Hexadecimal to Binary Conversion

Today, we will learn how to convert hexadecimal numbers into binary. Remember, each hex digit corresponds to a unique four-bit binary equivalent due to their base relationship. Can anyone tell me what hexadecimal numbers include?
Are the hex numbers just 0 to 9 and then A to F?
Exactly! That's excellent, Student_1. So, for example, the hex digit A translates to what binary equivalent?
Is it 1010?
That's right! To remember this, you might think of it as counting in binary while using up to the letter F. Now let's try a conversion together – what is the binary equivalent of B?
That's 1011!
Good job, everyone! Let’s recapitulate – to convert hex to binary, replace each hex digit with its four-bit counterpart.

Now, let’s shift gears. When we convert binary to hexadecimal, what do we do?
Do we group the binary digits into sets of four?
Correct! We start from the binary point and group digits into sets of four. If we have fewer than four, we can add zeros at the start. Can someone give me an example?
If we have 10111010.101, then we can group it as 0101 1101 1010?
Perfect! And what would each group translate to in hexadecimal?
That would be 5DA.
Exactly! So remember: for binary to hex, always make those four-bit groups.

Quick Overview
Standard
Hexadecimal to binary conversions involve replacing each hex digit with its four-bit binary equivalent due to the base-16 relationship with base-2. Conversely, binary to hexadecimal conversions require grouping binary digits into sets of four. These conversions are essential for understanding data representation in digital systems.

Hex–Binary and Binary–Hex Conversions
This section focuses on the conversion between hexadecimal (base-16) and binary (base-2) number systems, which is crucial in various digital electronic applications. When converting a hexadecimal number to binary, each hex digit is transformed into its corresponding four-bit binary form. This is possible because the base of the hexadecimal system (16) is the fourth power of the binary base (2), allowing for a direct mapping of each of the 16 digits (0-9 and A-F) to a unique four-bit pattern.
For instance, the hex digit 'A' corresponds to '1010' in binary. Conversely, converting from binary to hex involves grouping binary digits in sets of four, from the binary point outwards, and translating each group into its hex equivalent. Leading or trailing zeros can be added as necessary to ensure that each group is complete. This duality in conversion is a critical skill for anyone involved in computer systems and digital electronics as it streamlines data representation and manipulation.

A hexadecimal number can be converted into its binary equivalent by replacing each hex digit with its four-bit binary equivalent. We take the four-bit equivalent because the base of the hexadecimal number system is 16 and it is the fourth power of the base of the binary number system. All we have then to remember is the four-bit binary equivalents of the basic digits of the hexadecimal number system.
Detailed Explanation
Hexadecimal numbers consist of 16 symbols: 0-9 and A-F, where A-F represent the values 10-15. Each hex digit can be represented by a 4-bit binary number because 2^4 = 16, perfectly matching the number of hex symbols. To convert a hex number to binary, you take each hex digit and replace it with its corresponding 4-bit binary equivalent. For example, the hex digit 'A' corresponds to '1010' in binary. Thus, the hexadecimal number '1A3' converts to binary by changing '1' to '0001', 'A' to '1010', and '3' to '0011', resulting in '000110100011'.
Examples & Analogies
Think of a color palette where each color is represented by a mix of RGB values in hexadecimal. Each color hex code (like #FF5733) can be broken down into its components (FF, 57, 33). Converting these colors to binary means knowing how many bits are used to represent each color and what their values are, similar to knowing an artist’s color mixing recipes.

A given binary number can be converted into an equivalent hexadecimal number by splitting the integer and fractional parts into groups of four bits, starting from the binary point on both sides. The 0s can be added to complete the outside groups if needed.
Detailed Explanation
To convert a binary number to hexadecimal, you divide the number into groups of four bits each, starting from the point (binary point) towards both left and right sides. For example, the binary number '11011011100' can be grouped as '0011 0110 1110 0' (adding zero to the leftmost group to complete it). Each group of four bits corresponds to a single hex digit: '0011' becomes '3', '0110' becomes '6', and '1110' becomes 'E'. Thus, '11011011100' in binary is '36E' in hexadecimal.
Examples & Analogies
Imagine you have a box of chocolates divided into smaller containers, each holding exactly 4 chocolates. To count how many chocolates you have, you check the containers one by one, knowing that every container holds the same number of chocolates. Similarly, in binary-to-hex conversion, you look at each group of four bits like a container, and each unique container corresponds to a unique hex digit.

Example 1.7: Let us find the binary equivalent of (17E.F6) and the hex equivalent of (1011001110.011011101).
Detailed Explanation
In this example, we first convert the hexadecimal number '17E.F6'. We convert each character: '1' is '0001', '7' is '0111', 'E' is '1110' (which is 14 in decimal), and 'F' is '1111' (15 in decimal). Therefore, '17E.F6' in binary becomes '000101111110.11110110' or without leading zeros, '101111110.1111011'.
For the binary number '1011001110.011011101', we need to convert it to hexadecimal. Group the integer part as '0010 1100 1110' and the fractional part as '0110 1110 1000'. Each group converts to hex: '0010' is '2', '1100' is 'C', '1110' becomes 'E', and so on, resulting in a hex number of '2CE.6E8'.

When converting recipes from one measurement system to another (like cups to liters), you have to understand the proportion of each ingredient. In conversions, every section (like each measurement or bit) has its corresponding value that needs to be changed carefully to maintain the integrity of the recipe, ensuring you don’t over or under-prefer the ingredients.
