Directly converting from binary system to octal number system

Converting from binary system to octal number system is done in the same way as converting binary system to hexadecimal system of numbers
Binary digits of the number are grouped into groups of 3 digits.

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 : 

Shortly for the Binary numbers system

Digital system to which the numbers are written using only the digits 0 and 1 is called the binary number system.
Binary numbers base is B = 2.
Numbering system that is used by computers for all calculations
An example of binary string :
11010111011
