Decimal:
The hexadecimal can be
converted to decimal by using the 16n system…
Eg:
C616
Hexadecimal C 6
Decimal * 12×161 6×160 =
192 + 6 = 19810
* (C is equal to 12 in the Number System
Conversion of hexadecimal)
Eg 2 :
FFD4.F16
Hexadecimal F F D 4 . F
Decimal *15×163 15×162 **13×161 4×160 . 15×16-1
=61440 + 3840 +
208 + 4+0.9375
=65492.937510
(* 15 is equal to
the F in the Number System Conversion of
hexadecimal…
**13 is equal to the D in the Number System
Conversion of hexadecimal…)
Binary:
The conversion of
hexadecimal to binary
by 3 methods:
·
According
to the Number System Conversion between hexadecimal and binary
·
By using
the 2n system
Eg :
2C16
Method 1: Converting
to decimal and then to binary
Hexadecimal 2 C
Decimal 2×161 12×160
= 32+ 12 =4410
Then convert the
decimal into binary by using division…

4410 =

And also can written
as …
2C16 =
1011002
Method 2 : According
to the Number System Conversion between hexadecimal and binary
Hexadecimal 2 C
Binary 0010 1100
·
2C16 = 10
11002
Method 3: By using the
2n system
---when converting the binary into hexadecimal ,we
need to group the binary into 4…and the 4 of grouped binary are indicated by
the 2n system…
For example, the most left of the grouped binary indicate the 23,next
is 22 , followed by 21, and lastly is 20
So,
2C16 = 0010 11002
(00102 = (
0×23)+(0×22)+(1×21)+(0×20)=0+0+2+0=216;
11002 =(1×23) + (1×22) + (0×21) + (0×20) = 8+4+0+0=
12=C16)
Eg 2:
C6.F16
We convert according
the Number System Conversion between the hexadecimal and binary…
Hexadecimal C 6 . F
Binary 1100 0110 1111
So,
C6.F16
= 1100 0110.11112
Octal:
There are few ways to
convert the hexadecimal to octal:
·
Convert
the hexadecimal into decimal and then to octal
·
Convert
the hexadecimal into binary and then to octal
Eg :
4A16
Method 1: Convert the
hexadecimal into decimal and then to octal
Hexadecimal 4 A
Decimal 4×161 10×160
= 64 + 10 =7410
Convert to octal by
dividing the decimal with 8…

4A16 = 1128
Method 2 : Convert the
hexadecimal into binary and then to octal
Hexadecimal 4 A
Binary * 0100 **1010
* ((0×23) + (1×22) + (0×21) + (0×20) =416)
**((1×23) + (0×22) + (1×21) + (0×20) = 10 =A16)
4A16 = 100
10102
Convert to octal by
grouping the binary into 3…
100 10102 = 001
| 001 | 0102
Then , according to
the Number System Conversion between Octal and binary…

Or …
By using the 2n
system…
100 10102
= 001 |
001 | 0102
=((0×22)+(0×21)+(1×20)) |((0×22)+(0×21)+(1×20)) | ((0×22)+(1×21)+(0×20))
=1 | 1
| 28
Therefore ,
4A16 = 1128
Eg 2 :
6A.B16
Converting to binary …
Hexadecimal 6 A . B
Binary 0110 1010 .
1011
6A.B16 =
1101010.10112
Converting into octal…
1101010.10112
= 001 |101 |010. |101 | 100
(According to the
Number System Conversion between octal and binary)
= 1 |
5 | 2 .
| 5 |48
Therefore,
6A.B16 =
152.548
