Hexadecimal to binary conversion

The following procedure can be used for converting the hexadecimal to binary number:

Step 1 : Write the Hexadecimal number
Step 2 : Write the four digit equivalent binary number

Example: To convert the hexadecimal number 7A.2D to binary number

Step 1 : 7 A . 2 D (Hexadecimal number)
Step 2 : 0111 1010 . 0011 1101 (Binary equivalent)

Therefore, 7A.2D 16 = 1111010.00111101 2

Hexadecimal to Octal conversion

The following procedure can be used for converting the hexadecimal number to octal
number:

Step 1 : First convert the hexadecimal number to binary number
Step 2 : Then, convert the binary number to octal number (procedure already given)

Example: To convert the hexadecimal number 7A.2D to octal number

Step 1 : 7 A . 2 D (Hexadecimal number)
Step 2 : 0111 1010 . 0011 1101 (Binary equivalent)
Step 3 : 001 111 010 . 001 111 010 (Group of 3-bits)
Step 4 : 1 7 2 . 1 7 2 (Octal number)

Therefore, 7A.2D 16 = 172.172 8
