add leading zeros): 0010 1010 2.
Convert each group: 0010 = 2, 1010 = A
Result: 2A
Problem 2
Convert 100110 to Hexadecimal
The hexadecimal equivalent is 26.
Explanation
Step-by-step conversion:
Group the binary number (add leading zeros): 0010 0110
Convert each group: 0010 = 2, 0110 = 6
Result: 26
Problem 3
Converting 11111111 to Hexadecimal
11111111 = FF
Explanation
Step-by-step conversion:
Group the binary number: 1111 1111
Convert each group: 1111 = F, 1111 = F
Result: FF
Problem 4
A college student in Boston is shopping at Target, planning to buy a $1,299 laptop to watch NBA games and complete computer science homework. During class, the professor gives the binary number 10110110โ and asks students to convert it into hexadecimal.
B6
Explanation
Binary to hexadecimal conversion is done by breaking the binary number into groups of 4 bits:
1011 → B
0110 → 6
So 10110110โ = B6โโ.
This conversion is commonly used in computer memory discussions, which the student encounters during CS labs in Boston.
Problem 5
A CVS in Los Angeles (LA) updates its digital inventory for a new medicine batch costing $42 per unit. The scanner logs a binary tracking code 110011001010โ. The pharmacist must convert it to a hexadecimal value to sync with the national system.
CC A
Explanation
First, pad the binary number on the left to make groups of 4:
Binary: 1100 1100 1010
- 1100 → C
- 1100 → C
- 1010 → A
So the tracking code becomes CCAโโ, which is easier for pharmacy inventory systems across the US to read.
