How to Convert Hex to Decimal: A Comprehensive Guide

Converting hexadecimal (hex) numbers to decimal is a fundamental skill in programming and electronics. Hexadecimal is a base-16 number system used widely in computer science due to its simplicity in representing binary-coded values. This guide will walk you through the process of converting hex to decimal, provide real-world examples, and answer common questions about the conversion process. Additionally, we'll introduce you to our online tools that can help streamline this task.

Understanding Hexadecimal and Decimal Systems

Hexadecimal System

The hexadecimal system uses 16 symbols: 0-9 to represent values zero to nine and A-F (or a-f) to represent values ten to fifteen. It is particularly useful in computing as it can represent large binary numbers in a more compact and readable form.

Decimal System

The decimal system is a base-10 number system using symbols 0-9. It is the most commonly used number system for arithmetic operations in everyday life.

Step-by-Step Guide to Convert Hex to Decimal

Step 1: Write Down the Hex Number

For example, let's convert the hex number 1A3.

Step 2: Assign Powers of 16

Starting from the right, assign powers of 16 to each digit. The rightmost digit has the power 16^0, the next has 16^1, and so on:

1A3 = 1*(16^2) + A*(16^1) + 3*(16^0)

Step 3: Convert Hex Digits to Decimal

Convert each hex digit to its decimal equivalent:

1 -> 1
A -> 10
3 -> 3

Step 4: Perform the Multiplication

Multiply each digit by its corresponding power of 16:

1*(16^2) = 1*256 = 256
10*(16^1) = 10*16 = 160
3*(16^0) = 3*1 = 3

Step 5: Sum the Results

Add the results of the multiplications:

256 + 160 + 3 = 419

So, the decimal equivalent of 1A3 is 419.

Examples

Example 1: Convert 2F to Decimal

2F = 2*(16^1) + F*(16^0)
2*(16^1) = 2*16 = 32
F = 15
15*(16^0) = 15*1 = 15
32 + 15 = 47

Decimal equivalent of 2F is 47.

Example 2: Convert B4 to Decimal

B4 = B*(16^1) + 4*(16^0)
B = 11
11*(16^1) = 11*16 = 176
4*(16^0) = 4*1 = 4
176 + 4 = 180

Decimal equivalent of B4 is 180.
