Conversion of octal numbers to hexadecimal

Converting octal numbers to hexadecimal is mediated by binary system of numbers like this example :

Direct conversion from hexadecimal to binary

Passing directly from hexadecimal system to binary system of numbers is done by finding for each digit hexadecimal number four bit binary equivalent

Example: 

Directly converting from Binary to Hexadecimal

For the conversion of a numeral system to another system, can be used as an intermediary decimal system of numbers.
• Many complex calculations
• in practice used direct switching between numeral systems.


Converting from binary system to hexadecimal system is on two steps :
Binary number is divided into groups of 4 digits starting from the right.
Each group has an equivalent hexadecimal number

Example : 

Converting from hexadecimal to decimal numbers

As octal and binary system hexadecimal number system conversion can be done using the formula

For the base numerical system will be B = 16

Example :

Hexadecimal numeral system

Hexadecimal system, the numbers are written using 16 different digits:

0 1 2 3 4 5 6 7 8 9 A B C D E F

Since hexadecimal numbering system used 16 different digits, the basis of this numerical system is B = 16.


Transformation procedure hexadecimal floating point numbers in the same as the previous systems.
• divide the base 16
