Octal number system

An octal system or it is called the base eight system .The digits in octal maths are 0,1,2,3,4,5,6,7.The value of “!” is written as eight and 0 as ones or 108 .

octal to hexadecimal conversion

While converting from  octal to  hexadecimal unit, it is a usual practice to convert the octal to hexadecimal by converting the octal number into binary digit and then further to from binary to hexadecimal.For example to convert the number 536 from octal to hexadecimal.

Example:

Convert 536 from octal to  hexadecimal number

Convert 536(octal) into its binary equivalent we get
(536)8 = (101) (011) (110)
=(101011110)2
Now forming the group of 4 binary bits to obtain its hexadecimal equivalent,
(101011110)2= (0001) (0101) (1110)
= (15E)16

So the hexadecimal number of 536 is 15E.
