Each hexadecimal digit represent four binary bits. Using the table... 0 = 0000 1 = 0001 2 = 0010 3 = 0011 4 = 0100 5 = 0101 6 = 0110 7 = 0111 8 = 1000 9 = 1001 A = 1010 B = 1011 C = 1100 D = 1101 E = 1110 F = 1110 ... replace each hexadecimal digit with its correspnding binary digits. As an example, 37AB16 is 00110111101010112.

LaoIf the number of bits in the binary value is not an exact multiple of four, pad the binary value with leading zeros. So 1010110100 becomes 001010110100. Split the binary value into groups of 4 bits: 0010, 1011 and 0100. Each group is a nybble (half-a-byte). Convert each nybble to its corresponding hexadecimal digit, as shown below:
0000 = 0x0
0001 = 0x1
0010 = 0x2
0011 = 0x3
0100 = 0x4
0101 = 0x5
0110 = 0x6
0111 = 0x7
1000 = 0x8
1001 = 0x9 1010 = 0xA
1011 = 0xB
1100 = 0xC
1101 = 0xD
1110 = 0xE
1111 = 0xF
Thus we get 0x2, 0xB and 0x4. Combining these hex digits in the same order we get 0x2B4, the hexadecimal equivalent of 1010110100.
Note that we can do the same thing to get the octal notation of a binary value, except we divide the binary value into groups of 3 bits, and convert as follows:
000 = 00
001 = 01
010 = 02
011 = 03
100 = 04
101 = 05
110 = 06
111 = 07
Thus 1010110100 becomes 001 010 110 100 which is 01264 in octal.
Note also that all bases that are a power of two (4, 8, 16, 32, 64 and so on), can be used to notate binary values. We use hexadecimal (base 16) simply because it reduces an 8-digit binary value to a 2-digit hexadecimal value which is much easier to notate. We use octal notation when the bit lengths are some multiple of 3 or when it is more notationally convenient to represent the value in groups of 3 bits, and use binary notation only when we're actually interested in the binary representation itself (the actual bits).
Start at the binary point (bp) - the binary equivalent of the decimal point.Group the binary digits into sets of four.
If there are not enough digits add one to three 0s furthest away from the bp.
The hexadecimal point will be in the same position as the binary point. And convert each binary quartet into the hexadecimal equivalent as follows:
0000 = 0 0001 = 1 0010 = 2 0011 = 3
0100 = 4 0101 = 5 0110 = 6 0111 = 7
1000 = 8 1001 = 9 1010 = A 1011 = B
1100 = C 1101 = D 1110 = E 1111 = F

Why people are using Hexadecimal rather than binary numbers while doing programs?
hexadecimal can express 16 bit binary in 4 place form, not 16.
What does hexadecimal base 16 convert binary equal?
16 is the 4th power of 2. So a hexadecimal number is converted to binary by replacing each hex digit by the 4-bit binary number having the same value. Conversely, in converting binary to hexadecimal, we group every 4 bits starting at the decimal (binary?) point and replace it with the equivalent hex digit. For example, the hexadecimal number 3F9 in binary is 1111111001, because 3 in binary is 11, F (decimal 15) is 1111, and 9 is 1001.
How do you convert hexadecimal 4c.B7 to Binary?
Convert each hex digit to four binary digits. If you get less than three (for example, 7 --> 111), fill it out with zeroes to the left (in this case, 0111).
The minimum number of bits required to store the hexadecimal number FF is?
To store the hexadecimal number FF, we need to convert it to binary first. FF in hexadecimal is equivalent to 1111 1111 in binary, which requires 8 bits to represent. Each hexadecimal digit corresponds to 4 bits in binary, so two hexadecimal digits (FF) require 8 bits to store.
What is the 4-binary number assoiated with the hexadecimal symbol C?
0xc = 1100 Hexadecimal digits use exactly 4 binary digits (bits). The 0x0 to 0xf of hexadecimal map to 0000 to 1111 of binary. Thinking of the hexadecimal digits as decimal numbers, ie 0x0 to 0x9 are 0 to 9 and 0xa to 0xf are 10 to 15, helps with the conversion to binary: 0xc is 12 decimal which is 8 + 4 → 1100 in [4 bit] binary.
